Scientists have discovered that there is ice deep inside planets like Neptune and Uranus and want to find out what form it takes and how it behaves. They cannot dig for it and transport it all the way back to Earth, so they do the next best thing: recreate those extreme conditions in the lab. https://phys.org/news/2026-09-scientists-strange-ice-interiors-neptune.html Planetary Sciences Fri, 11 Sep 2026 14:40:08 EDT news708352479 In early 2017 and 2023, California experienced two catastrophic and record-breaking floods that caused billions of dollars in damage, triggered mudslides and forced thousands of people to evacuate. Why this happened left scientists scratching their heads. Both disasters struck during La Niña conditions, which normally bring drier-than-normal weather to California. https://phys.org/news/2026-09-atmospheric-events-world-triggered-devastating.html Earth Sciences Thu, 10 Sep 2026 11:50:01 EDT news708256790 It is thought the sun may have engulfed a super-Earth-sized planet early in its history. Now, a new study has gone a step further, suggesting that such an event may have left behind detectable clues inside the sun that could still be visible today. https://phys.org/news/2026-09-fingerprints-sun-reveal-swallowed-planet.html Planetary Sciences Thu, 10 Sep 2026 09:20:02 EDT news708248158 Mercury's surface is riddled with wrinkles, evidence of a once-larger planet that has shrunk over time. A new study finds that Mercury may have contracted 10% to 30% more than previously thought—a loss of nearly 12 miles (19 kilometers) of total diameter since the planet formed—due to debris from impact craters obscuring signs of the planet's shrinking. https://phys.org/news/2026-09-mercury-thought.html Planetary Sciences Thu, 10 Sep 2026 09:00:05 EDT news707736901 An international team led by researchers from the University of São Paulo (USP) in Brazil has developed an innovative method to identify stars that have consumed the planets around them. The technique detects variations in the abundance of beryllium, a relatively rare chemical element, and could open a new window into studying the evolution of planetary systems. https://phys.org/news/2026-09-beryllium-stars-swallowed-rocky-planets.html Astronomy Wed, 09 Sep 2026 17:30:01 EDT news708191461 The Anthropocene became part of the zeitgeist after Nobel laureate Paul Crutzen launched the idea in 2000. This is the notion that a crescendo of human impacts has recently propelled Earth out of the relatively stable climatic conditions of the Holocene epoch, during which human civilization developed and flourished, to produce a new kind of planet. https://phys.org/news/2026-09-anthropocene-geological-epoch-idea-world.html Earth Sciences Wed, 09 Sep 2026 13:20:06 EDT news708170815 New research has revealed that ancient builders deliberately transported enormous 25-tonne stones across at least 18 kilometers (11 miles) to build Britain's tallest surviving prehistoric stone row—the iconic Devil's Arrows. https://phys.org/news/2026-09-prehistoric-builders-hauled-tonne-stones.html Archaeology Tue, 08 Sep 2026 19:10:01 EDT news708104941 We usually think of auroras as beautiful lights in the night sky. I see them as visible traces of a connection between the sun, Earth's magnetic field and the atmosphere. This led me to an origin-of-life question: Could the planetary structure that produces auroras also have organized chemical reactions on early Earth? https://phys.org/news/2026-09-early-earth-auroral-belts-natural.html Astrobiology Mon, 07 Sep 2026 20:40:04 EDT news707989182 Two Mercury-bound spacecraft left their mother ship behind on Thursday and headed down the home stretch of their nearly decade-long voyage to the solar system's smallest and closest-to-the-sun planet. https://phys.org/news/2026-09-pair-spacecraft-closer-mercury-decade.html Planetary Sciences Thu, 03 Sep 2026 12:30:02 EDT news707656831 Recent observations with NASA's Hubble Space Telescope have revealed a giant, evolving, 10-sided atmospheric wave encircling Saturn's south pole. This discovery marks the first time a large, regular-sided jet pattern has been observed in the planet's southern hemisphere. The feature appears remarkably similar to Saturn's famous hexagon at its north pole but is also distinctly different, suggesting scientists may be witnessing a new atmospheric phenomenon developing