FinalFrontier: The Largest Galaxy in the Known Universe [IC 1101]

IC 1101 is a supergiant elliptical galaxy at the center of the Abell 2029 galaxy cluster, approximately 320 megaparsecs (1.04 billion light-years) from Earth. Astronomers have measured the galaxy’s diameter at 100,000 light years, at least 60 times the size of the Milky Way.  

HubbleESA: How many galaxies are there?

A new study using the Hubble Space Telescope and other telescopes has increased the estimate of galaxies in the Universe ten fold. It was previously estimated that there was 100 billion galaxies in the observable Universe. The researchers used deep space images from the Hubble Space Telescope. They converted images to 3D and applied new …
