New experiment could reveal make-up of the universe
The detectors will become part of the Advanced Gamma Tracking Array (AGATA) experiment, currently based in Italy, which aims to create a 'fingerprint' of the inside of the atomic nucleus to understand the structure of all matter in the Universe, including human beings and the stars. view more (2009-08-06)
Astronomers weigh neutrinos with the universe
Neutrinos, the lightest of the known elementary particles, weigh a billionth (one part in a thousand million) of a hydrogen atom at most, and can account for no more than one-fifth of the dark matter in the Universe, according to findings by astronomers in Cambridge, who used data from the Anglo-Australian telescope 2dF Galaxy Redshift Survey... view more...

Seeing the Invisible - Astronomers Pin Down Dark Matter Distribution
The mysterious invisible Dark Matter in the Universe is distributed just like galaxies on large scales, according to findings by scientists in Edinburgh, Rutgers/Princeton and Cambridge, using data from the Anglo-Australian telescope 2dF Galaxy Redshift Survey. What is more, there isn`t enough of it to cause the Universe to stop expanding. The... view more... (2001-12-10)
Galaxy evolution in cyber universe matches astronomical observations in fine detail
Scientists at the University of Chicago have bolstered the case for a popular scenario of the big bang theory that neatly explains the arrangement of galaxies throughout the universe. view more (2006-06-06)
Gresham College appoints Professor John Barrow to address the "Big Questions" of the Universe
Professor John Barrow, who has delivered lectures on cosmology at the Venice Film Festival, 10 Downing Street, Windsor Castle and the Vatican Palace, will begin a series of lectures on major developments in astronomy at Gresham College this autumn. Professor Barrow has been appointed by the Council of Gresham College as Gresham Professor of... view more... (2003-04-24)
Cannibalistic Stars hold clue to Big Bang
A team of UK astronomers announced this month the discovery of cannibalistic stars that explain one of the mysteries surrounding the Big Bang. The stars are almost as old as the Universe and they reveal what space was like in the very beginning. The team from the Open University found that a group of 14-billion-year-old stars were all in a spin... view more... (2002-05-10)
Physicists say universe evolution favored three and seven dimensions
Physicists who work with a concept called string theory envision our universe as an eerie place with at least nine spatial dimensions, six of them hidden from us, perhaps curled up in some way so they are undetectable. view more (2005-09-29)
The 2002 Nobel Prize in Physics
The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Physics for 2002 with one half jointly to Raymond Davis Jr Department of Physics and Astronomy, University of Pennsylvania, Philadelphia, USA, and Masatoshi Koshiba International Center for Elementary Particle Physics, University of Tokyo, Japan "for pioneering... view more...

University of Minnesota astronomers find gaping hole in the Universe
University of Minnesota 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, as well as the mysterious, unseen "dark matter." While earlier studies have shown holes, or voids, in the large-scale structure of the Universe, this new... view more... (2007-08-24)
Newly discovered galaxy cluster in early stage of formation is farthest ever identified
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. view more (2008-04-01)
First Black Holes Born Starving
The first black holes in the universe had dramatic effects on their surroundings despite the fact that they were small and grew very slowly, according to recent supercomputer simulations carried out by astrophysicists Marcelo Alvarez and Tom Abel of the Kavli Institute for Particle Astrophysics and Cosmology, jointly located at the Department of... view more...

Intense heat killed the Universe's would-be galaxies, researchers say
Our Milky Way galaxy only survived because it was already immersed in a large clump of dark matter which trapped gases inside it. view more (2009-07-01)
New recipe for dwarf galaxies: Start with leftover gas
There is more than one way to make a dwarf galaxy, and NASA's Galaxy Evolution Explorer has found a new recipe. view more (2009-02-19)
Hunting the Southern Skies with SIMBA
First Images from the New "Millimetre Camera" on SEST at La Silla A new instrument, SIMBA ("SEST IMaging Bolometer Array"), has been installed at the Swedish-ESO Submillimetre Telescope (SEST) at the ESO La Silla Observatory in July 2001. It records astronomical images at a wavelength of 1.2 mm and is able to quickly map large sky areas. In order... view more... (2001-08-30)
FSU physicist shining a light on mysterious 'dark matter'
We've all been taught that our bodies, the Earth, and in fact all matter in the universe is composed of tiny building blocks called atoms. Now imagine if this weren't the case. view more (2007-10-03)
Astronomers find triple interactions of supermassive black holes to be common in early universe
New cosmological computer simulations produced by a team of astronomers from Northwestern University, Harvard University and the University of Michigan show for the first time that supermassive black holes (SMBHs), which exist at the centers of nearly all galaxies, often come together during triple galaxy interactions. view more (2007-01-09)
The Tiny Difference that Created the Universe
Roughly 15 billion years ago, during the Big Bang, equal amounts of matter and anti-matter should have been created, with an anti-particle for every particle created. Yet when matter and anti-matter meet, they both disappear in a flash of light, so why didn't they annihilate each other completely? For some reason, during the first moments of the... view more...

Galaxy cluster smashes distance record
The most distant galaxy cluster yet has been discovered by combining data from NASA's Chandra X-ray Observatory and optical and infrared telescopes. view more (2009-10-23)
New understanding of the origin of galaxies advanced
A new theory as to how galaxies were formed in the Universe billions of years ago has been formulated by Hebrew University of Jerusalem cosmologists. The theory takes issue with the prevailing view on how the galaxies came to exist. view more (2009-01-22)
New population of faint protogalaxies discovered
Astronomers have found a new population of faint protogalaxies by taking the most sensitive spectroscopic survey ever of a time when the universe was only 15% of its present age. view more (2007-11-29)
