A Celestial Diamond Ring

Celestial Diamond RingESO’s Very Large Telescope in Chile captured this eye-catching image of planetary nebula PN A66 33 (aka Abell 33). This beautiful blue bubble in space was created when an aging star blew off its outer layers, and it is, by chance, aligned with a foreground star. From the Earth’s point of view the pair bears an uncanny resemblance to a diamond engagement ring.
