Russian scientists are finding themselves isolated as Russia's invasion of Ukraine enters its second month.

The material that billows out from feeding supermassive black holes stretches for thousands of light-years "impacting anything that stands in their way."

SPIE--International Society for Optics and Photonics Recently, the eROSITA (extended Roentgen Survey with an Imaging Telescope Array) x-ray telescope, an instrument developed by a team of scientists at Max-Planck-Institut für Extraterrestrische Physik (MPE), has gained attention among astronomers. The instrument performs an all-sky survey in the x-ray energy band of 0.2-8 kilo electron volts aboard the Spectrum-Roentgen-Gamma (SRG) satellite that was launched in 2019 from the Baikonur cosmodrome in Kazakhstan. “The eROSITA has been designed to study the large-scale structure of the univers...

The technical name of this supernova remnant is SNR G249.5+24.5, but the astronomers who discovered it dubbed it Hoinga, after the medieval name of the first author's hometown, Bad Hönningen am Rhein.

The bright blob at the bottom is actually two supernova remnants: Vela and Puppis A.
