These compact, unusually hot objects challenge standard models of stellar evolution. The team’s approach improves detection rates and highlights new candidates for follow-up spectroscopy. Phys.org Space summarized the ongoing investigation. The work focuses on explaining the high temperatures observed in these compact stars. Perseverance images Earth occulted by Phobos — Phys.org Space NASA’s Perseverance rover recorded a sequence in which Earth passes behind the Martian moon Phobos. The frames show Earth as a bright point disappearing behind the moon’s crescent limb. The observation demonstrates the rover’s ability to capture precise timing events from the Martian surface. Phys.org Space published the image set. The images provide a unique perspective on the relative motions of Earth and Phobos as seen from Mars. Lunar occultations of planets and stars approach in September — Universe Today The Moon will pass in front of Jupiter, Venus, bright stars, and an open cluster during the coming weeks. Observers on Earth can watch these events from different longitudes depending on local timing. The article lists visibility windows and notes that the Harvest Moon on 26 September follows the series. Universe Today provides the schedule for each target. The events allow precise measurements of lunar motion and stellar positions. New 1666 manuscript may document Galileo’s early telescope work — Phys.org Space A University of Limerick researcher identified technical details in a previously unexamined manuscript that appear to describe four-lens telescope experiments. The document could represent the earliest known technical record of an instrument built by Galileo. Further study will compare the described optics with surviving historical examples. Phys.org Space reported the discovery. The manuscript offers new insight into the development of early astronomical instruments. Penultimate set of lunar occultations readies for September — Universe Today Multiple bright celestial objects will be hidden by the Moon before the Harvest Moon arrives later in the month. The geometry offers last opportunities in the current season for timing measurements from ground-based telescopes. Observers are encouraged to record video or visual timings where weather permits. The article supplies predictions for each event. Ground teams can use the alignments to refine orbital data for the Moon. Cosmic Spotlight The transformation of a distant centaur into an active comet offers a direct view of how ice sublimation begins far from the Sun. Observations show the sudden appearance of a coma around an object that had previously shown no activity. This stage bridges the gap between inert Kuiper-belt bodies and the more familiar short-period comets that reach the inner solar system. Continued monitoring will reveal whether the activity persists or fades as the object moves outward again. The event occurred roughly three billion miles from the Sun. What triggers the initial release of volatiles in objects at such great distances remains an open question. Cosmic Deep Dive: How Small Orbital Perturbations Activate Distant Icy Bodies An object the size of a modest city drifting three billion miles from the Sun can shift its closest solar approach by only a few million kilometres after a single gravitational encounter with a giant planet. That tiny adjustment lifts surface temperatures just enough for trapped ices to begin turning directly into gas. The released material expands into a visible coma that radiation pressure quickly stretches into a tail hundreds of thousands of kilometres long. Rotation focuses the heating on one face at a time, so the outburst can appear within weeks rather than over an entire orbit. We still cannot explain why two centaurs on nearly identical paths will behave differently, with one suddenly brightening while its neighbour stays dark through repeated close passages. The precise trigger that decides which bodies activate and which remain inert continues to puzzle observers. New observations continue to refine our picture of how small bodies evolve across the solar system.

Mercury’s Crust Linked to Extreme Early Volcanism — Universe Today Researchers used lunar sample data to model how silicon dioxide abundance reveals volcanic styles on ancient Mercury. High SiO2 levels point to rapid, high-temperature eruptions that built much of the planet’s crust. The approach allows scientists to compare volcanic histories across terrestrial worlds without new samples from Mercury. The study refines understanding of how small planets differentiate. Follow-up papers will apply the same method to other bodies. Sounding Rocket Flies Through Sporadic E Layer — Phys.org Space A NASA sounding rocket carried five detectors through a metallic haze layer created by vaporized meteor dust. The simultaneous measurements revealed unexpected fine-scale structure inside the layer. Sporadic E clouds can disrupt radio signals and GPS. The flight provided the first multi-point view of how these layers form and dissipate. Scientists will use the data set to improve ionospheric forecast models. Young Sunlike Star Shows Signs of Exocomets — Phys.org Space Astronomers at Lund University detected evidence of comets orbiting a young star similar to the Sun. The observations suggest these bodies could deliver water to the inner regions where planets are forming. The star’s age places it in a phase when planetary systems are still assembling. Spectral signatures indicate volatile material is being transported inward. Continued monitoring will track how often such events occur. Hubble Spots New Ten-Sided Wave at Saturn’s South Pole — Phys.org Space Recent Hubble images show a giant, evolving, ten-sided atmospheric wave circling Saturn’s south pole.

