NASA’s Lucy Begins Camera Tests Ahead of 2027 Trojan Flybys — NASA Science The spacecraft’s instruments are undergoing calibration checks before the first Trojan asteroid encounters. Lucy will fly past multiple asteroids in Jupiter’s leading and trailing swarms. Early imaging data will confirm the cameras can resolve surface features at the planned distances. The mission team is adjusting exposure settings based on the latest test results. These tests ensure the spacecraft can capture both color and stereo images during the 2027 flybys. APOD: 2026 August 7 – Rubin’s Cosmos Field — NASA Science The image shows a wide-field view of the southern sky captured during early operations of the Vera C. Rubin Observatory. It reveals thousands of galaxies and stars across a single exposure. The observatory’s rapid scanning capability will eventually map the entire visible sky every few nights. This particular field highlights the telescope’s ability to detect faint, moving objects. Data from these early images are already being used to refine survey strategies. Sensing the Poles’ Hidden Heat — NASA Science NASA’s PREFIRE mission has produced animations showing seasonal temperature changes at both poles over two years. The data reveal how heat escapes from Earth’s surface through the atmosphere in polar regions. Instruments measure far-infrared radiation that was previously difficult to observe from space. The observations help refine climate models that predict ice loss and atmospheric circulation. Continued measurements will track how these patterns evolve year to year. Charting the Galaxy: Milky Way Mapper Survey Releases Latest Spectra — Phys.org Space SDSS-V’s twentieth data release includes expanded spectroscopic observations of stars throughout the Milky Way. The Milky Way Mapper component now covers a much larger volume of the galactic disk and halo. Astronomers can use the new spectra to trace chemical abundances and stellar motions at greater distances. The release adds thousands of new targets observed with multiple instruments. Future data releases will further increase the density of the map. Trillion-Mile Gas Streamer May Explain Tilt of Triple-Star Disk — Phys.org Space ALMA observations captured a narrow stream of gas stretching 0.2 light-years into the GW Orionis system. The streamer appears to be feeding material into the young triple-star system from surrounding clouds. This inflow is thought to be responsible for warping the outer planet-forming ring. The data provide the clearest view yet of how external material can alter disk orientation. Follow-up observations will track whether the streamer continues to deliver mass over time. Milky Way-like Simulation Reveals How Central Galactic Structures Grow — Phys.org Space New simulations model the formation of nuclear star clusters and nuclear stellar disks around supermassive black holes.

Researchers tracked how different orbital families contribute to the final morphology. The results will guide interpretation of upcoming high-resolution observations of galactic centers. Two Decades of Blazar Observations Raise New Questions — Phys.org Space A Polish-German team analyzed long-term variability in one blazar’s jet emission across multiple wavelengths. The extended dataset shows complex patterns that do not fit existing single-zone models. Brightness changes appear on timescales from hours to years, suggesting multiple emission regions. The study highlights gaps in understanding how particles are accelerated in these jets. Additional multi-wavelength campaigns are planned to test revised models. Educators and Teens Work with TEMPO Air Quality Data — NASA Science The CosmicDS project partnered with the Smithsonian to give students hands-on access to TEMPO satellite measurements. Participants examined nitrogen dioxide levels over North American cities using real-time data. The program ran from July 27 to 29 and included training on interpreting satellite imagery. Students compared local ground measurements with the satellite views. The effort aims to build skills for future citizen-science air quality projects. Super-Earths May Be Solid Deep Inside Their Mantles — Phys.org Space High-pressure experiments show that common mantle minerals in super-Earths transform into denser phases under extreme conditions. These new phases could make the interiors of planets between one and ten Earth masses more rigid than expected. The findings affect models of how heat flows and how magnetic fields might be generated. Researchers are mapping the exact pressure-temperature boundaries for these