    Fascinating Frontiers 🚀 Fascinating Frontiers - Space & Astronomy News Gravitational waves from tight white-dwarf pairs could soon reveal an entire population of exoplanets throughout the Milky Way. Top 12 Space & Astronomy Stories Earliest known compact quasar pair poses a black hole growth puzzle — Phys.org Space The oldest pair of compact quasars ever observed formed only 900 million years after the Big Bang. No current theoretical model explains how two actively feeding black holes reached such high masses so early. The pair carries the Hawaiian name Nāpōwawāʻenakaulua. Researchers discovered the system through observations that captured both objects in a single compact configuration. The finding highlights a gap in understanding of how supermassive black holes assembled in the first billion years of cosmic time. Further observations of the pair could test whether mergers or rapid accretion drove their early growth. Source: phys.org How ripples in space-time can reveal new exoplanets — Phys.org Space Two new studies detail how the LISA observatory will detect gravitational waves from double white dwarf binaries and identify planets orbiting within those systems. A planet’s gravitational tug imprints a Doppler modulation on the binary’s gravitational-wave signal, appearing as sidebands at higher and lower frequencies. The method works best for planets with masses and orbital periods that produce detectable sidebands. NASA’s James Webb Space Telescope could confirm candidates by detecting excess infrared light from the planet out to at least 500 light-years. The Milky Way contains an estimated 10 million double white dwarf systems with orbital periods under one hour, of which LISA is expected to resolve about 10,000. The first paper examines detection thresholds while the second explores confirmation strategies with infrared observations. The concept was first proposed in 2008 by Japanese astronomer Naoki Seto. Casey McGrath, a postdoctoral researcher at the University of Maryland, Baltimore County and NASA’s Goddard Space Flight Center, led the detection-method paper and noted that an exoplanet’s presence becomes imprinted on the gravitational wave signal. Scott Noble, a theoretical astrophysicist at NASA Goddard, explained that the modulation adds sidebands similar to how radio carrier frequencies carry messages. Mary Anne Limbach, an assistant research scientist at the University of Michigan, emphasized that joint detections with Webb will establish that gravitational signals correspond to genuine planets. White dwarfs are the Earth-sized remnants of stars like the Sun, and no planets have yet been found around a binary white dwarf. LISA, led by ESA with NASA contributions including telescopes and hardware, is slated for launch in the mid-2030s.

Source: reddit.com Cosmic Deep Dive: How Dwarf Galaxies Distribute Heavy Elements Across the Cosmos Dwarf galaxies are the universe’s most common residents, yet each one is only about one-tenth the width of the Milky Way. If the Milky Way stretches 100,000 light-years across and holds hundreds of billions of stars, a typical dwarf galaxy spans roughly 10,000 light-years and contains just a few billion stars. NGC 4449 offers a clear example captured by the Hubble Space Telescope. The galaxy continues forming stars at a brisk rate, yet its gas contains far less oxygen than chemical-evolution models predict. The shortfall points to powerful outflows driven by the galaxy’s own stellar winds and supernovae. These winds act like galactic bellows, sweeping oxygen and other heavy elements out of the shallow gravitational well of the dwarf and into intergalactic space. Because dwarfs vastly outnumber larger galaxies, their collective outflows may supply a surprising fraction of the heavy elements now found between galaxies. The same process helps seed future generations of stars and planets with the raw materials needed for rocky worlds and life. Observations of NGC 4449 and similar systems reveal that the efficiency of this removal exceeds what current simulations assume. The galaxy’s stellar winds and supernovae appear surprisingly effective at blowing away oxygen and other heavy elements. This efficiency suggests that tiny galaxies play a big role in spreading the building blocks of stars, planets, and life throughout the universe. The image shows NGC 4449 as a irregular dwarf with active star-forming regions scattered across its disk. Hubble data indicate that the galaxy is missing more oxygen than models predict for its mass and star-formation history. The outflows carry material beyond the galaxy’s reach, enriching the surrounding intergalactic medium. Over cosmic time, this enrichment influences the chemical composition of gas that will later collapse into new galaxies. The open question is whether every dwarf galaxy behaves this way or whether some retain more of their newl

Gravity from an unseen neighbor makes the two planets wobble like tops, swinging each out of alignment with our line of sight. The planet should next transit sometime between 2056 and 2076. Researchers observed the system with TESS between 2019 and 2026 and noted transit times shifting by up to six hours.

