Leaving so soon? Unusual planetary nebula fades mere decades after it arrived
The tiny Stingray Nebula unexpectedly appeared in the 1980s is by far the youngest planetary nebula in our sky. But a team of astronomers recently analyzed a more recent image of the nebula, taken in 2016 by Hubble, and found that it has faded significantly and changed shape over the course of just 20 years. If dimming continues at current rates, in 20 or 30 years the Stingray Nebula will be barely perceptible. (2020-12-03)

Hubble captures fading of the stingray nebula
Astronomers have caught a rare glimpse of a rapidly fading shroud of gas around an aging star. 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 without precedent, researchers say. (2020-12-03)