transitions. Future studies will test whether the same behavior occurs in planets with different compositions. JWST Study Suggests Few Leaky Galaxies Reionized the Early Universe — Phys.org Space Spectra of more than 1,400 galaxies indicate that a small subset with high escape fractions of ionizing photons drove reionization. The James Webb Space Telescope data show these galaxies had the right properties to clear neutral hydrogen from the intergalactic medium. The result challenges earlier assumptions that a much larger population was required. The paper was posted to arXiv on July 24. Additional JWST observations will test whether this pattern holds across other fields. Canada Repurposes Canadarm3 Investments for Lunar Exploration — PR Newswire Canada The Canadian Space Agency announced plans to redirect resources from the original Canadarm3 design toward broader lunar surface operations. MDA Space confirmed it will support the revised approach with updated robotic systems. The change aligns with evolving international plans for sustained presence on the Moon. Work will focus on technologies that can operate in the lunar environment for extended periods. Details on the new architecture are expected in coming months. Cosmic Spotlight The ALMA image of the trillion-mile gas streamer feeding GW Orionis reveals how material from a surrounding cloud can reach a young triple-star system and tilt its outer disk. The narrow stream stretches 0.2 light-years, delivering fresh gas that likely torques the planet-forming material out of alignment. This single observation shows external feeding can dominate disk evolution even after the initial collapse phase. Follow-up observations will track whether the streamer persists and how much mass it ultimately delivers. What fraction of other young systems experience similar external tilting events? Cosmic Deep Dive: How External Streams Tilt Young Star Systems A gas streamer 0.2 light-years long is roughly the distance from the Sun to the nearest star system beyond our own, yet it remains narrow enough that it could thread between two neighboring solar systems without touching either. Picture riding alongside one hydrogen molecule as it travels that entire length: it would take thousands of years at typical cloud speeds, all while staying confined within a channel only a few hundred astronomical units wide. ALMA’s radio observations show this channel is actively delivering fresh material into the GW Orionis system, where the incoming gas carries enough angular momentum to twist the outer disk. The mechanism works because the streamer arrives from a different direction than the original cloud core that formed the stars, so its momentum vector is misa

    Fascinating Frontiers 🚀 Fascinating Frontiers - Space & Astronomy News A Falcon 9 upper stage slammed into the Moon after drifting for a year, giving orbiters a live view of the impact flash and plume. Top 15 Space & Astronomy Stories ExoMars landing legs pass full-scale deployment test — ESA Activities Engineers at Thales Alenia Space in Turin tested the four landing legs that will support the ExoMars Rosalind Franklin rover platform in 2030. The legs deploy in two sequential pairs using non-explosive actuators in less than one second once the front shield separates. Each leg matches the flight article in size and structure and was built by Spain’s Sener. The test confirms the mechanism works after months of storage in deep space. Airbus supplies the landing platform while Sener designed and built the legs. Next, teams will integrate the legs with the full landing platform for combined parachute and engine descent trials. Webb reveals young star cluster inside Carina’s Treasure Chest — ESA Activities The James Webb Space Telescope imaged a cometary globule 7,500 light-years away in the Carina Nebula that contains roughly 70 young stars. The brightest member is an O-type star about 19 times the Sun’s mass, and the cluster is estimated at 1.3 million years old. Webb’s Near-Infrared Camera penetrated the surrounding dust to show circumstellar disks still embedded around many of the stars. Eta Carinae, 39 light-years northwest on the sky, supplies the intense radiation that helps shape the globule’s tail. The Treasure Chest spans part of the larger 260 light-year Carina Nebula, the nearest high-mass star-forming region in the galaxy. Follow-up observations are planned to track how the cluster’s outflows clear the remaining envelope. Confirmed Falcon 9 upper stage impact on Moon recorded by multiple spacecraft — Phys.org Space Scientists verified that the Falcon 