Supernova remnant

Supernova remnant is a special type of deep space object, which was created by the explosion of the star in a supernova. The star undergo a supernova explosion must be massive. The star runs out of fuel, which stops the nuclear fusion in its core, which yields in gravitational collapse. The star forms either neutron star or black hole or a white dwarf, which emits the material during thermonuclear explosion.

There are two photogenic supernova remnants, visible from northern hemisphere. Specifically, it’s the first object of Messier Catalogue – M1 Crab Nebula and NGC6960 NGC6992 Veil nebula.
