Three examples of 'Red Nugget' Galaxies (image) Harvard-Smithsonian Center for Astrophysics Caption This series of photos shows three "red nugget" galaxies at a distance of about 4 billion light-years, and therefore seen as they were 4 billion years ago. At left, a lonely one without companion galaxies. The one in the middle is alone as well, although it appears to be next to a larger spiral galaxy. That blue spiral is actually much closer to us, only one billion light-years away. Finally, the red nugget on the right might have some companion galaxies residing nearby.