9 second stage from the January 2025 lunar lander mission struck the lunar surface on August 5 as orbital models had forecast. The stage had spent more than a year in a high-energy Earth-Moon trajectory before solar activity and gravity pulled it into the Moon. Orbiting assets captured the impact flash and resulting plume, providing fresh data on surface composition through ejected material. This event marks one of the few documented cases of an uncontrolled lunar impact by a known spacecraft. SpaceX noted that for lunar transfer missions nearly all performance goes to payload delivery, so controlled disposal is not always possible. Analysts will compare the new crater and ejecta with earlier predictions to refine lunar impact models. New sharpest image of the Sun reveals magnetic instability — NASA Science The latest high-resolution solar image shows fine-scale magnetic structures that appear to drive rapid changes in the Sun’s surface. The observation captures instability in the magnetic field on scales smaller than previously resolved from the ground. Researchers are using the data to study how these features contribute to solar flares and coronal heating. The image was released as Astronomy Picture of the Day for August 6. NASA satellite tracks shifting tidal flats at Elbe River mouth — NASA Science Earth-observing instruments captured the dynamic movement of sediment and water at the German coastline where the Elbe meets the North Sea. The sequence shows how tidal cycles reshape exposed flats and maintain the busy shipping channel. Repeated passes allow scientists to measure sediment transport rates over time. NASA and Roscosmos extend crew seat exchange agreement — SpaceNews The two agencies will continue swapping seats on Soyuz and Crew Dragon flights to maintain continuous station presence. The new deal does not yet cover Boeing’s Starliner spacecraft. Both sides are still discussing how future commercial vehicles might fit into the barter system. Blue Origin traces New Glenn test explosion to BE-4 engine valve — SpaceNews Investigators determined that a valve inside the BE-4 engine caused the May static-fire failure of the New Glenn rocket. The finding points to a specific component rather than a broader design issue. Engineers are now addressing the valve design before the next test campaign. Diffuse gas plays major role in building massive stars — Phys.org Space Astronomers mapping the Monoceros R2 hub-filament system found that low-density gas surrounding dense filaments flows inward and replenishes the material available for star formation. Tracking the gas motions showed both direct inflow to the hub and indirect supply to the filaments themselves. The result indicates that earlier studies limited to dense gas alone may have underestimated the total mass budget for high-mass stars. Astronomers examine LHS 1140b for signs of habitability — mezha.net Researchers are analyzing new observations of the super-Earth LHS 1140b to assess whether it retains an atmosphere and liquid water. The planet orbits a nearby red dwarf and has been flagged as one of the most promising targets for atmospheric characterization. Further transit spectroscopy is scheduled with current facilities. Perseid meteor shower peaks August 12-13 — NASA Science The annual shower has been active since early July and will reach maximum on the night of August 12 into the morning of August 13. Observers worldwide can watch the display under dark skies, with rates expected to remain elevated through the end of August. NASA is providing viewing tips and live coverage. ISS transits active Sun in high-resolution photo — Astronomy An imager in China captured the International Space Station crossing the solar disk on August 1 next to sunspot groups AR4498 and AR4500. Software modeled the station’s path to time the 0.58-second transit precisely. The image shows the station’s silhouette against the active solar surface. Runaway supermassive black hole offers clues to ancient galaxy merger — Phys.org Space The object RBH-1 is racing through space after being ejected from its host galaxy, likely during a past merger event. Its trajectory and speed allow astronomers to reconstruct the dynamics of that earlier collision. Continued monitoring will help map the black hole’s path and any remaining bound stars. IXPE observations of magnetar test 90-year-old quantum prediction — NASA Science More than 140 hours of data from NASA’s IXPE mission on magnetar 1E recorded polarization signatures consistent with vacuum birefringence, a long-predicted effect of strong magnetic fields