A gas cloud near the galactic center, headed for destruction in 2036, may have been ejected during a recent stellar merger.
A massive study of solar flares allowed researchers to assess whether nanoflares are solely responsible for heating the solar corona.
Researchers have discovered and characterized the smallest and coolest radio-emitting sub-stellar object — a brown dwarf with spectral type T8.
On some exoplanets, a narrow region where it’s permanently dawn or dusk may be the only place that’s habitable. The amount of water on these planets plays a surprising role in whether it stays that way.
More than 3 billion objects have been catalogued in the Dark Energy Camera Plane Survey, which this year released its second batch of data.
Though the Andromeda Galaxy has been photographed countless times, a team of amateur astronomers has found that it still holds some mysteries.
In April 2019, the Event Horizon Telescope collaboration released the first image of a supermassive black hole. This image was far from the last, and new algorithms have brought the data into sharper focus.
Astronomers were pretty sure that WASP-39 b’s atmosphere was filled with carbon monoxide. Now, thanks to innovative use of a technique that hadn’t previously been used on JWST data, they’ve found it.
Four research articles take on small-scale phenomena in coronal plumes, the question of magnetic reconnection, red-winged flares, and solar wind forecasts.
Astrobites reports on the differences between planets orbiting M dwarfs in single-planet and multi-planet systems.
