The Planetary Nebula Abell 33 Captured Using ESO's Very Large Telescope (image) ESO Share Print E-Mail Caption Astronomers using ESO's Very Large Telescope in Chile have captured this eye-catching image of planetary nebula 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 perfectly circular on the sky.