on empty space. The measurement marks the first direct indication of this quantum behavior in an astrophysical setting. Results appear in Nature. Little red dots may be pulsating massive stars in early universe — Phys.org Space James Webb images of compact red objects at high redshift are now being interpreted as possible monster stars rather than galaxies or black holes. Their pulsation properties could explain both their brightness and the formation of early supermassive black holes. Additional spectroscopy is underway to test the model. India positions space sector for expanded global partnerships — Awani International Government and industry leaders outlined plans to grow international collaboration in satellite manufacturing, launch services, and data applications. The strategy builds on recent successful missions and aims to attract more foreign investment and joint projects. Cosmic Spotlight The confirmed lunar impact of the Falcon 9 upper stage gave orbiting spacecraft an unplanned experiment on surface composition and ejecta dynamics. Spectral data from the plume already show sodium and lithium lines, matching earlier ground-based detections of similar events. Analysts will now compare the new crater size and brightness with models to improve predictions for future uncontrolled objects. The event also underscores how even spent hardware can still yield science when its trajectory is well known. What other dormant stages might future lunar orbiters catch in the act? Cosmic Deep Dive: How Diffuse Gas Feeds Massive Star Formation In the Monoceros R2 region, astronomers tracked gas flows across distances comparable to the width of a large terrestrial country, yet the material moves at only a few kilometers per second. Low-density gas that once seemed too thin to matter is now seen streaming inward, both directly toward the central hub and sideways into the dense filaments that already contain most of the star-forming cores. Over roughly a million years, this diffuse reservoir can supply enough mass to build stars ten or more times the Sun’s mass without requiring the filaments to grow solely by internal collapse. The measurements come from mapping velocity gradients across the entire hub-filament network rather than isolated dense peaks. The finding forces a re-evaluation of how much raw material is truly available in any given stellar nursery. The remaining puzzle is why some hubs convert this extra gas into stars efficiently while others appear to stall despite similar inflows. Fresh data keep rewriting what we thought we knew about how stars and planets assemble.

Results are under review at Space Weather. Source: phys.org Cosmic Spotlight Webb’s aperture-masking observations of Io captured surface details at scales previously limited to flyby spacecraft. The mask turns the telescope into an interferometer by sampling light through discrete pinholes, then recombining the beams to reconstruct finer structure. This approach bypassed the glare of Jupiter while resolving volcanic hotspots and plume deposits. The same mode also mapped dust gaps around PDS 70, showing where planets are clearing material. Next, teams will apply the technique to additional targets during upcoming visibility windows. How small a feature on a distant exoplanet moon might this method eventually reveal? Cosmic Deep Dive: How Aperture Masking Turns a Telescope into an Interferometer Picture a 6.5-metre mirror reduced, for a few minutes, to a handful of coin-sized openings spaced metres apart; the light that passes through those openings travels separate paths yet still interferes at the detector as though the entire mirror had been used at once. Riding alongside one photon, you would see it take one pinhole route while its twin takes another, the two waves arriving with a tiny delay that encodes the exact angular separation of the source. That delay is measured in fractions of a wavelength, letting the instrument resolve details ten times finer than the telescope’s normal diffraction limit. On Io the technique isolated individual volcanic vents separated by only tens of kilometres; on PDS 70 it traced gaps in the protoplanetary disk narrower than the orbit of Jupiter. Yet the same mask also discards most of the starlight, so exposure times stretch and faint targets remain out of reach. The open question is whether future masks with hundreds of pinholes, paired with advanced wavefront sensing, can push the resolution even closer to the theoretical maximum set by the mirror diameter itself. New data keep reshaping how we read the solar system’s ongoing story.

