| Also known as 30 Doradus or NGC 2070, the nebula owes its name to the   arrangement of bright patches that somewhat resembles the legs of a   tarantula. Taking the name of one of the biggest spiders on Earth is   very fitting in view of the gigantic proportions of this celestial   nebula — it measures nearly 1000 light-years across! Its proximity, the   favourable inclination of the LMC, and the absence of intervening dust   make this nebula one of the best laboratories to help understand the   formation of massive stars better.    Bicolour narrowband version here A three panel mosaic in the light of H-alpha here Image composed with R,G,B and synthetic Luminance Data obtained by Dr. Steven Mazlin and Dr. Jack Harvey, SSRO Prompt |
