A Glimpse of the Very Early Universal Web
The VLT Maps Extremely Distant Galaxies New, trailblazing observations with the ESO Very Large Telescope (VLT) at Paranal lend strong support to current computer models of the early universe: It is "spongy", with galaxies forming along filaments, like droplets along the strands of a spiders web. A... view more (2001-05-18)

Unveiling the Secret of a Virgo Dwarf Galaxy
Dwarf galaxies may not be as impressive in appearance as their larger brethren, but they are at least as interestingfrom a scientific point of view. And sometimes they may have hidden properties that will only be found by means of careful observations, probing the signals of their stars at the... view more (2000-05-03)

Hubble's sweeping view of the Coma Galaxy Cluster
The NASA/ESA Hubble Space Telescope captures the magnificent starry population of the Coma Cluster of Galaxies, one of the densest known galaxy collections in the Universe.   view more (2008-06-10)

The dark matter of the universe has a long lifetime
New research from the Niels Bohr Institute presents new information that adds another piece of knowledge to the jigsaw puzzle of the dark mystery of the universe - dark matter. The research has just been published in the scientific journal Physical Review Letters.   view more (2007-10-02)

Sussex University astronomer takes part in NASA mission
When NASA launches its new orbiting observatory this week, a University of Sussex astronomer will be looking at parts of the universe never seen before. Dr Sebastian Oliver is one of just a handful of UK scientists involved in the largest project for NASA's Space Infrared Telescope Facility... view more (2003-08-20)

Stellar birth control in the early universe
An international team of astronomers based at Yale and Leiden University in The Netherlands found that "old stars" dominated many large galaxies in the early universe, raising the new question of why these galaxies progressed into "adulthood" so early in the life of the universe.   view more (2006-10-02)

Scientists solve cosmological puzzle
Researchers using supercomputer simulations have exposed a very violent and critical relationship between interstellar gas and dark matter when galaxies are born - one that has been largely ignored by the current model of how the universe evolved.   view more (2007-11-30)

Astronomers put quasars in their place
A team of UK astronomers, led by postgraduate student Ed Hawkins, has made a decisive step toward resolving an argument that has rumbled on in the astronomical community for decades. The scientists from the University of Nottingham have been investigating the properties of quasars and nearby... view more (2002-10-03)

Galaxies of stars shrouded in dust found in the early universe
A team of astronomers based in the UK and the US has for the first time measured the redshifts of a significant sample of puzzling "submillimetre galaxies", discovered by some members of the team in 1997. Dr Ian Smail of the University of Durham will tell the UK/Ireland National Astronomy Meeting... view more (2003-03-31)

Into the Epoch of Galaxy Formation
Current theories hypothesize that more than 80% of all stars ever formed were assembled in galaxies during the latter half of the elapsed lifetime of the Universe, i.e., during the past 7-8 billion years.   view more (2000-02-17)

Hubble sees the graceful dance of 2 interacting galaxies
A pair of galaxies, known collectively as Arp 87, is one of hundreds of interacting and merging galaxies known in our nearby Universe. Arp 87 was originally discovered and catalogued by astronomer Halton Arp in the 1970s. Arp's Atlas of Peculiar Galaxies is a compilation of astronomical photographs... view more (2007-10-31)

Hubble and Spitzer Space Telescopes find 'Lego-block' galaxies in early universe
The conventional model for galaxy evolution predicts that small galaxies in the early Universe evolved into the massive galaxies of today by coalescing. Nine Lego-like "building block" galaxies initially detected by Hubble likely contributed to the construction of the Universe as we know... view more (2007-09-07)

NASA'S Chandra finds black holes stirring up galaxies
Black holes are creating havoc in unsuspected places, according to a new study of images of elliptical galaxies made by NASA's Chandra X-ray Observatory.   view more (2006-01-11)

UK Astronomers look forward to looking back
When NASA launches its Space Infrared Telescope Facility (SIRTF) - the agency's fourth 'Great Observatory' - later this week, astronomers around the world will be looking forward to using one of the most powerful time machines ever built. Among those anticipating the opportunity to look back... view more (2003-08-19)

Music of the black holes: they all play the same tune
Astronomers at the University of Southampton have uncovered a remarkable connection between the monstrous black holes residing at the hearts of distant galaxies and their comparatively tiny cousins which inhabit star systems in our own Milky Way: they are playing the same tunes. Dr Phil Uttley... view more (2002-04-04)

Astronomers discover dozens of mini-galaxies
A new survey made with the Anglo-Australian Telescope (AAT) has revealed dozens of previously unsuspected miniature galaxies in the nearby Fornax galaxy cluster. They belong to a class of galaxies dubbed "ultra-compact dwarfs" (UCDs), which was unknown before the same team of astronomers... view more (2004-03-25)

'Cosmic telescopes' may have found infant galaxies
Using massive clusters of galaxies as "cosmic telescopes," a research team led by a Johns Hopkins University astronomer has found what may be infant galaxies born in the first billion years after the beginning of the universe.   view more (2006-06-06)

Dark matter mystery deepens in cosmic 'train wreck'
Astronomers have discovered a chaotic scene unlike any witnessed before in a cosmic "train wreck" between giant galaxy clusters.   view more (2007-08-17)

Radio Telescopes Reveal Unseen Galactic Cannibalism
Radio-telescope images have revealed previously-unseen galactic cannibalism -- a triggering event that leads to feeding frenzies by gigantic black holes at the cores of galaxies. Astronomers have long suspected that the extra-bright cores of spiral galaxies called Seyfert galaxies are powered by... view more (2008-06-24)

Compact galaxies in early Universe pack a big punch
Using the Near Infrared Camera and Multi-Object Spectrometer onboard of the Hubble NASA/ESA Hubble Space Telescope, astronomers have made observations of young, surprisingly compact galaxies, each only 5,000 light-years across, but weighing 200 billion times the mass of the Sun.   view more (2008-04-30)

Dwarf galaxies need dark matter too, U-M astronomers say
Stars in dwarf spheroidal galaxies behave in a way that suggests the galaxies are utterly dominated by dark matter, University of Michigan astronomers have found.   view more (2007-10-25)

Flies in a spider's web: Galaxy caught in the making
In nature spiders earn our respect by constructing fascinating, well-organised webs in all shapes and sizes. But the beauty masks a cruel, fatal trap. Analogously, the NASA/ESA Hubble Space Telescope has found a large galaxy 10.6 billion light-years away from Earth (at a redshift of 2.2) that is... view more (2006-10-12)

Spitzer nets thousands of galaxies in a giant cluster
In just a short amount of time, NASA's Spitzer Space Telescope has bagged more than a thousand previously unknown dwarf galaxies in a giant cluster of galaxies.   view more (2007-05-29)

Caltech astronomers describe the bar scene at the beginning of the universe
Bars abound in spiral galaxies today, but this was not always the case. A group of 16 astronomers, led by Kartik Sheth of NASA's Spitzer Science Center at the California Institute of Technology, has found that bars tripled in number over the past seven billion years, indicating that spiral galaxies... view more (2008-07-30)