on the iconic gas giant. https://phys.org/news/2026-09-hubble-tracks-decagon-encircling-saturn.html Astronomy Wed, 02 Sep 2026 16:40:07 EDT news707580122 Astronomers at Lund University in Sweden have found evidence of exocomets—comets in other solar systems—orbiting a young star similar to our sun. The observations point to a possible mechanism for how water might be transported from the cold outer regions of the planetary system to regions where planets form. https://phys.org/news/2026-09-young-sunlike-reveals-comets-planets.html Astrobiology Wed, 02 Sep 2026 12:20:01 EDT news707564222 More than 3 billion miles (4.8 billion kilometers) from Earth, an ancient icy object is slowly awakening. As it drifts inward through the solar system, the frozen body known as Centaur 450P/LONEOS has begun releasing gas and dust—behavior more commonly associated with comets than with centaurs, the small icy objects that typically orbit between Jupiter and Neptune. https://phys.org/news/2026-09-saturn-encounter-distant-centaur-path.html Planetary Sciences Tue, 01 Sep 2026 18:00:04 EDT news707499541 When exploring solar system bodies for signs of past or present life, scientists have mainly focused on planets that have (or had) a liquid surface similar to Earth's. However, mounting evidence suggests that the ingredients for life may exist in a very different environment: the highly acidic clouds that blanket Venus. https://phys.org/news/2026-08-peptides-harsh-venus-conditions.html Astrobiology Mon, 31 Aug 2026 15:00:10 EDT news707388361 The evolutionary histories of Earth and Mercury differ fundamentally. The smallest planet, closest to the sun, likely began cooling early on, much like a setting pudding: As early as about 1 billion years after its formation, Mercury's volcanic activity came to a halt, and a solid, continuous "rock skin" formed on the planet's surface. Earth's crust, on the other hand, is still in motion: Volcanism and plate tectonics are constantly stirring up the "Earth pudding." Exactly what Mercury's unique volcanic past looked like and how it shaped its current appearance remain unclear. However, researchers can gain important clues from the composition of its surface. https://phys.org/news/2026-08-mercury-crust-deeper-hotter-volcanic.html Planetary Sciences Fri, 28 Aug 2026 12:40:01 EDT news707135642 When engineers look to nature for inspiration, they often turn to living systems. The flight of birds has influenced aircraft design, gecko feet inspired new adhesives and lotus leaves led to the development of self-cleaning surfaces. https://phys.org/news/2026-08-geomimicry-framework-sustainable-materials.html General Physics Thu, 27 Aug 2026 08:27:53 EDT news707038047 Stanford researchers have offered an explanation for why some sizzling, lava-covered worlds nestled tightly around their stars can retain their atmospheres. At such close quarters, intense stellar radiation should strip away a planet's air. https://phys.org/news/2026-08-lava-exoplanets-retain-atmospheres-billions.html Astrobiology Wed, 26 Aug 2026 11:40:04 EDT news706957007 Planets form from disks of gas and dust around young stars, but the gas needed for growth does not last forever. New observations from NASA's James Webb Space Telescope (JWST) now offer a new view of how this gas escapes and how the process changes as young planetary systems develop. https://phys.org/news/2026-08-jwst-reveals-planets.html Astronomy Tue, 25 Aug 2026 17:50:01 EDT news706897742 Around 4.6 billion years ago, the solar system was little more than a giant ball of gas and dust. Over the next few million years, this "solar nebula" underwent a huge transformation, flattening into a disk of matter that then condensed to form the central sun and orbiting planets. https://phys.org/news/2026-08-meteorite-magnetism-sun.html Planetary Sciences Mon, 24 Aug 2026 19:10:01 EDT news706810983 Seismic waves produced by thunderstorms, called thunderquakes, can be used as a novel source for seismic imaging, according to a new study led by researchers at Penn State. https://phys.org/news/2026-08-thunderquakes-enable-seismic-imaging-earth.html Earth Sciences Fri, 21 Aug 2026 14:00:01 EDT news706362481 During a coronal mass ejection (CME), the sun hurls billions of tons of magnetized plasma into space. These eruptions are among the most powerful events in the solar system, and when