The wave’s regular shape offers a fresh laboratory for studying giant-planet atmospheric dynamics. Additional observations are planned during upcoming oppositions. Cluster Spacecraft Reentry Yields Reentry Data Set — Phys.org Space The final Cluster satellite, Tango, reentered on September 1 after targeted maneuvers. Scientists aboard an aircraft recorded the breakup in detail, creating a unique data set on satellite demise. The campaign tested safe end-of-life disposal techniques for future missions. Data will inform designs that reduce debris and improve atmospheric reentry predictions. Four targeted reentries across the Cluster fleet provided repeated observation opportunities. Cosmic Spotlight The HASP balloon campaign’s twentieth flight demonstrates how student-built instruments can reach the edge of space on a regular cadence. Payloads tested new sensors under near-vacuum conditions that ground labs cannot fully replicate. The six-hour-and-forty-five-minute float at 122,000 feet gave teams real flight heritage data they can cite in future proposals. This steady access helps bridge the gap between university projects and professional missions. What experiment would you design if you had a seat on the next HASP flight? Cosmic Deep Dive: How Meteoric Dust Builds Temporary Radio Shields Picture a single meteor the size of a grain of rice streaking through the upper atmosphere at 70 kilometers per second; in the span of a heartbeat it vaporizes and releases a few grams of metal atoms that spread into a thin horizontal sheet roughly the area of a large city. Those atoms collide with air molecules, lose electrons, and form a patchy layer of ions and electrons between 90 and 120 kilometers up—exactly where shortwave radio and GPS signals pass. The layer can appear in minutes and vanish in hours, yet while it lasts it can reflect or absorb radio waves the way a temporary mirror blocks a flashlight beam. One surprising number keeps appearing in the measurements: the electron density inside these sporadic E clouds can reach 100,000 electrons per cubic centimeter, high enough to bend signals that would normally travel straight through. We can map the patches with rockets and radar, but nobody yet knows why the metal atoms sometimes clump into neat, long-lived sheets instead of simply diffusing away. Space keeps delivering fresh data and fresh questions every single day. ```claims []

Simulations Suggest Moon Could Form Intact in Hours After Giant Impact — Phys.org Space Southwest Research Institute modeling incorporates material strength during the Earth-Moon forming collision. The calculations indicate an intact lunar body could assemble within roughly five hours. Earlier models without strength effects produced different outcomes. The new results may help narrow the timing of the impact event. Follow-on studies will test the findings against lunar sample data. Saturn Flyby May Have Activated Distant Centaur Object — Phys.org Space Centaur 450P/LONEOS has begun releasing gas and dust after a gravitational encounter with Saturn. The object orbits between Jupiter and Neptune yet now shows comet-like behavior. The activation occurred more than three billion miles from Earth. Observations track the developing coma and tail. Continued monitoring will reveal how long the activity persists. Precision Optics Prepared for ESA Plant-Fluorescence Mission — Phys.org Space Fraunhofer IOF delivered a silicon-based double-slit assembly and two high-precision mirrors for the FLEX spectrometer. The satellite is scheduled for launch on September 15, 2026. From orbit the instrument will measure sunlight-excited fluorescence from vegetation. The data will indicate photosynthetic activity and plant stress levels. Calibration of the optics is now complete. Study Maps Seven Stages of Meteorite Atmospheric Entry — Space.com Researchers examined 75 observed falls to identify the sequence of physical changes. The stages span initial heating, fragmentation, and final deceleration. Each phase leaves distinct signatures in recovered fragments. The work improves models used to predict ground impact locations. Additional falls will test and refine the framework. ASTRID Cosmological Simulation Reaches Present-Day Universe — Universe Today The ASTRID run models structure formation from the early universe to z=0 with high particle counts. Its resolution allows tracking of black-hole mergers that future gravitational-wave observatories may detect. The simulation volume sits between smaller high-resolution runs and larger lower-resolution ones. Output catalogs are now available for the community. Analysts will use the data to guide observing strategies. Cosmic Spotlight The ASTRID simulation supplies a high-resolution view of how supermassive black holes grow through repeated mergers across cosmic time. Its particle count lets modelers follow individual merger events that produce the gravitational-wave signals future detectors will record. Because the run extends to the present day, researchers can compare predicted merger rates against current electromagnetic surveys of active galactic nuclei. The data also highlight which galaxy environments host the most frequent coalescences. Next, teams will cross-match ASTRID outputs with upcoming LISA sensitivity curves to forecast detection rates. Cosmic Deep Dive: How Gravity Turns Distant Icy Wanderers into Active Comets Picture an object the size of a small mountain drifting in the cold between Jupiter and Neptune; if you could stretch a measuring tape from Earth to that body, the distance would equal roughly 4.8 billion kilometers, or more than thirty times the span from here to the Sun. That vast separation keeps the surface frozen solid for billions of years until a rare close pass by Saturn rearranges its orbit and drops it inward. Once the distance to the Sun shrinks enough for sunlight to warm the ices, trapped gases begin to sublimate, lifting dust and creating the hazy envelope we recognize as a comet's coma. The transition can unfold over months rather than years because the thermal pulse travels only meters into the porous surface before vapor pressure overcomes the weak gravity. Yet the precise trigger—whether it is the first warming cycle or cumulative effects from earlier distant encounters—remains unknown, leaving observers to wonder why some centaurs awaken while others stay inert at the same distance. Space keeps delivering fresh puzzles alongside steady progress on long-running missions.

