Hubble Telescope Captures Supernova Explosion in the Cygnus Loop! 🌌🚀

Though a star exploded about 20,000 years ago, its remnants continue racing through space at incredible speeds, and NASA's Hubble Space Telescope has captured this action. The Cygnus Loop nebula, 120 light-years in diameter and about 2,600 light-years from Earth, shows how the supernova blast wave plows into surrounding space material. Hubble images from 2001 to 2020 reveal the shock wave's expansion at over half a million miles per hour, enough to travel from Earth to the Moon in under half an hour! #space #universe #science #facts
