An international team of researchers led by a UC Riverside astronomer has completed the largest ever survey designed to find very distant clusters of galaxies. Named the Spitzer Adaptation of the Red-sequence Cluster Survey, "SpARCS" detects galaxy clusters using deep ground-based optical observations from the CTIO 4m and CFHT 3.6m telescopes, combined with Spitzer Space Telescope infrared observations. picked by AutumnLotus 5 months ago tags largest survey distant galaxy clusters completed |

Galaxies tend to give birth to their stars on the road, while travelling down intergalactic highways towards cosmic cities called galaxy clusters, new Spitzer Space Telescope observations reveal. Galaxies in relatively empty regions of the universe flock towards densely populated galaxy clusters, attracted there by the clusters' gravity. picked by AutumnLotus 2 years ago 0 comments edit related share science |
First results from the GOODS NICMOS survey, the largest Hubble Space Telescope program ever led from outside of the United States, reveal how the most massive galaxies in the early Universe assembled to form the most massive objects in the Universe today. picked by AutumnLotus 7 months ago 0 comments edit related share science |
This new guide for astronomers, known as the APEX Telescope Large Area Survey of the Galaxy (ATLASGAL) shows the Milky Way in submillimetre-wavelength light (between infrared light and radio waves). Images of the cosmos at these wavelengths are vital for studying the birthplaces of new stars and the structure of the crowded galactic core. picked by AutumnLotus 5 months ago 0 comments edit related share science |
UC Irvine scientists have discovered a cluster of galaxies in a very early stage of formation that is 11.4 billion light years from Earth – the farthest of its kind ever to be detected. These galaxies are so distant that the universe was in its infancy when their light was emitted. picked by AutumnLotus 2 years ago 0 comments edit related share science |
Astronomers have glimpsed the largest cluster of galaxies ever seen in the distant, early universe. The discovery of this far-off group, estimated to contain as much mass as a thousand large galaxies, offers further proof of the existence of the enigmatic force called dark energy. picked by AutumnLotus 1 year ago 1 comments edit related share science |

With the conventional theory of gravitation, based on Newton’s ideas and refined by Einstein 92 years ago, dark matter helps to explain the motion of galaxies, and clusters of galaxies, on the largest scales. Now two Canadian researchers suggest that the motion of galaxies in a distant cluster is more easily explained by a Modified Gravity (MOG) theory than by the presence of dark matter. picked by AutumnLotus 2 years ago 0 comments edit related share plime.com |
Anyone who has wondered what it might be like to dive into a pool of millions of distant galaxies of different shapes and colours, will enjoy the latest image released by ESO. Obtained in part with the Very Large Telescope, the image is the deepest ground-based U-band image of the Universe ever obtained. It contains more than 27 million pixels and is the result of 55 hours of observations with the... read full post picked by AutumnLotus 1 year ago 0 comments edit related share science |
Through some of the very first scientific observations with the brand-new Large Binocular Telescope (LBT) in Arizona, astronomers has found that a recently discovered tiny companion galaxy to our Milky Way, named the Hercules Dwarf Galaxy, has truly exceptional properties: while basically all of its known peers in the realm of these tiny dwarf galaxies are rather round, this galaxy at a distance o... read full post picked by AutumnLotus 2 years ago 2 comments edit related share plime.com |
More than 800,000 snapshots from NASA's Spitzer Space Telescope have been stitched together to create a new "coming of age" portrait of stars in our inner Milky Way galaxy. The image depicts an area of sky 120 degrees wide by two degrees tall. High-res zoomable image. picked by AutumnLotus 1 year ago 0 comments edit related share science |
Millions of clustered stars glisten like an iridescent opal in a new image from NASA's Spitzer Space Telescope. Called Omega Centauri, this sparkling orb of stars is like a miniature galaxy. It is the biggest and brightest of the more than 150 similar objects, called globular clusters, that orbit around the outside of our Milky Way galaxy. picked by AutumnLotus 2 years ago 0 comments edit related share science |

Galaxies today are struggling to clump together against the incredible repulsive power of dark energy, hints a new survey of thousands of galaxies. Measuring this anti-clumping effect puts a new arrow in the quiver of cosmologists seeking to uncover the nature of the mysterious force. picked by deepchill 2 years ago 0 comments edit related share science |
The galaxy, as large as the Milky Way, is about 12.8 billion light-years away and harbors a supermassive black hole that contains at least a billion times as much matter as our sun. The universe is about 13.7 billion years old, and faraway objects like this are seen as they existed near the dawn of time, their light just now arriving at Earth. picked by kakana 3 months ago 1 comments edit related share science |
Two galaxy clusters collided with each other. The image gathered from visible light as well as the way that gravity effected the light provides striking evidence for dark matter and insight into its properties.

The Hubble Space Telescope has found a large galaxy 10.6 billion light-years away from Earth that is stuffing itself with smaller galaxies caught like flies in a web of gravity. The galaxy is so far away that astronomers are seeing it as it looked in the early formative years of the Universe, only 2 billion years after the Big Bang. picked by 2manyusernames 3 years ago 2 comments edit related share science |
Newborn stars shine like celestial sparklers in a new portrait of the nearby Triangulum Galaxy – the most detailed ultraviolet image of a galaxy ever taken. Astronomers will use the image, taken by NASA's Swift telescope, to create an "age map" of the galaxy's components to understand how galaxies evolve over time. picked by AutumnLotus 2 years ago 2 comments edit related share science |
A furious rate of star formation discovered in a distant galaxy shows that galaxies in the early universe developed either much faster or in a different way from what astronomers have thought. The galaxy is forming the equivalent of 4,000 Suns a year. This is a thousand times more violent than our own Milky Way galaxy. picked by AutumnLotus 2 years ago 0 comments edit related share plime.com |
An international team of astronomers with the Trans-atlantic Exoplanet Survey announce today the discovery of TrES-4, a new extrasolar planet in the constellation of Hercules. The new planet was identified by astronomers looking for transiting planets – that is, planets that pass in front of their home star – using a network of small automated telescopes. picked by AutumnLotus 2 years ago 0 comments edit related share plime.com |
A distant galaxy cluster has turned into a giant particle accelerator, spinning electrons over vast distances at high speeds. Scientists discovered this phenomenon by observing highly energetic X-rays emanating from the Ophiuchus cluster of galaxies. picked by AutumnLotus 2 years ago 0 comments edit related share science |
The orbiting X-ray telescopes XXM-Newton and Chandra have caught a pair of galaxy clusters merging into a giant cluster. The discovery adds to existing evidence that galaxy clusters can collide faster than previously thought. picked by AutumnLotus 2 years ago 0 comments edit related share plime.com |