Melinda French Gates Recalls Apollo-Era Engineers — The Times of India Her father worked on NASA’s Apollo missions and hosted women engineers at company picnics. Those encounters shaped her later views on technical careers and inclusion. The article highlights how early exposure to aerospace professionals influenced her perspective on opportunity and mentorship. No new technical details about the Apollo program are provided. Mars Interior Shows Strong Hemispheric Heat Difference — Universe Today The southern hemisphere remains roughly 400 °C hotter at depth than the north. This contrast reflects the planet’s early cooling history and the loss of its global magnetic field. The warmer southern interior once drove widespread volcanism that helped sustain a thicker atmosphere. Today the difference helps explain why certain surface features and crustal thicknesses vary between hemispheres. Future orbiters and landers may map heat flow more precisely to test these models. Black Hole Observed Ejecting Material After Stellar Meal — Universe Today Astronomers captured a black hole expelling matter shortly after consuming a star. The event offers a rare view of the post-accretion phase that remains poorly understood. Jets and outflows appear once the initial flare subsides, yet the exact trigger for ejection is still unclear. Continued monitoring should reveal how much material escapes versus how much stays bound. Iceberg From Petermann Glacier Survives Island Collision — NASA Science A large iceberg calved in summer 2026 and drifted into Nares Strait. It struck Joe Island yet remained intact enough to continue moving. Satellite imagery tracked the berg’s path and the deformation caused by the impact. Such events help refine models of iceberg breakup and their contribution to freshwater input in Arctic waters. Physicist Explores the Universe’s Arrow of Time — Universe Today Jim Al-Khalili’s new book “On Time” examines why time appears to move in only one direction. The discussion connects thermodynamics, quantum mechanics, and cosmology to the everyday experience of time’s flow. No experimental results are presented; the work synthesizes existing arguments. Readers interested in foundational questions will find the treatment accessible. Binary Stars Complicate Search for Earth-Analog Planets — Phys.org Space Roughly half of sun-like stars near us have at least one companion. These companions stir orbital dynamics and can truncate or destabilize the habitable zones where Earth-like worlds might form. The article notes that current detection methods must account for the gravitational influence of both stars. Improved modeling and longer observation baselines are needed to identify stable orbits in such systems. Swift Telescope Resumes Observations After Rescue Attempt — Space.com NASA’s Swift observatory has restarted science operations following an unsuccessful private mission to raise its orbit.

