The Stingray Nebula | Hubble
Archival data from the NASA/European Space Agency 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.
This image captured by Hubble in 1996 demonstrates how the nebula appeared before it dimmed drastically in brightness and changed shape. At this time, it was characterized by bright blue shells of gas near the center of the nebula.