Source: science.nasa.gov Cosmic Deep Dive: How Mid-Infrared Light Reveals the True Shape of a Comet Nucleus A comet nucleus only a few kilometers across can swing through the inner solar system at tens of kilometers per second, yet from Earth it often appears as nothing more than a fuzzy point of light. Mid-infrared observations change that picture by capturing the faint heat the nucleus itself radiates. When the Subaru Telescope turned its mid-infrared instruments on Comet 2P/Encke, the data showed the nucleus is not a sphere but an elongated body roughly 7 kilometers long and 3 kilometers wide. That shape is comparable to a small city stretched into a rough oval, rotating once every few hours and exposing different faces to the Sun. The measurement works because mid-infrared wavelengths sense temperature directly. As the nucleus spins, its surface warms and cools, and the changing brightness at these wavelengths traces the projected area and thermal properties. By modeling how the emission varied over a full rotation, researchers extracted both the long and short axes and determined that the surface reached 328 ± 7 Kelvin at the time of observation. That temperature is hot enough to drive the comet’s activity yet still consistent with a dark, low-albedo surface that absorbs sunlight efficiently. The same technique also distinguishes the nucleus from the surrounding coma of dust and gas. Visible light is scattered by the coma and can mask the true size of the solid body, but mid-infrared light comes mostly from the warmer nucleus itself. This separation lets astronomers measure the nucleus even when the comet is active and bright in optical wavelengths. What remains unknown is how representative Encke’s elongated shape is of other short-period comets. Repeated close passages to the Sun could grind nuclei into more spherical forms or fracture them into irregular shapes, yet only a handful of nuclei have been measured at this level of detail. Future mid-infrared observations of additional comets will show whether most nuclei share this stretched geometry or whether Encke is an outlier shaped by its particular dynamical history. Two new missions and one vanishing world kept the week lively.

    Ep 248: Dwarf galaxies hold onto only 15 percent of the oxygen their stars create.

    Fascinating Frontiers 🚀 Fascinating Frontiers - Space & Astronomy News Dwarf galaxies hold onto only 15 percent of the oxygen their stars create. Top 12 Space & Astronomy Stories Nearby Dwarf Galaxies Retain Just 15 Percent of Produced Oxygen — Universe Today Researchers using Hubble studied 37 nearby dwarf galaxies and measured both retained and lost oxygen across their lifetimes. Only about 15 percent of the oxygen produced by stars remains inside these galaxies today, mostly in gas with smaller fractions in stars and dust. The rest has been driven out by radiation from massive stars and core-collapse supernovae into the circumgalactic medium and beyond. In these low-mass systems the oxygen-to-hydrogen ratio reaches one atom per 10,000 to 20,000 hydrogen atoms, compared with one per 2,000 in the Milky Way. The GLOW project combines new and archival data from Hubble, Spitzer, the Very Large Array, and the Australian Telescope Compact Array to track how gas and heavy elements move between galaxies, their halos, and the intergalactic medium. The results show low-mass galaxies lose oxygen more readily than current simulations predict because of weaker gravity. Most of the oxygen comes from core-collapse supernovae, the explosive deaths of massive stars, though a very small fraction is also produced in other types of supernovae caused by the remnants of low-mass stars becoming unstable or merging. Grace Telford, the paper’s second author and an assistant professor at the University of Utah’s Dept. of Physics & Astronomy, noted that energetic radiation from massive stars and their deaths as supernovae drive oxygen-rich gas out of the galaxies over time. The missing oxygen is likely in the gaseous halos surrounding the galaxies, that is, the Circumgalactic Medium, and has also likely traveled even farther into the intergalactic medium. The GLOW project is jointly funded by NASA and the National Science Foundation and is a large-scale effort to understand how gas and heavy elements move between low-mass galaxies, their CGM, and the intergalactic medium. Similar measurements of oxygen lost from galaxies have been made for massive galaxies like the Milky Way, but low-mass galaxies are expected to lose oxygen more easily due to their smaller gravity, and the paper demonstrates that this is indeed the case.