The contrast between personal names and the vast survey volume underscores how exploration missions still carry human stories alongside their instruments. What new worlds will those names effectively travel past once Roman begins its infrared census? Cosmic Deep Dive: Zodiacal Dust Beyond Our Solar System Picture a faint band of light stretching across the predawn sky, visible only when you stand in the darkest desert; that same glow, scaled up, could surround countless other stars. In our solar system the band is produced by countless microscopic grains, each roughly the size of a grain of sand, drifting in the plane of the planets and lit by sunlight. Around another star the same dust would lie within a few astronomical units of the host, orbiting at speeds of tens of kilometers per second and replenished by collisions among unseen asteroids or comets. One surprising measurement already in hand is that the total mass of this warm dust around some nearby stars can reach several times the mass of our own zodiacal cloud, enough to outshine the star itself at certain infrared wavelengths. When astronomers try to photograph an Earth-like planet in that system, the dust scatters starlight into the same pixels, creating a glare that can swamp the planet’s own faint signal. The open question is whether this dust is steadily ground down and removed or whether fresh collisions keep the haze dense for millions of years; we can measure the brightness, but we still do not know which process dominates. New instruments and fresh sky covera

Coronagraphic techniques suppressed the host star’s light to reveal the companion. Additional epochs are planned to track orbital motion and refine mass estimates. Webb Finds Warp in TW Hydrae Protoplanetary Disk — Phys.org Space High-contrast coronagraphic images from JWST reveal a clear warp in the disk surrounding the young star TW Hydrae. The distortion appears in the inner regions where planets are thought to form. Published results on arXiv show the warp’s geometry and suggest possible causes such as an unseen companion or recent dynamical interaction. The nearby system allows detailed study of disk evolution at scales comparable to our own solar system’s early stages. Follow-up observations will search for embedded planets that may be driving the asymmetry. Super-Earth Shows Possible Atmospheric Signature — KSL News Observations of a super-Earth exoplanet indicate the presence of an atmosphere through transmission spectroscopy. The data suggest the world retains a gaseous envelope despite its proximity to its star. This finding adds to the small sample of rocky planets with detectable atmospheres. Further transit measurements are needed to identify specific molecular species. The result supports continued efforts to characterize atmospheres on worlds larger than Earth but smaller than Neptune. Talon A Hypersonic Vehicle Completes Tenth Flight — Space.com RSS Stratolaunch’s Talon A autonomous vehicle has now flown more than ten times after its latest air-launched test. The craft reaches speeds near Mach 5 during each mission. Data collected during the flights refine guidance and thermal protection systems.

The facility includes a simulated launch experience and displays of hardware models. City officials expect the center to support public education and industry outreach. Construction wrapped ahead of the public opening this month. The venue joins other regional efforts to highlight China’s growing space program. Cosmic Spotlight The Falcon 9 upper stage impact offers a controlled experiment on the lunar surface. Orbiters will measure the flash, seismic waves if detectable, and the fresh crater morphology. Pre-impact imaging already exists, so the difference will be immediate. Scientists expect the event to expose subsurface material at a new location. How much ejecta reaches escape velocity remains an open measurement. Cosmic Deep Dive: Warped Protoplanetary Disks A protoplanetary disk around a young star like TW Hydrae can stretch more than 100 times the Earth-Sun distance yet still show a distinct bend within the inner few dozen astronomical units. Picture a vast, spinning plate of gas and dust the width of a major city’s metropolitan area; now tilt just the central dinner-plate-sized region by several degrees. That tilt can arise when an unseen planet or stellar companion gravitationally tugs one section of the disk out of alignment with the rest. JWST’s recent coronagraphic images captured exactly this geometry around TW Hydrae, revealing the warp through scattered starlight at near-infrared wavelengths. The structure matters because it can funnel material inward or outward, changing where planets ultimately form and how much gas they accrete. The open question is whether such warps are common signposts of forming planets or whether they trace rarer dynamical

Source: space.com Solar Wind Directly Strips Particles from Mars’ Upper Atmosphere — Phys.org Space Without a global magnetic field, Mars allows the solar wind to interact with its thin upper atmosphere. Charged particles from the Sun collide with atmospheric atoms and accelerate some of them to escape velocity. New observations quantify how this process varies with solar activity. The findings help refine models of how Mars lost most of its original atmosphere over billions of years. The measurements track ion escape rates across different solar wind conditions to improve long-term atmospheric loss estimates. Source: phys.org Cosmic Spotlight NASA’s new 3D geoid model reveals that Earth’s gravity field creates a lumpy ocean surface rather than a perfect sphere. Satellite measurements show sea level can differ by tens of meters depending on location because of uneven mass distribution beneath the crust. The interactive tool lets anyone explore how these gravitational variations affect everything from satellite orbits to ocean currents. What local gravity feature would you most like to see mapped in higher resolution next? Cosmic Deep Dive: How the Solar Wind Steals Mars’ Atmosphere Imagine a stream of charged particles 400 kilometers wide hurtling past Mars at 400 kilometers per second, crossing the distance from New York to Los Angeles in roughly ten seconds. That flow is the solar wind, an unbroken outward current from the Sun. Mars offers no global magnetic shield, so the wind collides directly with the upper atmosphere. Ions form when solar particles strip electrons from atmospheric atoms; the embedded magnetic fields then sweep those ions away like debris caught in a fast current. Data from recent spacecraft show escape rates rise sharply during solar storms when the wind carries extra energy and density. Models still cannot account for why certain atmospheric layers lose material at rates higher than expected even under steady solar wind conditions. The central puzzle remains whether early Mars possessed a thicker envelope that the solar wind slowly eroded or whether other processes first thinned the atmosphere before the wind took over. Space keeps revealing new layers of its workings every day.

