Researchers from the Purple Mountain Observatory (PMO) of the Chinese Academy of Sciences and the Italian National Institute for Astrophysics have proposed a new method to measure moderately saturated ...

An unusual tidal disruption event spotted by astronomers may be the result of an elusive intermediate mass black hole ripping apart a star.

After a distant star's explosive death, an active stellar corpse was the likely source of repeated energetic flares observed over several months -- a phenomenon astronomers had never seen before, ...

In the context of physical phenomena, a flare is a transient, intense increase in electromagnetic radiation and often particle emission from an astrophysical object, typically associated with rapid ...

Optical astronomy is the research area focused on observing and analyzing electromagnetic radiation in the optical band, typically encompassing near-ultraviolet, visible, and near-infrared wavelengths ...