The work focuses on gases that life would alter or produce, allowing researchers to flag worlds whose atmospheres look too inert to support biology. One open question is how varying stellar types would change the baseline lifeless atmosphere and whether some false positives could still mimic biological signals. Source: space.com Cosmic Deep Dive: How Galactic Winds Remove Heavy Elements from Dwarf Galaxies Picture a dwarf galaxy no larger than a few thousand light-years across yet still forming stars at a steady clip. Its total mass sits so low that the energy from a handful of supernovae can literally blow material clear out of the system. Compare that scale to the distance across the continental United States, roughly three thousand miles from coast to coast; a dwarf galaxy is thousands of times larger in linear extent, yet its gravitational grip remains fragile enough that a few energetic events can unbind its gas. In our own Milky Way the ratio of oxygen to hydrogen atoms hovers near one oxygen atom for every two thousand hydrogen atoms. In the dwarf galaxies studied by the GLOW team that ratio drops to one oxygen atom for every ten thousand to twenty thousand hydrogen atoms. The difference arises because the smaller gravitational pull cannot hold onto the hot, metal-rich gas blasted outward by radiation pressure and supernova shocks. Once the gas leaves the galaxy it joins the circumgalactic medium and, in many cases, travels even farther into the space between galaxies. The same process operates in larger systems, but the shallower potential wells of dwarfs make escape far easier and more complete. Hubble spectra combined with infrared and radio observations let researchers tally both the oxygen still locked inside stars and gas and the oxygen that has already departed. The measurements show that only about fifteen percent of all oxygen ever created by stars remains inside these galaxies today. It combines a large set of new and archival observations of low-mass galaxies from both ground-based and space telescopes. Current computer simulations of galaxy formation under-predict this level of loss, which means the models still miss some detail of how massive stars couple their energy to the surrounding gas. The unanswered question is exactly which feedback channels—radiation, cosmic rays, or clustered supernovae—drive the most efficient ejection, and whether that efficiency changes with the galaxy’s star-formation history. We can measure the oxygen that remains and the oxygen that has left, but the precise balance of forces that decides how much gas escapes in any given dwarf galaxy remains an open puzzle. Space keeps delivering fresh measurements that tighten our picture of how galaxies and planets form.

