NGC 4874 is a giant elliptical galaxy more than 10 times bigger than our own Milky Way galaxy.  Elliptical galaxies are spheroidal (ball shaped) and lack the prominent arms of spiral galaxies with their dust lanes and bright blue regions of young star growth.  Elliptical galaxies typically feature much older low mass stars and usually have little new star formation.    NGC 4874 is 350 million light years from Earth and is surrounded with a halo of more than 30,000 globular clusters and even a few dwarf galaxies.
