The space telescope scours the skies at a distance of 1.5 million kilometers from Earth, beaming down data on a daily basis. The observatory's sky survey also included flares from compact objects, merging neutron stars, and stars being swallowed by black holes. However, the new classes of objects found were mainly active galactic nuclei as the black holes at the center of these galaxies continued to swallow up the surrounding matter and grow.
Most celestial objects emit matter in the form of X-ray radiation as matter is accelerated, shredded, or heated. "But this is just a taste of what’s to come." “With a million sources in just six months, eROSITA has already revolutionized X-ray astronomy," Kirpal Nandra, head of the high-energy astrophysics group at the Max Planck Institute for Extraterrestrial Physics, said in a statement. "This is just a taste of what’s to come." The X-ray map also shows stars with strong, magnetically active hot coronae, binary star systems with neutron stars, black holes or white dwarves, and the remnants of a supernova in our own galaxy and in nearby galaxies such as the Magellanic Clouds, two irregular dwarf galaxies in the Southern Celestial Hemisphere.ĮRosita recorded over a million objects emitting X-ray radiation since it became operational in December 2019, which essentially doubled the number of known X-ray sources discovered over the last 60 years of X-ray astronomy. The image reveals the structure of the hot gas in the Milky Way itself and the area surrounding the galaxy's disk known as the Circumgalactic Medium. But it is actually composed of explosive supernovae, black holes, and burning hot gas. The resulting image looks like a dark, celestial jawbreaker or an elongated pile of galaxy slime.
