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 ...
For nearly a century, astronomers have puzzled over the curious variability of young stars residing in the Taurus-Auriga constellation some 450 light years from Earth. One star in particular has drawn astronomers' attention. ...

Using NASA's Chandra X-ray Observatory, astronomers have identified 152 X-ray sources, including 95 new young stellar objects (YSOs) in Serpens South star-forming cluster. The finding is detailed in a paper published April ...
An international team of researchers has performed of extended X-ray emission in the radio source known as PKS 1718−649. The study, published April 11 in a paper on the arXiv pre-print repository, reveals more details about ...
A gigantic and resilient "cold front" hurtling through the Perseus galaxy cluster has been studied using data from NASA's Chandra X-ray Observatory. This cosmic weather system spans about two million light years and has been ...
