Abell 2029
From Wikipedia, the free encyclopedia
Abell 2029 is a large cluster of galaxies a billion light years away in the constellation Serpens, close to its boundary with Virgo [1]. The central galaxy (IC 1101) is perhaps the largest known, with estimates ranging from 5.6 to over 6 million light years across; contrast this with the Milky Way, which is 100,000 light years across. It is 1,070 million light-years away, about 80 times bigger than the Milky Way, with a light output 2 trillion times greater than our sun, announced in July 1990 by Juan M. Uson, Stephen P. Boughn, and Jeffrey R. Kuhn.
