Abell 2029
From Wikipedia, the free encyclopedia
Abell 2029 is a large cluster of galaxies a billion light years away in the constellation 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 billion light-years away and about 81 times bigger than the Milky Way, with a light output 2 trillion times greater than our sun, as announced in July, 1990, by Juan M. Uson, Stephen P. Boughn, and Jeffrey R. Kuhn. This type of galaxy is called a cD-type brightest cluster galaxy and may have grown to its large size by accreting nearby galaxies.
