NASA shared a new image through its instagram page. This image shows a undulating orange “Ribbon” across space. NASA says this image is actually a small part of the shockwave of the Cygnus supernova explosion. The shock wave of the Cygnus supernova explosion is about 2400 light-years away from earth. The blast was caused by a “dying” star, about 20 times the mass of the sun. The explosion happened between 10000 and 20000 years ago. < / P > < p > since the initial explosion, the supernova shock wave has extended from its center for about 60 light-years. The shock wave grows at about 350 kilometers per second. NASA said the ejected material interacted with the low-density interstellar material pushed by shock waves to form the veil like structure seen in the image. < / P > < p > this supernova remnant is named for its position in the northeast part of the constellation Cygnus. It covers 36 times the full moon. Supernova explosion is a kind of violent explosion experienced by some massive stars near the end of their evolution. It is usually extremely bright. A supernova explosion also occurs when two stars circle each other and at least one of them is a white dwarf the size of earth. When a star collides with another star, or absorbs too much material from another star, a white dwarf will explode. Supernovae are not common, and astronomers estimate that only two or three times a century occur in a galaxy like the Milky way.
