What, exactly, is a plant made of? Scientists have a good understanding of the essential nutrients plants need to grow. But what plants need and what they contain are not necessarily the same. https://phys.org/news/2026-10-global-database-fuller-picture-elements.html Biochemistry Thu, 22 Oct 2026 18:20:11 EDT news711903362 The NASA/ESA/CSA James Webb Space Telescope continues to reveal hidden parts of the cosmos with its advanced suite of infrared instruments. In a newly released image, Webb revealed many stars previously hidden by the dust clouds of NGC 7129, a stellar nursery about 3,300 light-years from Earth in the constellation Cepheus. The image is already improving our understanding of how new stars are born and evolve with time. https://phys.org/news/2026-10-webb-captures-stars-early-stages.html Astronomy Thu, 22 Oct 2026 13:40:18 EDT news711878476 In this Picture of the Month from the NASA/ESA James Webb Space Telescope, we visit a turbulent cauldron of star formation to see what is brewing inside dense clumps of gas. This is a star-forming region named LHA 120-N 159, or simply N159, located 161,000 light-years away in the Large Magellanic Cloud (LMC), one of the satellite galaxies orbiting the Milky Way galaxy. This image spans about 230 light-years across. https://phys.org/news/2026-10-webb-image-reveals-young-stars.html Astronomy Thu, 22 Oct 2026 13:40:01 EDT news711892283 Technion researchers have presented evidence for the existence of solar-storm-like outbursts near supermassive black holes, which can be a million times larger than the sun or more. The phenomenon was discovered in the vicinity of the black hole in the galaxy NGC 3783, and the researchers' findings were published in The Astrophysical Journal Letters. https://phys.org/news/2026-10-black-hole-uncover-evidence-solar.html Astronomy Thu, 22 Oct 2026 11:03:31 EDT news711885705 Scientific estimates show that there should be between about 100 million and 1 billion stellar-mass black holes in the Milky Way. But they aren't easy to locate. They're not like supermassive black holes (SMBH) at the centers of galaxies. Those are usually easy to spot for different reasons. https://phys.org/news/2026-10-black-holes-neighborhood.html Astronomy Thu, 22 Oct 2026 10:40:07 EDT news711871458 A new study suggests that some of the heaviest rocky planets ever reported may not be as heavy as they look. These so-called 'mega-Earths,' rocky planets weighing more than about 10 Earths, could be an illusion created by activity on their host stars. The paper was posted to the arXiv preprint server on Oct. 8. https://phys.org/news/2026-10-mega-earths-real-stellar-oversized.html Planetary Sciences Thu, 22 Oct 2026 09:50:01 EDT news711879490 A team of researchers at NASA's Goddard Space Flight Center (GSFC) has developed a new instrument designed to eliminate blind spots between lines of lidar data on Earth's surface. Built with support from NASA's Earth Science Technology Office (ESTO), the Concurrent Artificially-intelligent Spectrometry Lidar System (CASALS) could help researchers map the features of Earth's surface in detail. Rather than mechanically steering a laser with moving mirrors, CASALS steers light using wavelength itself, generating a continuous, 3D swath of the ground below. https://phys.org/news/2026-10-nasa-casals-instrument-bridges-gaps.html Planetary Sciences Wed, 21 Oct 2026 14:20:09 EDT news711795891 An international team of researchers, including members from the University of Michigan, has revealed surprising results that could rewrite our understanding of a key transition in the early universe. https://phys.org/news/2026-10-hubble-supernova-role-cosmic-reionization.html Astronomy Wed, 21 Oct 2026 13:20:15 EDT news711800461 Earthquakes and the seismic waves they generate provide some of the best clues to Earth's interior. To extend that success to other worlds, scientists placed seismometers on the Apollo missions to the moon and on the Viking Mars landers, which reached Mars in 1976. Though the Apollo detectors proved a resounding success, Viking's results on Mars were less clear: Viking 1's seismometer failed to deploy properly, and Viking 2 recorded only two ambiguous events. https://phys.org/news/2026-10-reexamined-viking-reveals-marsquake-region.html Planetary Sciences Wed, 21 Oct 2026 12:40:06 EDT news711799802 A new study led by researchers at the Konkoly Observatory of the HUN-REN Research Centre for Astronomy and Earth Sciences (HUN-REN CSFK) in Budapest has revealed what makes a distant red giant star the most explosively active in the entire Kepler field—and the answer lies in a surprisingly subtle interplay between a close stellar companion, vast dark starspots and a highly efficient internal magnetic dynamo. https://phys.org/news/2026-10-astronomers-uncover-powerful-stellar-flares.html Astronomy Wed, 21 Oct 2026 09:20:06 EDT news711791342 Researchers at the U.S. Department of Energy's (DOE) Argonne National Laboratory have completed two of the largest cosmological simulations ever performed.

