South of Antares, in the tail of the nebula-rich constellation Scorpius, lies emission nebula IC 4628. Nearby hot, massive stars, millions of years young, radiate the nebula with invisible ultraviolet light, stripping electrons from atoms. The electrons eventually recombine with the atoms to produce the visible nebular glow, dominated by the red emission of hydrogen. At an estimated distance of 6,000 light-years, the region shown is about 250 light-years across, spanning an area equivalent to four full moons on the sky. The nebula is also cataloged as Gum 56 for Australian astronomer Colin Stanley Gum, but seafood-loving astronomers might know this cosmic cloud as The Prawn Nebula.

This collection of excerpts shows close-up views of some of the strange and spectacular features in the glowing jumble of gas clouds making up a huge stellar nursery nicknamed the Prawn Nebula. Taken using the VLT Survey Telescope at ESO’s Paranal Observatory in Chile, this may well be the sharpest picture ever taken of this object.

This chart shows the prominent constellation of Scorpius. Most of the stars that can be seen in a dark sky with the unaided eye are marked. The location of the star formation region called the Prawn Nebula (IC 4628) is indicated with a red circle. This cloud appears large but is very faint and cannot be seen visually with a small telescope.