    Fascinating Frontiers 🚀 Fascinating Frontiers - Space & Astronomy News Astronomers have detected the first exomoon, opening a new window on how satellites form beyond our solar system. Top 15 Space & Astronomy Stories Astronomers Detect First Exomoon Candidate — WIRED The candidate orbits a planet or brown dwarf roughly 12 times the mass of Jupiter. Detection relied on transit timing variations and gravitational microlensing signatures captured over multiple epochs. No named instrument is specified in the report, though ground-based surveys supplied the photometry. The find challenges standard moon-formation models because the moon’s inferred mass and separation sit outside expected ranges for both in-situ accretion and capture. Follow-up observations with larger telescopes are planned to confirm the signal and refine the mass ratio. Asteroid Nysa Appears as Three-Lobed Body — Universe Today Sharp images from two large Earth-based telescopes show two deep valleys encircling the 75-kilometre object. Researchers interpret the valleys as contact necks linking three separate lobes. A previously unknown kilometre-scale moon was also detected in the same data set. If confirmed, Nysa would be the first known three-lobed minor planet. Additional light-curve and radar observations are needed to test the rubble-pile interpretation. The same observations revealed the tiny companion moon that may help settle the structural debate. Neptune’s Inner Moons and Rings Built from Smashed Ice Worlds — Universe Today Triton’s capture is thought to have disrupted an earlier satellite system whose fragments now form the dusty rings. The study models how larger precursor moons were shattered and re-accreted into the current small inner satellites. Remnant material supplies the observed ring mass. The work uses N-body simulations tuned to match the present orbital architecture. Future missions carrying dust analyzers could test the predicted ice compositions. Triton itself accounts for more than 99.5 percent of the mass among Neptune’s sixteen known moons. Charon’s Mountains Hint at Faster Past Rotation — Universe Today New Horizons flyby data revealed tectonic features on Pluto’s largest moon. Models indicate Charon once spun roughly ten times faster than its current synchronous rate. The rapid spin would have generated stresses sufficient to fracture the crust and raise the observed mountain ranges. The moon’s mass is one-eighth of Pluto’s, the highest satellite-to-planet ratio in the solar system. Further mapping of fault orientations could tighten the spin-down timeline. Charon’s diameter reaches half that of Pluto, underscoring its unusual scale. Nuclear Rockets Explored for Interstellar Distances — Universe Today Concepts under discussion include nuclear thermal and nuclear electric propulsion systems. These designs aim to shorten travel times to the nearest stars from millennia to centuries. The article reviews propellant heating cycles and reactor mass budgets but supplies no specific thrust or specific-impulse figures. No principal investigator is named. Ground testing of reactor components remains the next engineering milestone cited. The review places these ideas in the broader context of achieving practical interstellar flight with current technology limits. August Skywatching Features Eclipses and Perseids — NASA Science Observers can watch a solar eclipse, a deep partial lunar eclipse, and the Perseid meteor shower. Venus reaches peak evening brightness during the same period. The agency’s monthly guide lists optimal viewing times by longitude without providing instrument requirements. No specific magnitude or rate predictions appear in the release. Public outreach events are scheduled at several NASA centers. The Perseids stand out as one of the year’s most reliable annual showers. LINK Spacecraft Spin Slowed for Swift Orbit Boost — NASA Science Katalyst Space teams continue to reduce the spacecraft’s rotation rate. LINK is intended to raise the orbit of NASA’s Swift observatory. Progress is reported through ground-station telemetry but no numerical spin-rate values are given. The mission remains in the stabilization phase. No revised timeline for the boost maneuver is supplied. Swift itself continues routine ultraviolet and X-ray