Type Ia events occur when a white dwarf reaches the Chandrasekhar limit and detonates, providing astronomers with a standard candle whose peak brightness is consistent enough to measure cosmic distances. The same process also seeds the universe with iron-peak elements, including much of the iron now found in human blood. The galaxy NGC 1433 features a double-ring central structure formed by tightly wound spiral arms along its bar. ATLAS uses four 0.5-meter telescopes to image the entire sky multiple times each night. Once confirmed as a Type Ia event, the supernova's light curve can refine the distance to NGC 1433 without relying solely on other indicators. The explosion leaves no compact remnant because the runaway fusion consumes the entire star. Source: reddit.com Cosmic Deep Dive: How Big Bang Nucleosynthesis Tests Cosmological Models The first few minutes after the Big Bang set the chemical recipe for the entire universe, locking in ratios of hydrogen, helium, and trace lithium that astronomers can still measure today. In that brief window the temperature and density allowed protons and neutrons to fuse into light nuclei before expansion cooled everything too much for further reactions. A model that gets these ratios wrong cannot claim to describe the early universe correctly, no matter how well it fits later observations. The CCC+TL cosmology proposes a universe 26.7 billion years old without invoking dark matter or dark energy, yet it must still reproduce the same primordial abundances that standard cosmology matches. Imagine watching the universe's first three minutes unfold at a rate where every second corresponds to a million years of later cosmic time. Within that compressed interval the neutron-to-proton ratio freezes, deuterium forms, and almost all helium is created. The resulting mix leaves roughly 25 percent helium by mass and trace amounts of lithium-7, numbers that depend sensitively on the expansion rate and baryon density at that epoch. Any alternative model changes either the expansion history or the particle content and therefore predicts different yields. When researchers plug the CCC+TL parameters into nucleosynthesis calculations, the predicted helium and deuterium fractions line up with values measured in the oldest stars and in distant gas clouds whose light has traveled for billions of years. The University of Ottawa team compared these predictions directly against spectroscopic data and found consistency across multiple light-element channels. That agreement is surprising because the model alters the overall age and energy budget of the cosmos yet still satisfies a constraint fixed when the universe was only seconds old. The test does not prove the model correct, but it shows the framework survives one of the most precise early-universe benchmarks available. What remains unsettled is whether the same parameters can simultaneously satisfy later observations such as the cosmic microwave background power spectrum and the growth of large-scale structure. Those datasets probe epochs hundreds of thousands of years after nucleosynthesis and could reveal tensions not yet visible in the light-element data. If future measurements tighten the allowed range for the baryon density or the expansion rate, the CCC+TL model may need adjustment or may be ruled out. We already know the universe produced helium and deuterium in specific proportions; the open question is which complete descri

Source: phys.org Cosmic Deep Dive: How Tidal Heating Sustains Lunar Volcanism Imagine a rocky body the size of a large city whose interior remained warm enough to generate lava flows two billion years after standard cooling models predicted it should have frozen solid. That body is Earth's Moon. Samples returned by China's Chang’e-5 mission formed only about two billion years ago yet display clear volcanic textures. Conventional thermal evolution calculations expected the Moon to have lost its internal heat long before that time, leaving its mantle cold and solid. The resolution lies in repeated gravitational stretching and squeezing by Earth. As the Moon travels around our planet, Earth's gravity raises tides in the lunar rock that repeat on a monthly cycle. Friction generated inside the rock converts mechanical energy into heat, similar to the warmth produced when a paperclip is bent back and forth many times. Over billions of years this steady input can maintain pockets of the lunar mantle above the melting point even while the rest of the body cools. Tidal heating reaches its peak when the Moon orbits closer to Earth. Early in lunar history the Moon circled at roughly one-third its present distance, so the gravitational forces were far stronger. That extra energy likely sustained widespread melting for hundreds of millions of years. As the Moon receded through tidal interactions, the heating rate declined but never vanished completely. The Chang’e-5 basalts indicate that at least some regions stayed warm enough for volcanism until relatively recently in lunar history. Miao Chen of the Chengdu University of Technology and colleagues published the tidal-heating explanation in the journal Planet. Their work shows how the cumulative effect of monthly flexing can offset the expected cooling. The process operates most efficiently in regions where rock properties allow greater dissipation of tidal energy into heat. We still do not know exactly how that heat was distributed through the Moon's interior. Current models disagree on whether tidal energy concentrated in a thin layer near the core-mantle boundary or spread more evenly through the mantle. Resolving the distribution requires new measurements of the Moon's present-day internal temperature profile and the precise rate at which heat continues to escape from the surface today. Without those data, scientists cannot determine whether tidal heating alone accounts for the observed volcanic activity or whether additional mech

