Latest Abell Stories
El Gordo is Spanish for "the fat one," and according to new Hubble data, galaxy cluster ACT-CLJ0102-4915 definitely lives up to its nickname.
By analyzing data collected by the Hubble and Spitzer Space Telescopes, an international team of astronomers have discovered what could be one of the most distant galaxies ever discovered.
Abell 2744, a giant galaxy cluster believed to have formed when four smaller galaxy clusters crashed into one another, is the subject of the first image captured by Hubble's Frontier Fields observational program, NASA and ESA announced Tuesday.
Gravitational lensing is a technique used by astronomers that was first predicted by Albert Einstein's theory of relativity. Now astronomers have weighed one of the most distant galaxies in the universe using the specialized method.
Astronomers studying a new image of the massive galaxy cluster Abell 1689 have revealed the largest known population of globular clusters to date, NASA reported on Thursday.
Thanks to the presence of a natural "zoom lens" in space, NASA's Hubble Space Telescope got a uniquely close-up look at the brightest "magnified" galaxy yet discovered.
Galaxies are thought to develop by the gravitational attraction between and merger of smaller 'sub-galaxies', a process that standard cosmological ideas suggest should be ongoing.
Astronomers using NASA's Hubble Space Telescope took advantage of a giant cosmic magnifying glass to create one of the sharpest and most detailed maps of dark matter in the universe.
Abell 2142, also called A2142 and located in the constellation Corona Borealis, is an X-ray luminous galaxy cluster. Its creation is due to the merger between two galaxy clusters. It is one of the largest objects in the universe and is six million light years across. It holds hundreds of galaxies and enough gas to make a thousand more. The pressure fronts in the system have been traced in detail and are relatively cool 50 million degree Celsius. The central region is embedded in large...
