Monster Of A Galaxy Cluster - El Gordo Lives Up To Its Nickname
2014-04-04 07:03:29

April Flowers for redOrbit.com - Your Universe Online | Source Material Provided by NASA El Gordo is Spanish for "the fat one," and the nickname of the largest galaxy known galaxy cluster in the distant universe, ACT-CLJ0102-4915. A new study from NASA's Hubble Space Telescope reveals that the galaxy cluster, which is 9.7 billion light-years from Earth, definitely lives up to its nickname. According to a NASA report, a team of astronomers measured how much the cluster's gravity warps...

Frontier Fields Project Locates One Of The Most Distant Galaxies Ever

[ Watch the Video: Abell2744 Y1 Is The Most Distant Galaxy Discovered ] redOrbit Staff & Wire Reports – Your Universe Online 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, existing at a time when the universe was no more than approximately 650 million years old. The galaxy, which is known as Abell2744 Y1, is roughly 30 times smaller than...

redOrbit Staff & Wire Reports - Your Universe Online 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. Abell 2744, which was first observed by the Hubble Space Telescope in 2011, is also known as Pandora’s Cluster because the mixture of elliptical and colorful spiral galaxies that formed...

WASHINGTON, Jan. 7, 2014 /PRNewswire-USNewswire/ -- NASA's Hubble Space Telescope is providing a new perspective on the remote universe, including new views of young and distant galaxies bursting with stars. Scientists described the findings Tuesday in a news conference sponsored by the American Astronomical Society (AAS). (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) Highlighted in the briefing were three discoveries -- four unusually bright galaxies as they...

Astronomers Use Gravitational Lensing To Weigh Most Distant Galaxy
2013-10-17 14:57:54

Lee Rannals for redOrbit.com - Your Universe Online Using a gravitational lensing technique, astronomers were able to weigh one of the most distant galaxies in the universe. Gravitational lensing is a technique used by astronomers that was first predicted by Albert Einstein's theory of relativity. As light from a very distant object moves through the universe, it can essentially be intensified by another object that is closer to Earth, reviving the light and making it possible for...

Dark Matter Evidence From Galaxy Cluster Abell 1689

[ Watch the Video: Pan Across Galaxy Cluster Abell 1689 ] redOrbit Staff & Wire Reports - Your Universe Online 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. In a study published earlier this week in the online edition of The Astrophysical Journal, Karla Alamo-Martinez of the Center for Radio Astronomy and Astrophysics of the National Autonomous...

WASHINGTON, Nov. 15, 2012 /PRNewswire-USNewswire/ -- By combining the power of NASA's Hubble and Spitzer space telescopes and one of nature's own natural "zoom lenses" in space, astronomers have set a new record for finding the most distant galaxy seen in the universe. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) The farthest galaxy appears as a diminutive blob that is only a tiny fraction of the size of our Milky Way galaxy. But it offers a peek back into a time when the...

Hubble Zooms In On Magnified Galaxy
2012-02-03 04:56:53

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. This observation provides a unique opportunity to study the physical properties of a galaxy vigorously forming stars when the universe was only one-third its present age. A so-called gravitational lens is produced when space is warped by a massive foreground object, whether it is the sun, a black hole or an entire...

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. But new data from a team of scientists from Liverpool John Moores University directly challenges this idea, suggesting that the growth of some of the most massive objects stopped 7 billion years ago when the Universe was half its present age. On Monday 18 April team member Claire Burke will present their work at the...

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. Dark matter is an invisible and unknown substance that makes up the bulk of the universe's mass. The new dark matter observations may yield new insights into the role of dark energy in the universe's early formative years. The result suggests that galaxy clusters may have formed earlier than expected, before the...

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...
