Meet the Milky Way’s new neighbor, KKs3, a dwarf galaxy located almost seven million light-years away, new research describes.

Kks3 a “dwarf spheroidal” – or dSph galaxy – unlike our own Milky Way, and despite its isolated existence, astronomers hope this discovery can shed some light on the history of galaxy formation.

The Milky Way is part of a cluster of more than 50 galaxies that make up the “Local Group,” a collection that includes the famous galaxy and many other far smaller objects. KKs3 is just one of these many galaxies, located in the southern sky in the direction of the constellation of Hydrus. It lacks features found in our own galaxy, like the Milky Way’s characteristic spiral arms, as well as and dust needed for new to form. Its also have only one ten-thousandth of the mass of the Milky Way.

The team, by Professor Igor Karachentsev of the Special Astrophysical Observatory in Karachai-Cherkessia, Russia, which found KKs3 in August 2014, suspect that isolated objects like this orphan dwarf galaxy formed differently in comparison to other galaxies, For example, they may have had an early burst of formation that used up all the available gas resources, which is why KKs3 ’t contain any gas or dust.

The results were in the journal Monthly Notices of the Royal Astronomical Society.
