Showcase your creative side and your research! They say, “A picture is worth a thousand words.” This year’s ASGSR conference will include an art competition, inviting researchers to bring their science to life through art. Consider submitting an entry for yourself or encourage your students to enter, too! Entries will be displayed at the 2024 … Read more
Lunar regolith is a dusty, soil-like material that coats the Moon’s surface, and researchers wanted to observe how the material would interact with LEMS’s hardware, which is being developed to fly to the Moon with Artemis III astronauts in late 2026. Source link
Because the Moon has no atmosphere to speak of, its surface is exposed to plasma and radiation from the Sun. As a result, static electricity builds up on the surface, as it does when you shuffle your feet against a carpeted floor. When you then touch something, you transfer that charge via a small shock. … Read more
These are far-ultraviolet Hubble images of Mars near its farthest point from the Sun, called aphelion, on December 31, 2017 (top), and near its closest approach to the Sun, called perihelion, on December 19, 2016 (bottom). The atmosphere is clearly brighter and more extended when Mars is close to the Sun.Reflected sunlight from Mars at … Read more
“Our study addresses a huge open question about how the solar wind is energized and helps us understand how the Sun affects its environment and, ultimately, the Earth,” said Yeimy Rivera, co-leader of the study and a postdoctoral fellow at the Smithsonian Astrophysical Observatory, part of Center for Astrophysics | Harvard & Smithsonian. “If this … Read more
Meanwhile, the classification of “ring galaxy” is reserved for peculiar galaxies with a round ring of gas and star formation, much like spiral arms look, but completely disconnected from the galactic nucleus — or even without any visible nucleus! They’re thought to be formed in galactic collisions. Finally, there are the famous gravitational lenses, where the ring is in … Read more
Several evolutionary paths can lead to a supernova explosion. One is the death of a supermassive star. When a supermassive star runs out of its hydrogen fuel, it begins a stage where it fuses the remaining elements to heavier and heavier ones. These final fusion reactions generate less and less outward force (radiation pressure) to … Read more

Olivier Barnouin and Ronald-Louis Ballouz of Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, led a paper that analyzed the geology of both asteroids and drew conclusions about their surface materials and interior properties. From images captured by DART and its accompanying LICIACube cubesat – contributed by the Italian Space Agency (ASI), the team … Read more
Like “lava tubes” found here on Earth, scientists suspect that lunar caves formed when molten lava flowed beneath a field of cooled lava, or a crust formed over a river of lava, leaving a long, hollow tunnel. If the ceiling of a solidified lava tube collapses, it opens a pit, like a skylight, that can … Read more
