On 31 January 1958, Explorer 1, America’s first satellite, began returning a baffling pattern from its Geiger counter: ordinary cosmic-ray counts followed by unexplained zeros. Van Allen’s team suspected the instrument was not failing but saturating under radiation too intense to register; two months later, Explorer 3’s complete recordings confirmed that the apparent silence marked a vast radiation belt surrounding Earth—the first of the belts now bearing Van Allen’s name.
11+ hour, 44+ min ago (515+ words) Explorer 1’s zero counts proved to be detector overload, and Explorer 3’s continuous record exposed the first of Earth’s Van Allen radiation belts....
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, 20+ 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, 23+ 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....
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
4+ day, 12+ 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, 16+ 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....
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, 16+ 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. By Deep Field · Edited by Lachlan Brown Published September 7, 2026 · How we edit The Milky Way’s…...
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, 16+ 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, 16+ 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. By Deep Field · Edited by Justin Brown Published September 7, 2026 · How we edit The open questions are…...
Despite being only about half Earth’s diameter, Mars has nearly as much total surface area as all of Earth’s continents combined—the difference is that oceans cover 71% of our planet, while modern Mars has no permanent bodies of liquid water.
1+ week, 8+ hour ago (980+ words) Mars has about 97% as much surface area as Earth’s dry land, a geometrical coincidence created by the oceans covering most of the larger planet....
Nearly every element in your body except hydrogen was forged by stars—the calcium in your bones and much of the iron in your blood came through ancient supernovae, while the hydrogen flowing through you was born before the first star existed.
1+ week, 1+ day ago (982+ words) Hydrogen predates the stars, while generations of stellar fusion, supernovae and galactic recycling supplied the heavier elements now arranged into living bodies....
