Hubble’s Observation of the Stingray Nebula in 1996

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.

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 characterised by bright blue shells of gas near the centre of the nebula.
