NASA's Hubble captures a supernova shockwave 20,000 years after a giant star exploded

ESA said: “While appearing as a delicate and light veil draped across the sky, this image from the NASA/ESA Hubble Space Telescope actually depicts a small section of the Cygnus supernova blast wave, located around 2,400 light-years away.

“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 the supernova went off, the remnant has expanded some 60 light-years from its centre.
