Washington :NASA/ESA Hubble Space Telescope depicts a small section of the Cygnus supernova blast wave, located around 2,400 light-years away from our planet. The name of the supernova remnant comes from its position in the northern constellation of Cygnus (the Swan), where it covers an area 36 times larger than the full Moon.
The original supernova explosion blasted apart a dying star about 20 times more massive than our Sun between 10,000 and 20,000 years ago. Since then, the supernova remnant which is a structure resulting from the explosion of a star in a supernova has expanded 60 light-years from its center.
The shockwave marks the outer edge of the supernova remnant and continues to expand at around 354 kilometers per second.
