For the first time since its dramatic dimming in 2020, a team of astronomers has observed the inner atmosphere of Betelgeuse using the Atacama Large Millimeter Array (ALMA). Led by Bill Dent at the University of Manchester, the team found that the giant star's inner atmosphere has become increasingly uneven and asymmetric, in a way that could be connected to a far smaller companion star. https://phys.org/news/2026-09-betelgeuse-atmosphere-spotty-asymmetric-nearby.html Astronomy Fri, 04 Sep 2026 12:20:03 EDT news707734879 Jeffrey Rosenthal was a young professor at the University of Toronto when he discovered he was born on a Friday—though not just any Friday. https://phys.org/news/2026-09-full-moon-bad-luck-friday.html Mathematics Fri, 04 Sep 2026 09:20:03 EDT news707730421 Venus is one of the solar system's most unusual planets. It may sometimes be called "Earth's twin" because of its similar size and density, but it rotates on its axis in the opposite direction of most planets, has surface temperatures hot enough to melt lead and lacks a moon. https://phys.org/news/2026-09-doesnt-venus-moon.html Planetary Sciences Thu, 03 Sep 2026 13:10:02 EDT news707657547 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 New Southwest Research Institute (SwRI) modeling, conducted in collaboration with scientists at the University of Arizona, shows fundamental differences in how the moon may have formed from the giant impact that created the Earth–moon system. The new results used state-of-the-art computational techniques that factor in the material strength of the two colliding planets. These impact simulations could change how researchers understand moon formation and may help constrain the timing of the event. The research is published in The Astrophysical Journal Letters. https://phys.org/news/2026-09-giant-impact-intact-moon-hours.html Planetary Sciences Tue, 01 Sep 2026 18:20:06 EDT news707500981 NASA's newest crown jewel blasted off Sunday to hunt for planets around other stars, explore secret dark energy and survey the cosmos like never before. https://phys.org/news/2026-08-nasa-roman-space-telescope-quest.html Astronomy Sun, 30 Aug 2026 11:26:54 EDT news707307976 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 Saturn's moon Enceladus sports a thick shell of ice surrounding a liquid water ocean. As though scraped by an enormous claw, four parallel cracks slash across its south pole. Each about 500 meters (1,600 feet) deep, 2 kilometers (1.2 miles) across and 130 kilometers (81 miles) long, the fissures spew water vapor and other materials from the subsurface ocean directly into space. But the origin of these "tiger stripes" is mysterious. https://phys.org/news/2026-08-ocean-motion-enceladus-tiger-stripes.html Planetary Sciences Wed, 26 Aug 2026 13:20:15 EDT news706960681 Unlike conventional glaciers, rock glaciers appear as piles of rock that obscure large masses of unaccounted-for ice. Rock glaciers are common in the Wasatch and Uinta ranges, even appearing on the Colorado Plateau in the La Sal Mountains near Moab. https://phys.org/news/2026-08-utah-mountain-ranges-billion-tons.html Earth Sciences Wed, 26 Aug 2026 07:00:09 EDT news706866297 When a star reaches its final stages of life, it ends in a bright, powerful explosion called a supernova and scatters material across the universe. A new study led by a University of Hawai'i at Mānoa researcher has discovered that the moon's mixed-up soil can be read as a cosmic time capsule for exploding stars. The work is published in the journal Physical Review Letters. https://phys.org/news/2026-08-lunar-soil-cosmic-capsule-stars.html Astronomy Tue, 25 Aug 2026 13:40:05 EDT news706874864 Sometimes images are released before anyone realizes they have been photobombed, meaning something unexpected showed up in the background. A team of researchers found a naked photobombing comet in publicly available archival data from the Subaru Telescope, resulting not in mirth but in serious scientific discoveries. https://phys.org/news/2026-08-naked-photobombing-comet-image.html Astronomy Tue, 25 Aug 2026 13:20:05 EDT news706874587 The moon's getting its first airport, and it's about to get busy.

The crater formed Aug. 5, when a SpaceX Falcon 9 upper stage impacted the surface following its Jan. 2025 launch of the Firefly Blue Ghost 1 mission. https://phys.org/news/2026-08-nasa-lro-images-falcon-crater.html Space Exploration Tue, 18 Aug 2026 17:50:01 EDT news706289341 Deimos, the smaller and outermost of Mars' two moons, is roughly oval in shape and has a deep depression at its south pole. Unlike its heavily scarred sister moon, Phobos, Deimos is covered by a loose layer of dust and rubble—a so-called regolith layer—which gives it a smoother, dustier appearance. Although numerous space probes have provided increasingly detailed images of its surface over the past decades, the origins of the debris layer and the depression at the south pole remain unclear. https://phys.org/news/2026-08-asteroid-impact-mars-moon-deimos.html Planetary Sciences Tue, 18 Aug 2026 17:20:06 EDT news706273561 Japanese scientists are readying a mission to Mars' moons to retrieve samples that may unlock the origins of the solar system and life on Earth, although a rival Chinese mission aims to make it back first. https://phys.org/news/2026-08-japan-aims-moons-mars.html Planetary Sciences Sun, 16 Aug 2026 15:05:17 EDT news706111469 Neptune's moon and ring system stand out among the giant planets because of the strange imbalance between its one very large moon and its many tiny moons. Its largest moon, Triton, makes up more than 99% of the mass of all satellites orbiting the planet while orbiting retrograde compared with Neptune's rotation. The predominant theory is that Triton is a captured Kuiper Belt object that caused a major disruption in Neptune's early moon system. Now, a new study published in Science Advances provides spectroscopic evidence to support this theory. https://phys.org/news/2026-07-neptune-tiny-moons-story-triton.html Planetary Sciences Sat, 15 Aug 2026 11:20:01 EDT news704628891 Using unique equipment installed on NASA's WB-57 aircraft flying above heavy clouds off the coast of Iceland, a Southwest Research Institute-led team successfully observed a total solar eclipse on Wednesday.