It's easier to send probes to the icy moons of Saturn or Jupiter, or even to Pluto, than to land on our innermost planet, Mercury. https://phys.org/news/2026-10-enigmatic-mercury-puzzle-lander.html Planetary Sciences Mon, 19 Oct 2026 09:20:02 EDT news711610218 Groundwater in many areas of the U.S. and across the globe is being depleted as pumping for drinking water and agriculture outpaces nature's ability to refill aquifers. In the most severe cases, this could lead to a point of no return, where an aquifer's physical structure collapses and it cannot be refilled. https://phys.org/news/2026-10-advance-aquifer-remote-statistical-groundwater.html Earth Sciences Mon, 19 Oct 2026 07:00:02 EDT news711603436 Japanese scientists are readying a mission to Mars' moons to retrieve samples that could help unlock the origins of the solar system and life on Earth, in what aims to be the first round trip to the Martian region. https://phys.org/news/2026-10-japan-historic-mission-mars-moon.html Space Exploration Sun, 18 Oct 2026 16:20:01 EDT news711555681 Japan is set to launch a spacecraft on the world's first mission to bring back samples from Phobos, one of the two small, potato-shaped moons orbiting Mars. https://phys.org/news/2026-10-japan-spacecraft-mission-samples-martian.html Planetary Sciences Sun, 18 Oct 2026 07:38:40 EDT news711527854 Lawrence Livermore National Laboratory (LLNL) researchers are developing three-dimensional simulations to examine how a nuclear device could be used to deflect or potentially disrupt an asteroid threatening Earth. https://phys.org/news/2026-10-simulations-explore-nuclear-mitigation-asteroid.html Planetary Sciences Sat, 17 Oct 2026 15:00:05 EDT news711191693 The ocean beneath Saturn's moon Enceladus lies under kilometers of ice, but some of its contents do reach the surface.

Hubble captured the image as part of a survey looking at 260 satellite galaxies around 22 Milky Way–like host galaxies within a radius of about 32 million light-years from Earth. Hubble has already observed 111 of these satellite galaxies. The remaining galaxies will take an additional 149 Hubble orbits, one orbit for each galaxy, to observe. https://phys.org/news/2026-10-nasa-hubble-spies-spiral-edge.html Astronomy Fri, 16 Oct 2026 13:40:08 EDT news711366863 A phenomenon rarer than a solar eclipse and more powerful than any single storm system is unfolding this fall, and NASA is tracking it closely. https://phys.org/news/2026-10-nasa-satellites-historic-el-nio.html Earth Sciences Fri, 16 Oct 2026 12:44:08 EDT news711373385 On May 10, 2025, a spacecraft built in the Soviet Union to land on Venus came home. Launched in 1972, Cosmos-482 was stranded by a failed upper stage of its rocket and circled Earth for 53 years. In its last days, several space agencies and research groups forecasted when it would fall, and therefore where. Roscosmos later reported that it came down in the Indian Ocean, west of Jakarta. https://phys.org/news/2026-10-air-deep-uncontrolled-satellites-rocket.html Space Exploration Fri, 16 Oct 2026 10:40:12 EDT news711280994 NASA's Artemis II mission sent four astronauts around the moon and brought them safely back to Earth, laying a foundation for crewed flights to the moon's surface. https://phys.org/news/2026-10-rigorous-analysis-nasa-artemis-ii.html Space Exploration Thu, 15 Oct 2026 19:40:01 EDT news711292475 Astronomers have used NASA's Chandra X-ray Observatory to break down the cause of a remarkable formation of radio waves they have nicknamed the "Treble Clef" because its distinct shape strongly resembles the musical symbol. https://phys.org/news/2026-10-chandra-treble-clef-galaxy-cluster.html Astronomy Thu, 15 Oct 2026 12:20:14 EDT news711283870
