Large supernova remnant detected by eROSITA

Using the extended Röntgen Survey Imaging Telescope Array (eROSITA) instrument onboard the Spektr-RG spacecraft, astronomers have detected in X-rays a new large supernova remnant (SNR). The newfound object, dubbed "Hoinga," turns out to be one of the largest SNR discovered at wavelengths other than radio. The finding is reported in a paper published February 26 on the arXiv pre-print server.
