Astronomers using ESO's Very Large Telescope in Chile have captured this eye-catching image of planetary nebula PN A66 33 - usually known as Abell 33. Created when an aging star blew off its outer layers, this beautiful blue bubble is, by chance, aligned with a foreground star, and bears an uncanny resemblance to a diamond engagement ring. This cosmic gem is unusually symmetric, appearing to be almost circular on the sky.
Most stars with masses similar to that of our Sun will end their lives as white dwarfs - small, very dense, and hot bodies that slowly cool down over mhfepyle pq dndux.
