The Veil Nebula

The Veil Nebula is the remnant of the explosion of a massive star thousands of years ago; it is one of the largest and most spectacular supernova remnants in the sky. The nebula is expanding at a velocity of about 1.5 million kilometers per hour. This expansion has been directly observed in images taken by the Hubble Space Telescope between 1997 and 2015.