observations while awaiting the potential altitude adjustment. AI Identifies Seven New Quasar Lenses — Space.com The candidates were found by training algorithms on wide-field imaging to spot multiple images of background quasars. Each system is gravitationally lensed by a foreground galaxy, stretching spacetime on arcsecond scales. The sample expands the known set of quasar lenses useful for measuring black-hole growth and galaxy evolution. No individual lens redshifts or magnifications are listed. Spectroscopic confirmation with large telescopes is the immediate follow-up step. These rare alignments offer direct probes of how supermassive black holes and their host galaxies co-evolve. Moonquakes Could Expose Buried Polar Ice — Phys.org Space Seismic waves from natural or artificial sources may travel through ice layers beneath south-polar craters. The study calculates that ice deposits several metres thick would produce distinct reflection signatures. No specific quake magnitudes or frequencies are provided. Future landers carrying seismometers could map ice extent without drilling. The approach avoids direct sampling hazards in permanently shadowed regions. Detecting these vibrations could confirm water ice presence at depths otherwise inaccessible to surface instruments. New Maps Quantify Martian Subsurface Ice — Phys.org Space Global water-ice maps combine orbital neutron data with statistical confidence intervals. Two papers from the Planetary Science Institute outline where ice is probable near proposed human landing sites. No absolute ice-mass values are stated. The work identifies instruments needed to raise map certainty above current thresholds. Landing-site planners can now prioritize zones with higher ice probability. The maps integrate neutron spectrometer readings from multiple orbiters to constrain ice depth and distribution. IC 1101 Confirmed as Largest Known Galaxy — arXiv (via Reddit summary) Deep imaging reached the galaxy’s outer edge for the first time. The measured stellar extent is 520 kiloparsecs, equivalent to roughly 1.7 million light-years. Total stellar mass is estimated at 3.4 trillion solar masses. The observations used large ground-based telescopes under excellent seeing. No follow-up survey plans are mentioned. This size places IC 1101 well beyond previous records for galactic diameter and stellar content. Repurposed Mars Rover to Moon Could Cost Over $1 Billion — SpaceNews An engineering model of a Mars rover is under consideration for lunar surface operations. NASA’s administrator rejected the cost estimate as too high. No breakdown of subsystems or launch-vehicle expenses appears in the report. The agency has not released an alternative budget figure. Concept studies continue at lower fidelity. The engineering model in question originated from earlier Mars rover development programs. NASA Langley Opens New Wind Tunnel — NASA The Flight Dynamics Research Facility began operations on July 31. It is the first major wind tunnel at the center in more than 40 years. The facility will test aircraft, rockets, and exploration vehicles. No test-section dimensions or maximum speeds are given. Virginia government officials attended the ribbon-cutting. The new tunnel supports research into vehicle performance across a range of speeds and configurations critical for future missions. Oxford Team Finds Ultra-Low-Density Giant Planets — 동아사이언스 The planets have densities lower than cotton candy. Discovery used transit photometry and radial-velocity follow-up. No masses, radii, or host-star names are supplied in the English-language summary. The low densities imply extended hydrogen-helium envelopes. Additional atmospheric characterization observations are expected. Such extreme fluffiness challenges conventional models of giant-planet formation and migration. Tabby’s Star May Host Giant Planetary Companion — Phys.org (via Reddit) A new analysis suggests a body nine times Jupiter’s mass and 1.7 times its radius. The candidate is distinct from the known red-dwarf binary companion. The signal appears in archival photometry and radial-velocity data. No orbital period is stated. Further monitoring is required to confirm the long-period orbit. The proposed companion would rank among the most massive objects detected