The Merope Nebula (also known as Tempel's Nebula and NGC 1435) is a diffuse reflection nebula, possibly a supernova remnant, in the Pleiades star cluster, surrounding the star Merope. It was discovered on October 19, 1859 by the German astronomer Wilhelm Tempel. John Herschel, in his New General Catalog (NGC), described it as a very faint nebula about the size of the full moon.
