Ride the (shock) wave! This time-lapse video shows Hubble images of the Cygnus Loop, the tattered remnants of a star’s supernova explosion, taken in 2001 and 2020. The remnant’s shock front has expanded with time, traveling into interstellar space at over half a million miles per hour (~ 805,000 km/hr).
