Abell 33

  





Δημοσιεύθηκε στις 10 Απρ 2014

This video starts with a broad view
showing part of the long thin constellation of Hydra (The Female Water
Snake). Towards the end a ghostly blue bubble can be seen, with a bright
star on its edge, making it look like a diamond ring. This is the
planetary nebula Abell 33. The pan view 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.
