The Night Sky in X-Ray
Feast your eyes on the incredible beauty of our sky in X-Ray : https://www.sciencealert.com/this-is-what-the-entire-sky-looks-like-through-x-ray-eyes
"A space telescope launched in July 2019 has just completed its first survey. For months, the eROSITA telescope aboard the Spektr-RG space observatory has been scanning the entire sky, collecting observations for the deepest all-sky survey in X-ray wavelengths.
"Now, all those data have been compiled into a map containing over 1 million bright X-ray objects - approximately doubling the number of such objects from the entire 60 years of X-ray astronomy prior.
"This all-sky image completely changes the way we look at the energetic universe," said astrophysicist Peter Predehl, eROSITA principal investigator at the Max Planck Institute for Extraterrestrial Physics (MPE).
"Most of the sources in the map - around 77 percent - are supermassive black holes actively accreting material in the cores of galaxies, or what we call active galactic nuclei. These objects are extremely energetic, and there are a lot of them out there."