Türkiye Joins Artemis Accords as 71st Signatory — Latest news from Azerbaijan The Republic of Türkiye signed the accords during a ceremony at NASA headquarters. The agreement commits signatories to peaceful, transparent exploration principles. No immediate mission assignments for Turkish hardware were announced. New Memory-Centric Chip Architecture Proposed for Deep Space — telecomreviewafrica.com Researchers describe processors that keep data closer to compute elements to reduce power and latency. Radiation tolerance remains a key requirement for any flight hardware. The approach could benefit long-duration missions where bandwidth back to Earth is limited. Cosmic Spotlight Mars’s southern hemisphere sits hundreds of degrees hotter at depth than the north, a difference rooted in how the planet cooled after its formation. That retained heat once powered widespread volcanism and helped maintain a thicker atmosphere and magnetic field. Today the contrast influences crustal thickness and the distribution of ancient river valleys. Future heat-flow measurements from landers or orbiters could test whether the asymmetry dates back to a single giant impact or to uneven mantle convection. What would a global map of present-day heat flow reveal about the last stages of Mars’s internal activity? Cosmic Deep Dive: Light’s Long Journey Across the Universe Picture a single photon leaving a galaxy when Earth’s first continents were still forming; by the time it reaches our telescopes the continents have drifted thousands of kilometers and countless civilizations have risen and fallen. That photon has traveled for more than ten billion years, crossing roughly 100 billion trillion kilometers, yet it arrives carrying an unaltered record of the conditions when stars were just beginning to ignite. Along the way the universe itself expanded, stretching the photon’s wavelength from ultraviolet into the infrared we now detect with instruments like JWST. We can measure its spectrum, count its companions from the same ancient galaxy, and reconstruct the density of matter at that moment, but we still cannot explain why the expansion rate appears slightly different depending on whether we measure nearby or very distant objects. The mismatch hints that either our distance ladder or our understanding of early-universe physics is incomplete. What hidden property of space or matter might reconcile these two views of the same cosmic timeline? Space exploration keeps revealing both the machinery of the cosmos and the practical steps still required to explore it further.

The concept would create a specialized pipeline separate from existing service academies. Proponents cite growing demand for space-domain expertise. Skeptics question whether a new institution is necessary given current training programs. The discussion centers on curriculum focus and long-term force structure needs. Seven-Stage Model Maps Meteor Atmospheric Survival — Universe Today Researchers have outlined a seven-stage sequence describing how space rocks decelerate and fragment during atmospheric entry. The model incorporates ablation rates, fragmentation thresholds, and terminal velocity calculations. It allows better estimates of ground impact energy and strewn-field patterns. Validation draws on recovered meteorites and eyewitness reports. The framework is now being tested against recent well-observed fireballs. Australian CubeSat Trio Scheduled for Late 2026 — space & defense The Binar-567 mission, consisting of three CubeSats, is slated for launch in the fourth quarter of 2026. The spacecraft will conduct technology demonstrations and educational outreach from low Earth orbit. Project teams at Curtin University have completed integration and environmental testing.

The setup reached magnetic intensities higher than earlier permanent-magnet experiments. Results will guide development of magnetohydrodynamic aerobraking systems for reusable spacecraft. The platform operates at speeds above seven kilometers per second. Future tests aim to scale the technology toward flight hardware. Cosmic Spotlight ESA’s JUICE spacecraft will pass within a few thousand kilometers of Kallichore, one of Jupiter’s irregular satellites that has remained largely unchanged since the solar system’s formation. The moon’s dark surface and distant orbit suggest it may be a captured object whose composition preserves primordial ices and organics. JUICE’s suite of cameras, spectrometers, and particle detectors will gather data during the brief encounter, offering the first close look at this class of body. The observation complements the mission’s primary focus on the icy Galilean moons while adding context to how Jupiter assembled its retinue of satellites. Scientists will compare the results with ground-based surveys to refine models of outer-planet satellite capture. What surface features or compositional clues will the flyby reveal that current telescopes cannot detect? Cosmic Deep Dive: Meteor Atmospheric Survival A typical meteoroid the size of a grapefruit can cross an entire continent in under ten seconds while traveling at 20 kilometers per second. Picture riding alongside that rock as it first strikes the upper atmosphere: friction instantly heats the leading face to thousands of degrees, vaporizing surface layers in a glowing sheath of plasma. Within the next few seconds the object experiences peak dynamic pressure that can exceed ten times the force needed to crush granite, triggering fractures that split the body into dozens of fragments. Some pieces ablate completely; others decelerate enough to drop below supersonic speeds and fall as dark flight. The entire sequence lasts less than half a minute yet records temperatures, pressures, and chemical reactions impossible to replicate fully in ground laboratories. We can now predict roughly where fragments land, but the precise moment when a given rock will break apart still depends on internal flaws we cannot measure before entry.

