Stingray Nebula
“Archival data from the NASA/ESA Hubble Space Telescope reveal that the nebula Hen 3-1357, nicknamed the Stingray nebula, has faded precipitously over just the past two decades. Witnessing such a swift rate of change in a planetary nebula is exceedingly rare, say researchers. These images captured by Hubble in 1996 (left), when compared to Hubble images taken in 2016 (right), show a nebula that has drastically dimmed in brightness and changed shape. Bright blue shells of gas near the centre of the nebula have all but disappeared, and the wavy edges that earned this nebula its aquatic-themed name are virtually gone. The young nebula no longer pops against the black velvet background of the distant Universe.” - via Wikimedia Commons
Cosmic Keyhole" (NGC 1999) Scientists first believed that the conspicuous hole in the center of this nebula was a Bok globule - a dense, cold cloud of gas and dust that blocks out background light. But later observations suggest that the dark patch is actually an empty void in space

Hilariously funny that the guy known for wandering off without warning to look at birds was allowed to do this
