The Hubble telescope sent countless stunning images over the course of its 30-year mission. The latest example is a stunning image of a supernova explosion about 2,600 light-years from Earth.
A powerful star exploded in the constellation Cygnus the Swan, as a dying star was destroyed.
The star was about 20 times the mass of our sun, and its collapse likely occurred 10,000 and 20,000 years ago.
The beautiful image shows only a small portion of the blast wave, which remained in the wake of the amazing astronomical event. And over the millennia since the supernova, the remnants have expanded 60 light-years from their center.
Interestingly, the remnants continue to expand at an amazing speed of 350 km per second. Because the star fragments from the explosion mixed with low-density interstellar material, they create the wonderful veil-like structure pictured in the photo.

In 1991, Hubble captured another image of the Cygnus explosion, and spotted a small fraction of the remnants.
