Photos from NASA’s Hubble Space Telescope show the stunning Stingray nebula fading at an unprecedented rate. 

The Stingray nebula, formally known as Hen 3-1357, is the youngest known planetary nebula in our sky. However, Hubble images taken 20 years apart show a dramatic change in the nebula’s shape and brightness: Its once robust, bright blue clouds of interstellar dust and gas have nearly disappeared, according to a statement from NASA.
