Known physics suggests the early universe should have produced matter and antimatter in equal amounts. Nearly all of it annihilated into radiation, but roughly one extra matter particle survived for every billion pairs—and why that tiny imbalance existed remains one of physics’ deepest unsolved problems.
3+ hour, 12+ min ago (906+ words) The measured net baryon-to-photon ratio is about 6.1 parts in ten billion. Physics can describe the required ingredients for that excess, but no confirmed mechanism made it....
Opportunity’s solar panels were mysteriously getting cleaner long before the rover ever saw the suspected culprit: it did not photograph its first Martian dust devil until six and a half years after landing.
2+ day, 6+ hour ago (1267+ words) Opportunity’s changing power output recorded repeated wind-cleaning events years before its camera caught a dust devil. The six-and-a-half-year gap reveals the difference between detecting an effect and identifying its cause. By Mission Notes · Edited by Lachlan Brown Published September 10, 2026 · How…...
Olympus Mons grew so massive that parts of its lower flanks catastrophically collapsed, sending broken rock sliding hundreds of kilometres across the Martian plains—possibly lubricated when hot lava melted buried ice.
3+ day, 9+ hour ago (718+ words) Orbital evidence links Olympus Mons's aureole to immense flank failures. Water or ice may explain the long runout, but lava-driven melting remains one proposed mechanism....
Physicist Bhupal Dev at Washington University used the debris from GW170817 — the 2017 neutron star merger — to squeeze new limits on axion-like particles, treating the hot post-collision remnant as a natural forge for dark-matter candidates
3+ day, 16+ hour ago (302+ words) Physicist Bhupal Dev and colleagues have used the multi-year record of GW170817 — the 2017 neutron star merger seen in both gravitational waves and light — to tighten bounds on axion-like particles, treating the hot post-collision remnant as a natural forge for dark matter…...
About 70 young stars sit inside one dark knot of gas in the Carina Nebula: ESA's Webb Picture of the Month for August 2026 shows the Treasure Chest globule, 7,500 light years off, lit by a 19-solar-mass O-type star
3+ day, 21+ hour ago (362+ words) A stellar nursery the size of a city block holds a monster star waiting to reshape everything around it. By Deep Field · Edited by Justin Brown Published September 9, 2026 · How we edit The nickname belongs to the cloud, not the star....
In 2008, a team hauled 1,478 lunar data tapes and four obsolete drives to NASA Ames to recover pictures from the 1960s — and the laboratory where they restored those original views of the Moon in greater detail was an abandoned McDonald’s restaurant.
4+ day, 1+ hour ago (309+ words) The Lunar Orbiter Image Recovery Project restored old tape drives inside a former McDonald’s to retrieve detail preserved in recordings from the 1960s....
For years, mysterious little red dots kept appearing in James Webb images of the early universe — astronomers now think one is a “black hole star,” a growing black hole hidden inside a star-like gas cocoon the size of the solar system
4+ day, 17+ hour ago (17+ words) A telescope worth ten billion dollars stared into the dawn of time and came back with freckles....
Astronomers long expected the Milky Way and Andromeda to collide in about 4.5 billion years — but a 2025 study in Nature Astronomy, using Hubble and Gaia data, estimated only a roughly 50–50 chance of the galaxies merging within the next 10 billion years.
6+ day, 1+ hour ago (810+ words) The 2025 estimate depended on uncertain motions and neighbouring galaxies. A 2026 follow-up put the merger probability higher, showing why the forecast remains sensitive to the measurements.

ESO’s new MOONS spectrograph on the Very Large Telescope took first light able to watch about 1,000 cosmic targets at once through roughly 1,000 fibers, built to map millions of objects over its working life
6+ day, 2+ hour ago (30+ words) For the first time, astronomers can map the cosmos in bulk, capturing the light signatures of a thousand distant objects at once to unlock the history of billions of galaxies....
Astronomers using Hubble found a new roughly 104,000-mile-wide ten-sided storm forming at Saturn’s south pole, a geometric twin to the famous hexagon that has long circled the north
6+ day, 2+ hour ago (168+ words) Saturn's symmetry breaks: a ten-sided storm now mirrors the planet's legendary hexagon, suggesting these geometric puzzles obey deeper physics we're only beginning to understand.
