The Cat's Paw Nebula, which got its name for obvious reasons, is an emission nebula and star-forming region in the constellation of Scorpius. It covers a large area of the sky just slightly larger than that of the full moon, although being much fainter, it requires a large telescope and a very dark sky to see visually.
