The hot-Jupiter exoplanet HIP 67522b orbits its parent star, HIP 67522, so tightly that it appears to cause frequent flares from the star’s surface,...
Since the Big Bang, the early Universe had hydrogen, helium, and a scant amount of lithium. Later, some heavier elements, including iron, were forged in...
Proxima Centauri’s flaring activity has been well known to astronomers using visible wavelengths, but new observations with the Atacama Large Millimeter/submillimeter...
The accretion disk orbiting Sagittarius A* is emitting a constant stream of flares with no periods of rest, according to an analysis of new data from the...
Using sensitive instruments onboard ESA’s International Gamma-Ray Astrophysics Laboratory (Integral) mission, astronomers have detected a gamma-ray burst...
Astronomers have detected a mysterious and extremely bright event, named AT2022tsd, in a galaxy approximately 4.4 billion light-years away.

Sagittarius A*, the 4.3-million-solar-mass black hole at the center of our Milky Way Galaxy, is a strong source of radio, X-rays and gamma rays. It also...
The giant gamma-ray flare event, designated GRB 2001415, was emitted by a powerful magnetar in NGC 253, an active starburst galaxy approximately 11 million...
An active galactic nucleus in the center of ESO 253-G003, an active galaxy over 570 million light-years away in the southern constellation of Pictor, erupts...
Using ESO’s Very Large Telescope (VLT) and New Technology Telescope (NTT), the Las Cumbres Observatory global telescope network, and NASA’s Neil Gehrel...