they are aimed toward Earth, they can seriously threaten the satellites and power grids we depend on. For now, it remains notoriously difficult to predict how these eruptions evolve over time—and, in turn, whether they might be heading toward us. https://phys.org/news/2026-08-interplanetary-spacecraft-capture-coronal-mass.html Space Exploration Fri, 21 Aug 2026 08:50:42 EDT news706521006 A new study from Monash University has delivered the most complete and accurate digital map of Earth's windblown sand dunes to date. The research, published in Nature Communications, answers long-standing questions about why dunes form where they do, unlocking key insights into climate conditions on Earth and other planets. https://phys.org/news/2026-08-global-sand-dunes-reveals-clues.html Planetary Sciences Thu, 20 Aug 2026 10:20:03 EDT news706436221 A current system in the Atlantic Ocean that shapes regional climates and distributes ocean nutrients also serves as a control knob to help regulate temperatures across the planet, new research has found. https://phys.org/news/2026-08-weakening-atlantic-ocean-current-earth.html Earth Sciences Mon, 17 Aug 2026 18:10:01 EDT news706206001 It's nearly 170 million years old. It's more than 2.5 times the size of Earth. And it's the first exoplanet discovered and cataloged by researchers with the Wisconsin Center for Origins Research (WiCOR). https://phys.org/news/2026-08-mega-earth-gj-523b-massive.html Astronomy Mon, 17 Aug 2026 12:40:04 EDT news706181881 Researchers have helped unravel the mystery of why certain pairs of stars pulse with regular, long-period bursts of radio waves. The particular class of objects observed comes in pairs that always include a compact dead star, called a white dwarf, locked in orbit with an M dwarf, a red star smaller than our sun. https://phys.org/news/2026-08-synchronized-star-pairs-unleash-radio.html Astronomy Thu, 13 Aug 2026 18:00:04 EDT news705846361 The building blocks of rocky planets may have begun forming just 100 million years after the Big Bang—long before the first galaxies even existed—according to new research from the University of Portsmouth. https://phys.org/news/2026-08-supernovae-seeded-rocky-planet-blocks.html Planetary Sciences Wed, 12 Aug 2026 17:20:03 EDT news705757021 Hundreds of Venus-like planets could soon help determine why some worlds become sweltering greenhouse hellscapes while others remain capable of supporting life. But before answering that question, scientists first need to know how fast those planets are spinning. https://phys.org/news/2026-08-planets-hellish.html Astronomy Mon, 10 Aug 2026 10:00:01 EDT news705573181 Boston College scientists have determined that a newly discovered meteorite from Mars is 1.27 billion years old and derived from a previously unsampled, pristine source on the Red Planet. The study is published in the journal Geochimica et Cosmochimica Acta. https://phys.org/news/2026-08-rare-mars-meteorite-billion-year.html Planetary Sciences Sun, 09 Aug 2026 10:20:01 EDT news705310410 Within our solar system, Uranus is a geometric oddball. Its spin axis tilts more than 90° from its orbit, so it essentially rolls on its side through space. In contrast, Earth and other planets tilt only moderately or not at all. What's more, the ice giant's magnetic field is strangely offset and tilted another 60°. https://phys.org/news/2026-08-uranus-unusual-rotation-day.html Planetary Sciences Fri, 07 Aug 2026 12:20:05 EDT news705316681 The Sloan Digital Sky Survey V (SDSS-V) has announced its 20th public data release (DR20), delivering a dramatic expansion of the Milky Way Mapper (MWM) scientific survey—the most detailed spectroscopic map yet assembled of stars in and around our home galaxy. https://phys.org/news/2026-08-galaxy-milky-mapper-survey-latest.html Astronomy Thu, 06 Aug 2026 18:30:01 EDT news705257521 A team of astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) has captured a massive stream of gas—one trillion miles, or 0.2 light-years, long—feeding the young triple-star system GW Orionis. These new observations provide the clearest evidence yet for how such "streamers" can tilt and twist the disks where planets are born. The findings are published in The Astronomical Journal. https://phys.org/news/2026-08-trillion-mile-gas-streamer-tilt.html Astronomy Thu, 06 Aug 2026 17:00:07 EDT news705248521
