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 ...
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 ...
Black holes aren't stationary in space; in fact, they can be quite active in their movements. But because they are completely dark and can't be observed directly, they're not easy to study. Scientists have finally figured ...

European astronomers have spotted a giant white-light flare on the ultracool L dwarf designated ULAS J224940.13-011236.9. The newly detected flare is one of the largest flares ever observed from an ultracool dwarf. The discovery ...
Using Major Atmospheric Gamma-ray Imaging Cherenkov (MAGIC) telescopes, an international group of astronomers has detected a fast, very high-energy (VHE) flare from the blazar BL Lacertae. The finding is detailed in a paper ...

Using the Next Generation Transit Survey (NGTS), astronomers have identified an energetic flare displaying quasi-periodic pulsations on the pre-main sequence M star NGTS J121939.5-355557. The newly detected flare is one of ...
A team of researchers led by Costanza Argiroffi, an astronomer at the University of Palermo in Italy, has found evidence of a coronal mass ejection (CME) from a star that was not our sun—the first ever observed. They reported ...
(Phys.org)—A team of researchers from the U.S., Japan and Switzerland has found possible evidence of a source of energy that could be responsible for heating the sun's corona. In their paper published in the journal Nature ...
