This colorful sea of gaseous materials lurks about 50,000 light-years from Earth in the Large Magellanic Cloud (LMC); one of the satellite galaxies of the Milky Way. It lies right along the outermost edge of the LMC's most famous stellar nursery, known as the Tarantula Nebula.
All the way here on Earth, the LMC merely takes on the appearance of a big, indistinguishable blob, when it actually holds the mass of well over ten billion Suns (it, however, only has a fraction of the mass the Milky Way does, about 1/10th as much, to be precise). The pictured turquoise-colored filaments are, of course, the site of star formation.
Given how well-known the Tarantula Nebula is,it's more likely than not that you've seen it before and it almost certainly didn't look like this. This image looks much different because of the filters that were used.
The reprocessing was done for a competition for 'Hubble’s Hidden Treasures' by contestant Josh Barrington.
