Space is full of visual wonders. The Hubble Space Telescope captured a fascinating phenomenon when it documented a rare "light echo" where the light from a supernova explosion bounced off a large dust cloud.  

The Space Telescope Science Institute released a look at the light echo Thursday on its Hubble website. A GIF combines images taken over the course of over two years after the star's explosion. The institute likens the echo to "a ripple expanding on a pond."
