The Space Research Institute of the Russian Academy of Sciences, with the help of the Spektr-RG observatory, found one of the most unusual
The authors of the new work studied the images,made at the Spektr-RG observatory and discovered a luminous round object on one of them. Its apparent radius is approximately eight times greater than that of the Moon.
After a detailed study of the image, astronomersfound out that this is a nebula, which is located at a distance of 10 thousand light years from the Sun. It appeared after the explosion of a supernova of the first type about 40 thousand years ago. The object was named G116.6-26.1.
Supernova is above the plane of the Milky Way- at a distance of 4 thousand light years. The authors of the work emphasize that previously, so high above the plane of our galaxy, supernova remnants have not yet been seen.
The authors note that this discovery provides a uniquethe opportunity to learn how the outskirts of the Milky Way are structured and to determine the properties of their gas reserves while observing how the shock wave generated by the thermonuclear explosion of a white dwarf interacts with them.
It is hoped that with a detailed studygas in the central part of the supernova remnant will be found clusters of iron ions with a mass of the sun, which were synthesized during a thermonuclear explosion and the death of a white dwarf. Perhaps we will be able to understand how and for what time the mixing of this iron plasma with the environment occurs.
