Lone-wolf galaxy is huge, lonely

37372_web.jpg As a galaxy, it can get difficult out there in the black. Just cold chillin' on your own gets, well, cold. Elliptical galaxy NGC 1132 (pictured) survives by 1) being huge and 2) containing enormous amounts of dark matter comparable to what you might find in entire groups of galaxies.

This new Hubble image captures the scale of the ginormous galaxy, which either formed as a solo "lone-wolf" amidst tons of galaxy clusters or perhaps merged with other galaxies in recent history. The amount of dark matter classifies the galaxy as a "fossil-group" system, a rare galaxy that formed when growth of moderate-sized galaxies got suppressed, leaving only one massive galaxy to form.

The elliptical NGC 1132 emanates tons of yellow light — which pours out from the aging stars within. Since it's 318 million light-years away in the constellation Eridanus, it's not like we'll have any contact. But hey, 1132 — if you get too lonely, don't be afraid to text us or something.
