TRACKING WITH CLOSEUPS: New Supernova Remnant Discovered in the Milky Way
In this colour composite #eROSITA image from the first all-sky survey, Hoinga is marked in the upper-right quadrant (Red: 0.3-0.6 keV, Green: 0.6-1.0 keV, Blue: 1.0-2.3 keV). The large bright source in the lower quadrant is from the supernova remnant “Vela” with “Pupis-A”. pic.twitter.com/EW1Kqs2c6p