Source: reddit.com Cosmic Spotlight Scientists have now melted diamond in the lab to simulate the interiors of Neptune and Uranus. The work shows how carbon can condense into crystals that rain through layers of compressed ice and rock. The same process may explain why these planets release more heat than they receive from the Sun. Next tests will track how the falling diamonds affect convection and magnetic field generation inside the worlds. Cosmic Deep Dive: Diamond Rain Inside Ice Giants Neptune’s mantle reaches pressures roughly two million times higher than the deepest point in Earth’s oceans, a force that would crush any familiar material into new forms. Picture riding inward with a carbon atom as surrounding water and ammonia squeeze tighter with every kilometer; at a certain depth the carbon atoms link into rigid lattices and drop like microscopic hail. Laboratory lasers have now reproduced that exact pressure spike for a few billionths of a second, long enough for diamond crystals to nucleate and begin their slow descent. The crystals are thought to reach sizes of centimeters before dissolving again near the core, releasing gravitational energy that helps power the planet’s surprisingly strong magnetic field. Yet models still cannot explain why Neptune radiates almost three times more heat than it absorbs from the Sun. The mismatch suggests either an unknown heat source or a flaw in how we picture the rain’s efficiency. Future missions carrying seismometers or atmospheric probes could settle the question by measuring the actual rate at which diamonds are forming and falling. Laboratory recreations also raise the possibility that similar carbon behavior occurs inside exoplanets of comparable mass and composition, opening a new window on worlds we can only observe from afar. The timing of crystal formation versus dissolution remains uncertain, leaving open whether the process operates continuously or in episodic bursts tied to internal convection cycles. Space keeps revealing new ways matter behaves under extremes we can only touch briefly on Earth.

The project focuses on extraterrestrial biomanufacturing techniques that could support long-duration missions by generating food, pharmaceuticals, or construction materials on site. Researchers aim to understand how altered gravity and radiation environments affect cellular processes used in production. The collaboration builds on existing Canadian expertise in space biology and seeks to develop closed-loop systems that reduce reliance on resupply from Earth. Next steps include ground-based simulations followed by potential experiments on the International Space Station. The work draws on the lab’s prior studies of cellular responses to space conditions. Canadian Space Agency support will help translate ground findings into flight-ready hardware. Results could inform how future crews sustain themselves without constant cargo deliveries. MIT team wins first prize in NASA LunaRecycle Challenge Phase 2 — NASA Breaking The Composites for Extraterrestrial Recycling By Engineering the Reuse and Upcycling of Zotek (CERBERUZ) team from MIT received $775,000 for its system that converts mixed waste into reusable powder. The approach grinds fabrics, plastics, foam, and metals into a fine material that can be reformed into new parts or structures during lunar or deep-space missions. NASA designed the challenge to address the growing problem of waste accumulation on long-duration flights where every kilogram of trash must be managed without return to Earth. The winning technology emphasizes upcycling rather than simple disposal, turning discarded items into feedstock for additive manufacturing. The CERBERUZ team includes undergraduate, graduate, and doctoral students at MIT. Follow-on work will test the process in relevant environments to refine particle size and material properties. The award reflects NASA’s priority on sustainable logistics for crews operating far from Earth. Jeremy Hansen receives U.S. Space Medal of Honor as first non-NASA recipient — The Lethbridge Herald Canadian astronaut Jeremy Hansen was awarded the Congressional Space Medal of Honor for his role on the Artemis II crew that flew around the Moon. The honor marks the first time the medal has gone to someone outside NASA’s astronaut corps.

