UK astronomers have developed the most sensitive infrared map of the distant universe ever produced, revealing the origins of the most massive galaxies in the cosmos. Using images obtained with the United Kingdom Infra-Red Telescope (UKIRT), astronomers combined data over a period of three years. This produced a map encompassing more than 100,000 galaxies over an area of sky four times the size of the full moon. picked by AutumnLotus 4 months ago tags old galaxies stick young universe infrared map |

A team of astronomers looking at the universe’s distant past found nine young, unusually compact galaxies, each weighing in at 200 billion times the mass of the Sun. 0 comments edit related share scienceThese young galaxies are the equivalent of a human baby that is 20 inches long, yet weighs 180 pounds. picked by AutumnLotus 4 months ago |

Dusty infrared galaxies are cosmic "nurseries" for some of the universe's hottest young stars -- and new research from NASA's Spitzer Space Telescope shows that when the universe was approximately six billion years old, these galaxies packed into the densest "zip codes" in space. Astronomers hope that this latest finding will give them insights into why the modern universe look... read full post picked by AutumnLotus 10 months ago 1 comments edit related share plime.com |

Preliminary results from the volunteers indicate that the universe possesses the property called “handedness.” That is, most galaxies seem to be left-handed, or prefer to rotate counterclockwise when looked at from our position on the planet Earth. picked by AutumnLotus 9 months ago 1 comments edit related share plime.com |

Recently, two groups of astronomers were able to see two classes of unique galaxies from the early universe. One group glimpsed galaxies that looked old even when the universe was young, suggesting they must have been some of the first galaxies to form after the birth of the universe. The other group found galaxies dating from the strongest burst of star formation in the universe. picked by AutumnLotus 5 months ago 0 comments edit related share science |

Astronomers have used ESO’s Very Large Telescope to measure the distribution and motions of thousands of galaxies in the distant Universe. This opens fascinating perspectives to better understand what drives the acceleration of the cosmic expansion and sheds new light on the mysterious dark energy that is thought to permeate the Universe. picked by AutumnLotus 7 months ago 0 comments edit related share science |

Astronomers using the NASA/ESA Hubble Space Telescope have compiled a large catalogue of gravitational lenses in the distant Universe. The catalogue contains a staggering 67 new gravitationally lensed images found around massive elliptical and lenticular-shaped galaxies. picked by AutumnLotus 6 months ago 0 comments edit related share science |

Astronomers are using the NASA/ESA Hubble Space Telescope to dissect one of the largest structures in the Universe as part of a quest to understand the violent lives of galaxies. Hubble is providing indirect evidence of unseen dark matter tugging on galaxies in the crowded, rough-and-tumble environment of a massive supercluster of hundreds of galaxies. picked by AutumnLotus 7 months ago 0 comments edit related share science |

Huge filaments of dark matter have been detected in a survey of thousands of distant galaxies. The discovery supports the idea that dark matter drove the formation of galaxies and larger cosmic structures and resolves a discrepancy in previous studies about how much dark matter the universe contains. picked by AutumnLotus 6 months ago 0 comments edit related share science |

Using ESO's Very Large Telescope, an international team of astronomers has discovered a stunning rare case of a triple merger of galaxies. This system, which astronomers have dubbed 'The Bird' - albeit it also bears resemblance with a cosmic Tinker Bell - is composed of two massive spiral galaxies and a third irregular galaxy. picked by AutumnLotus 7 months ago 1 comments edit related share science |

An image based on data taken with ESO's Very Large Telescope reveals a triplet of galaxies intertwined in a cosmic dance. The three galaxies, catalogued as NGC 7173 (top), 7174 (bottom right) and 7176 (bottom left), are located 106 million light-years away towards the constellation of Piscis Austrinus (the 'Southern Fish'). picked by AutumnLotus 7 months ago 0 comments edit related share science |

Astronomers from SRON Netherlands Institute for Space Research have discovered a new cluster of galaxies, hidden behind a previously identified cluster of galaxies. The recently exposed cosmic giant is apparently just as bright as the first group, but is six times further away. The astronomers made the discovery as part of an international team using the space telescope XMM-Newton. picked by AutumnLotus 8 months ago 1 comments edit related share plime.com |

Hundreds of "missing" black holes have been found lurking in dusty galaxies billions of light-years away. The finding is the first direct evidence that most, if not all, massive galaxies in the distant universe spent their youths constructing supermassive black holes at their cores. picked by AutumnLotus 10 months ago 6 comments edit related share plime.com |

Astronomers have found an enormous hole in the Universe, nearly a billion light-years across, empty of both normal matter such as stars, galaxies, and gas, and the mysterious, unseen "dark matter." While earlier studies have shown holes, or voids, in the large-scale structure of the Universe, this new discovery dwarfs them all. picked by AutumnLotus 12 months ago 3 comments edit related share plime.com |

Stars always evolve in the universe in large groups, known as clusters. Astronomers distinguish these formations by their age and size. The question of how star clusters are created from interstellar gas clouds and why they then develop in different ways has now been answered by researchers at the Argelander Institute for Astronomy at the University of Bonn with the aid of computer simulations. picked by AutumnLotus 10 months ago 0 comments edit related share plime.com |

When it comes to giving birth, galaxies don't seem to have a "ticking biological clock." In fact, observations from NASA's Spitzer Space Telescope show that old galaxies were the biggest producers of new stars when our universe was half of its current age of 13.6 billion years. picked by AutumnLotus 4 months 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 7 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 5 months ago 0 comments edit related share science |

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 7 months ago 0 comments edit related share science |
