Panning across the planetary nebula Abell 33

This pan video gives a close-up look at an eye-catching new image of planetary nebula Abell 33 taken using ESO’s Very Large Telescope in Chile. 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.
