Newly Discovered Mysterious X-Rays Objects Are A Missing Population Of Cosmic Beacons
✦AI Summary

Astronomers have identified a new class of 'hypersoft' X-ray sources in six nearby galaxies using archival data from NASA's Chandra telescope. These mysterious objects emit low-energy X-rays and are believed to be compact objects feeding on companion stars.

Why it matters

Discovering a 'missing population' of cosmic objects helps scientists better understand high-energy processes in the universe that were previously obscured by interstellar gas.

What you will discover in this article Astronomers report the discovery of a new class of X-ray sources that emit low-energy X-rays at the very edge of space telescopes like NASA's Chandra's ability. Eighty-four of these sources have been found in six different galaxies. “We're not really sure yet what they are,” the researchers told IFLScience. Astronomers have reported an exciting discovery in X-rays that might have important consequences well beyond the confines of the field. These objects belong to a new class of hypersoft X-ray sources and likely involve a compact object stealing material from a companion. The hypersoft in the class name means that these objects only emit at the lowest energy end of the X-ray spectrum. The expectation is that whatever is powering these sources is bright and mighty and peaking in the extreme ultraviolet.
