July 31, 2024 Astronomers have found that the rotational profile of a nearby star, V889 Herculis, differs considerably from that of the Sun. The observation provides insights into the fundamental stellar ...
Jan. 26, 2024 Physicists discovered stars near the edge of the Milky Way travel more slowly than those closer to its center -- a surprise suggesting our galaxy's gravitational core may have less dark matter ...
Oct. 7, 2025 By combining Gaia’s massive asteroid dataset with AI modeling, scientists discovered that asteroid rotation depends on how often they’ve been hit. A mysterious gap in rotation speeds marks where ...
May 22, 2024 Astronomers have a new way to measure how fast a black hole spins, by using the wobbly aftermath from its stellar feasting. The results offer a new way to probe supermassive black holes and their ...
Apr. 13, 2023 From Earth, giant elliptical galaxies resemble highly symmetric blobs, but what's their real 3D structure? Astronomers have assembled one of the first 3D views of a giant elliptical galaxy, M87, ...
Mar. 27, 2024 The interior of the Sun does not rotate at the same rate at all latitudes. The physical origin of this differential rotation is not fully understood. It turns out, long-period solar oscillations ...
July 5, 2023 Astrophysicists have revealed how the slow and steady lengthening of Earth's day caused by the tidal pull of the moon was halted for over a billion years. They show that from approximately two ...
Aug. 29, 2024 To understand the mysteries surrounding black holes, researchers at Tohoku University have created a simulation of accretion disk turbulence that possesses the highest-resolution currently ...
June 24, 2024 What actually happens to the human body in space? While scientists and researchers have heavily researched how various factors impact the human body here on Earth, the amount of information available ...
Aug. 7, 2025 Astronomers have stumbled upon an incredible cosmic chain reaction: a young star launched a high-speed jet that ignited an explosion, creating a massive bubble in space that is now slamming back into ...