The new vehicles are intended for suborbital research and tourism flights. The naming contest aims to engage the public in the company’s next phase of operations. Results will be announced after the voting period closes. The extension allows more time for enthusiasts to participate in shaping the identity of the upcoming fleet. SpaceX recovers Starship from Indian Ocean and begins return to Texas — Phys.org Space SpaceX completed recovery of the most recent Starship test article from the Indian Ocean roughly a month after its launch. The spacecraft is now being transported back to Starbase for inspection and analysis. Engineers will examine the vehicle’s heat shield and structure to assess performance during reentry and splashdown. This marks the largest salvage operation the company has conducted for a Starship prototype. Data from the recovered hardware will inform upgrades ahead of future test flights. The operation demonstrates the feasibility of retrieving large orbital vehicles after water landings. Post-flight analysis will focus on thermal protection system integrity and structural loads. NASA releases replay videos of Sentinel-6B launch — NASA Science The agency posted launch footage of Sentinel-6B, which lifted off aboard a SpaceX Falcon 9 from Vandenberg Space Force Base.

Sentinel-6B will monitor ocean height, temperature, and salinity to support climate and weather research. The videos allow the public to review the full ascent sequence and spacecraft separation. The mission extends the Jason series of ocean-observing satellites that have operated since 1992. Data from Sentinel-6B will feed into models used by weather forecasters and climate scientists worldwide. President Trump addresses Expedition 75 crew from Johnson Space Center — NASA Science President Trump spoke with the Expedition 75 astronauts after presenting the Congressional Space Medal of Honor to the Artemis II crew at the same location. The conversation covered ongoing station operations and future exploration goals. Expedition 75 continues science and maintenance activities aboard the International Space Station. The call occurred during the president’s visit to NASA’s Johnson Space Center in Houston, Texas. Crew members discussed daily research tasks and preparations for upcoming resupply missions. The exchange highlighted coordination between national leadership and orbital operations. Cosmic Spotlight The MIT CERBERUZ team’s waste-to-powder system turns everyday trash into manufacturing feedstock by grinding mixed materials to a uniform particle size. This approach could let crews on the Moon or Mars turn packaging and worn equipment into new tools or habitat components without waiting for resupply. The $775,000 award funds further testing to ensure the powder works reliably in additive manufacturing systems under lunar gravity and vacuum conditions. The team’s process handles fabrics, plastics, foam, and metals together, avoiding the need for separate sorting streams that would add complexity on long missions. What remains unclear is how radiation exposure over months or years will alter the recycled material’s strength and chemical stability once it leaves Earth’s protective environment. Cosmic Deep Dive: Turning Trash Into Tools Off Earth Imagine every kilogram of waste generated on a lunar base must either be stored forever or turned into something useful, because lifting replacement materials from Earth costs thousands of dollars per kilogram. The LunaRecycle challenge winner shows one path forward: grind mixed plastics, fabrics, and metals into a fine powder that can be fed into 3D printers to create new parts on demand. In practice, a single crew member might produce several kilograms of trash each week; over a year that adds up to hundreds of kilograms that could instead become brackets, insulation panels, or even simple tools. The surprising number is the $775,000 prize itself, which reflects how seriously NASA takes the logistics problem of sustaining crews far from resupply. The CERBERUZ approach avoids pre-sorting by treating all common spacecraft materials as a single feedstock stream. Yet the open question is whether repeated grinding and reforming will preserve the mechanical properties needed for structural parts, or whether radiation and thermal cycling will make the recycled material brittle in ways we cannot yet predict from ground tests alone. Space news continues to show steady progress on the practical challenges of living and working beyond Earth. ```claims []

Forecasters expect earlier and more precise severe-weather alerts as a direct result. The constellation’s staggered launches have already demonstrated incremental improvements in data latency. Next, teams will complete the orbit-raising sequence and begin on-orbit checkout of the advanced instruments. Cosmic Deep Dive: How Protoplanetary Disks Race Against Stellar Winds A typical protoplanetary disk stretches several times the distance from the Sun to Neptune, yet the gas it contains can vanish in as little as three million years under the push of a young star’s intense wind. Picture a city-sized reservoir of construction material being steadily blown away by a hurricane that never stops; that is the timescale on which planets must finish assembling. Inside the disk, dust grains collide and stick, gradually building rocky cores that then pull in surrounding gas if they reach roughly ten Earth masses before the supply disappears. The faster the central star spins and flares, the shorter that window becomes, which is why many observed systems end up with only small, rocky worlds instead of gas giants. We still do not know exactly why some disks lose their gas in under two million years while others linger for five or six, even around stars of similar mass and age. Space news kee
