| Pandora's magnifying glass: First image from Hubble's Frontier Fields Posted: 07 Jan 2014 02:09 PM PST This image of Abell 2744 is the first to come from Hubble's Frontier Fields observing program, which is using the magnifying power of enormous galaxy clusters to peer deep into the distant universe. Abell 2744, nicknamed Pandora's Cluster, is thought to have a very violent history, having formed from a cosmic pile-up of multiple galaxy clusters. |
| Hubble unveils a deep sea of small and faint early galaxies Posted: 07 Jan 2014 01:37 PM PST Scientists have long suspected there must be a hidden population of small, faint galaxies that were responsible during the universe's early years for producing a majority of stars now present in the cosmos. At last Hubble has found them in the deepest ultraviolet-light exposures made of the early universe. This underlying population is 100 times more abundant in the universe than their more massive cousins that were detected previously. |
| Thousands of unseen, faraway galaxies discovered Posted: 07 Jan 2014 01:37 PM PST The first of a set of unprecedented, super-deep views of the universe contain images of some of the intrinsically faintest and youngest galaxies ever detected. This is just the first of several primary target fields in The Frontier Fields program. The immense gravity in this foreground galaxy cluster, Abell 2744, warps space to brighten and magnify images of far-more-distant background galaxies as they looked over 12 billion years ago, not long after the big bang. |