around this famously variable star. Cosmic Spotlight The three-lobed shape proposed for asteroid Nysa would make it the first known contact body with two distinct necks. The valleys visible in the new telescope images run completely around the 75-kilometre object, suggesting the lobes never fully merged after a gentle collision. A kilometre-scale moon discovered in the same data set may have helped stabilize the unusual configuration through tidal interactions. If rubble-pile models hold, Nysa preserves a record of early solar-system collisions that most asteroids have since lost. The next step is targeted radar or spacecraft flyby imaging to measure the internal density distribution. How did three separate lobes remain intact instead of collapsing into a single sphere? Cosmic Deep Dive: How Rubble-Pile Asteroids Resist Catastrophic Breakup Picture a city-sized pile of gravel and ice drifting between Mars and Jupiter; if every fragment were scaled to the size of a suitcase, the whole asteroid would still span dozens of kilometres yet contain more empty space than solid rock. When two such loosely bound objects meet at walking speed, the impact energy dissipates through rearrangement of the fragments rather than explosive fragmentation, allowing the pieces

Source: science.nasa.gov Mercury’s Magnetic Field Traps Solar Wind — Universe Today Mercury’s weak magnetic field periodically captures and funnels solar wind particles toward the surface. The field was first detected in 1974 and continues to surprise researchers given the planet’s small size. Data show the field creates temporary trapping regions rather than a steady shield. These interactions differ from Earth’s more robust magnetosphere. Future orbiter measurements will map the variability in greater detail.

Experts recommend developing safety protocols before the first systems reach orbit. The article notes gaps in current licensing frameworks for non-traditional payloads. Early coordination could reduce later conflicts with existing operators. Industry and regulatory groups are beginning preliminary discussions. Source: spacenews.com Cosmic Spotlight Astronomers used the James Webb Space Telescope to probe binary stars inside the Small Magellanic Cloud, a nearby galaxy with far fewer heavy elements than the Milky Way. Lower metallicity changes how stars lose mass and transfer material, producing different evolutionary paths than those seen locally. The observations target young pairs still surrounded by gas and dust, giving direct views of early interaction stages. Results will test whether binary fractions and mass ratios scale with a galaxy’s overall metal content. What fraction of these systems will ultimately merge or produce exotic remnants remains an open question. Cosmic Deep Dive: How Low Metallicity Reshapes Binary Star Lives If the Sun formed inside a galaxy like the Small Magellanic Cloud, it would have started with only one-fifth the iron and other heavy elements we measure today. That scarcity changes everything about how a star sheds its outer layers and how two stars in a pair exchange mass. In metal-poor gas, stellar winds are weaker, so stars retain more mass until they expand and fill their Roche lobes. A typical close binary might then transfer material at rates ten times higher than equivalent Milky Way pairs, driving rapid spin-up or even envelope ejection on timescales of just a few hundred thousand years. We can watch the outcome in ultraviolet and infrared light, yet we still cannot predict whether the same low-metal conditions produce more neutron-star mergers or more stripped-envelope supernovae. The unanswered piece is whether these altered pathways also change the final compact-object mass distribution in ways that affect gravitational-wave signals we detect from across the universe. Stars and stellar remnants already account for the vast majority of a galaxy’s baryonic mass, so shifts in binary outcomes could reshape how entire galaxies evolve over cosmic time. The Small Magellanic Cloud therefore serves as a living laboratory where astronomers can compare metal-poor pathways against the metal-rich systems we know best in the Milky Way. New observations continue to refine how we track everything from nearby planets to distant binaries.