Source: dailytrojan.com Cosmic Deep Dive: How Globular Clusters Record the Milky Way’s Early Assembly A single globular cluster can hold more stars than the entire population of a mid-sized city yet fit inside a volume smaller than the distance from Earth to the nearest star beyond the Sun. M30 packs tens of thousands to millions of stars into a sphere whose outer edges lie only tens of light-years across, a density that would make night skies on any hypothetical planet inside it blaze with thousands of suns at once. These clusters formed when the universe itself was young, between 11.5 and 13.5 billion years ago, and their stars still carry the chemical fingerprints of that era because they have evolved in near isolation ever since. Imagine riding alongside a photon leaving one of M30’s ancient stars: after traveling 27,500 light-years you would cross the halo of the Milky Way and finally reach Earth, carrying information about elements forged before our own Sun existed. Hubble’s repeated observations of M30 combined data from the Advanced Camera for Surveys and Wide Field Camera 3 across programs spanning more than fifteen years, revealing stars down to just 20 percent of the Sun’s mass and tracking the motions of different stellar populations within the cluster. The same images that show blue straggler stars also map how the cluster’s overall structure has changed, because the telescope’s long baseline lets astronomers measure tiny shifts in star positions over time. Earlier programs surveyed dozens of Milky Way globular clusters in red and near-infrared light while a later program returned to M30 using three filters that captured bluer light. Those bluer observations proved critical for studying exotic objects and the multiple populations of stars that can inhabit a single globular cluster. The most recent observations tracked how different populations moved over the fifteen years since Hubble first imaged them. Yet M30 and dozens of other clusters orbit the Milky Way in the opposite direction from the galaxy’s spin, a fact that raises a direct question: were these clusters born inside the Milky Way or were they stolen from smaller galaxies the Milky Way swallowed long ago? The chemical patterns and orbital directions alone cannot yet distinguish between those two histories. Resolving the difference would require either precise measurements of the clusters’ internal velocities at scales Hubbl

Top 12 Space & Astronomy Stories ExoMars spots hydrogen chloride over Martian fissures — European Space Agency The ExoMars Trace Gas Orbiter detected hydrogen chloride above volcanic fissures in the Alba Mons region. The gas appeared in early northern summer, outside the usual seasonal pattern tied to dust and water cycles. Fresh narrow fissures hundreds of meters long showed color changes consistent with deposits from escaping gases. Researchers link the release to hot magma beneath the surface.

Source: space.com Cosmic Deep Dive: How vibrations reveal what lies beneath planetary surfaces Picture a rover on Mars that must decide in minutes whether a boulder blocking its path is a loose rock the size of a suitcase or a buried slab the size of a truck. The difference determines whether the machine wastes hours chipping at immovable stone or simply drives around it. On Earth we make that judgment by eye and a quick kick; on another world the rover has no such intuition. Virginia Tech engineers are teaching machines to listen instead. Their method starts with a simple tap. An instrumented hammer strikes the visible part of a rock while a scanning laser Doppler vibrometer records the vibrations that travel through the buried portion and back out. Eighteen concrete blocks of different sizes and burial depths were planted in sand to create a training set. The team measured vibrations at multiple points on each exposed surface, then fed the frequency patterns and visible geometry into a compact neural network with only two hidden layers. Once trained, the model could estimate burial depth from new vibration readings. The approach works because vibrations travel differently through loose sand than through solid rock; a buried boulder returns a distinct signature compared with a surface pebble. On Mars or the Moon the same principle could let a robotic excavator know when further effort is pointless. Erik Komendera, who once worked as an engineer at NASA Langley Research Center, led the project with Ph.D. candidate Yiyan Ruan. Their results appear in the IEEE Sensors Journal under DOI 10.1109/jsen.2026.3733381. The researchers note that estimating burial depth remains tricky because feedback is affected by rock geometry and the way soil holds the object. By carefully selecting features from vibration measurements and exposed geometry they produced reliable data with a small neural network. Those models could one day guide a robotic excavator on Mars to handle obstacles correctly in the terrain. For now the team plans to continue bui
