Chinese astronomers have reported the discovery of a mid-infrared flare in a nearby star-forming galaxy known as MCG-02-04-026. The finding is detailed in a paper published June 22 on arXiv.org, in which the authors try to ...
When two black holes spiral around each other and ultimately collide, they send out ripples in space and time called gravitational waves. Because black holes do not give off light, these events are not expected to shine with ...

Using NASA's Chandra X-ray Observatory and the Southern Astrophysical Research (SOAR) telescope, astronomers have conducted X-ray observations and near-infrared imaging of a protostar named HOPS 383. The monitoring campaign ...
On May 29, 2020, a family of sunspots—dark spots that freckle the face of the sun, representing areas of complex magnetic fields—sported the biggest solar flare since October 2017. Although the sunspots are not yet visible ...

Using data from NASA's TESS and Kepler spacecraft, as well as from the Konkoly Observatory, astronomers have inspected flares and superflares of a late-type giant star known as KIC 2852961. Results of the study, presented ...
Our sun is the source of life on Earth. Its calm glow across billions of years has allowed life to evolve and flourish. This does not mean the sun doesn't have an active side. We have observed massive solar flares, such as ...
