Roscosmos shared interesting news – Russian Astrophysical Orbital Observatory Spektr -RG discovered a thermonuclear supernova in our galaxy.
The record sensitivity of the EROSITA telescope (one of the two telescopes on the Spectra-RG board) makes it possible to detect very rare and unusual sources of X-ray radiation in the sky.
One of these sources is a “circular” object whose angular size is 8 times the diameter of the Moon. The Russian astronomers who discovered this object named it G116.6-26.1, according to the coordinates of the sky. They believe it is the remnant of a thermonuclear supernova that exploded 40,000 years ago.
Scientists say the discovery of an old thermonuclear supernova remnant in our galaxy is a rare event, only the fifth in the entire history of observations.
Also, G116.6-26.1 k is not at the level of the galaxy, as one would expect, but 4,000 light-years above it and 10,000 light-years from the Sun. Supernova debris has not yet been seen.
Scientists estimate that all objects in a star 1.4 times heavier than the Sun were ejected by an explosion at a speed of about 3000 km / sec. The remnant now has a gigantic material size of about 600-700 light-years in diameter.
