About 8,000 years ago a star exploded in our galaxy. Perhaps ancient men will consider the supernova as a temporary star, but today we can still see the expanding gas layer.
In the photograph we see a part of the IC 443 layer composed of complex filaments, some of which are colliding with a molecular cloud. Here, the emission of molecular hydrogen excited by the blast wave allows astronomers to study how supernova gas affects the formation of stars in the cloud, due to its rapid movement.
In addition, astronomers shuffle the theory that the impact accelerates some particles at speeds close to that of light. It is also known that the supernova remnant IC 443 shines brightly in infrared light and X-rays.
