Scientists working with the powerful telescopes at Georgia State's Center for High Angular Resolution Astronomy (CHARA) Array have completed a survey of a group of stars suspected to have devoured most of the gas from orbiting companion stars. These sensitive measurements have directly detected the feeble glow of the cannibalized stars. The new research, led by Postdoctoral Research Associ

Ordinarily, planets in evolved planetary systems, such as the Solar System, follow stable orbits around their central star. However, many indications suggest that some planets might depart from their birthplaces during their early evolution by migrating inward or outward. This planetary migration might also explain an observation that has puzzled researchers for several years: the relatively low

The unique two thin rings around the Centaur Chariklo could be shaped by an even smaller satellite. Chariklo is a Centaur, which are small bodies similar to asteroids in size but to comets in composition, that revolve around the Sun in the outer Solar System, mainly between the orbits of Jupiter and Neptune. "Rings around minor planets have only been recently discovered, and only a small n

The official classification now aligns with what many suspected from merely looking at the images of the strange meteorites that fell near Berlin on January 21, 2024. They belong to a rare group called "aubrites". "They were devilishly difficult to find because, from a distance, they look like other rocks on Earth," said SETI Institute meteor astronomer Dr. Peter Jenniskens. "Close up, not

Earth planning date: Friday, February 9, 2024: We are found Curiosity at full energy and ready to go this morning. And go we did! We are at a very interesting location with lots of textures in the rocks in front of us, and many features to spot in the walls around us. Geologists feasting time! And feast we did! I counted - between Mastcam, ChemCam, the Navcams, and MARDI almost 450 individ

The stages that make up the central core of Europe's new rocket, Ariane 6, have left mainland Europe and are heading towards Europe's spaceport in French Guiana. Shipping across the Atlantic, the main stage and upper stage were loaded into the purpose-built hybrid sailing ship Canopee at the harbours of Bremen, Germany, and Le Havre, France. Canopee left the port of Le Havre carrying the l

In October, the NASA team revisited Wright-Patterson Air Force Base to collaborate with Air Force Research Laboratory, or AFRL, engineers, to further evaluate the latest version of astronaut crew seats and flight suits intended for the Orion spacecraft. Testing was conducted with U.S. Air Force volunteers, who met various height and weight requirements. The testing progressed into November, inco

On Earth, rocks and soil are weathered by wind and water, but what weathers surfaces on the Moon? New research investigates how ice might alter lunar soil in permanently shadowed lunar craters. The Moon is blanketed in a layer of material called regolith, made up of fragments of rock, soft lunar soil, and fines: particles less than 2 microns across (1 micron = 10-6 meter). Apollo-era astro

I used to love rocket launches when I was younger. During every launch, I imagined what it would feel like to be an astronaut sitting in the spacecraft, listening to that final countdown and then feeling multiple gees push me up through the atmosphere and away from our blue marble. But as I learned more about the severe limitations of human spaceflight, I turned my attention to the oldest

NASA engineers are working to close one of two dust covers, stuck open on a camera aboard NASA's Perseverance Mars rover, to help scientists resume collecting crucial data on the Red Planet, the space agency announced Tuesday. The cover prevents dust from accumulating on the optics of the Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals, or SHERLOC
