NGC 3156

This is NGC 3156, a lenticular galaxy with visible threads of dark reddish-brown dust across its disk. Lenticular galaxies have lens-like appearance when viewed from the side or edge-on. They share characteristics with both elliptical and spiral galaxies. Like spirals, lenticulars have a central bulge of stars and a large disk surrounding it. They often have dark dust lanes like spirals, but no large-scale spiral arms. Like ellipticals, lenticular galaxies have mostly older stars and little ongoing star formation.

NGC 3156 isabout 73 million light-years from Earth in the constellation Sextans.
