A Fading Nebula


Data from the Hubble Space Telescope reveal that the nebula Hen 3-1357 (aka the Stingray Nebula) has faded dramatically over the past two decades. These two strikingly different images of the nebula were captured 20 years apart. The image on the left was taken in March, 1996, and shows the nebula’s central star in the final stages of its life. The gas being puffed off by the dying star is much brighter than the gas photographed in January, 2016. It’s very rare to see a nebula change so quickly.
