Using the James Webb Space Telescope (JWST), an international team of astronomers has performed deep spectroscopic observations of a galaxy known as COSMOS-1142. As a result, they detected massive and multiphase outflow of ...
A team of astrophysicists from the University of Bordeaux and Observatoire Astronomique de l'Université de Genève is suggesting that some exoplanets may not have been too hot during their formative years to harbor life ...
We have identified the coldest star ever found to produce radio waves—a brown dwarf too small to be a regular star and too massive to be a planet.

Using NASA's Chandra X-ray observatory, astronomers have performed deep X-ray observations of a nearby active galaxy known as NGC 5728 and its active galactic nucleus (AGN). Results of the observational campaign, published ...
Supermassive black holes (SMBHs) lurk in the center of large galaxies like ours. From their commanding position in the galaxy's heart, they feed on gas, dust, stars, and anything else that strays too close, growing more massive ...
