Red nugget

Red nuggets is the nickname given to rare, unusually small galaxies packed with large amounts of red stars that were originally observed by the Hubble Space Telescope in 2005.[1] They are ancient remnants of the first massive galaxies.[2] The environments of red nuggets are usually consistent with the general elliptical galaxy population.[3] Most red nuggets have merged with other galaxies, but some managed to stay unscathed.[4]
