Mystery of missing hydrogen
Something vital is missing in the far distant reaches of the Universe: hydrogen - the raw material for stars, planets and possible life. view more (2008-11-24)
Italian, US cosmologists present alternate explanation for accelerating expansion of the universe: Was Einstein right when he said he was wrong?
Why is the universe expanding at an accelerating rate, spreading its contents over ever greater dimensions of space? An original solution to this puzzle, certainly the most fascinating question in modern cosmology, was put forward by four theoretical physicists, Edward W. Kolb of the U.S. Department of Energy's Fermi National Accelerator... view more... (2005-03-16)
Cosmic dance helps galaxies lose weight
A study published this week in the journal Nature offers an explanation for the origin of dwarf spheroidal galaxies. The research may settle an outstanding puzzle in understanding galaxy formation. view more (2009-07-30)
Tour takes Physics far and wide
A lecture "Particles and the Universe" aimed at the 16-19 age range, organised by the Institute of Physics, is being given in 40 venues in Britain during the current academic year, in what is the largest schools lecture tour ever staged by the IOP. The lecture is given by Professor Peter Kalmus of Queen Mary and Westfield College. In his talk,... view more... (1999-02-02)
Mapping the cosmic web of dark matter
What is Dark Matter and where is it found? These are two of the major mysteries in current studies of the Universe. Although the nature of this invisible material remains elusive, astronomers are beginning to produce detailed maps of the Cosmos, showing its location in relation to the ordinary matter that we can see in telescopes. One of the... view more... (2002-04-03)
Galaxies are born inside dark matter clumps, Cornell study of Spitzer Space Telescope data shows
Try mixing caramel into vanilla ice cream - you will always end up with globs and swirls of caramel. Scientists are finding that galaxies may distribute themselves in similar ways throughout the universe and in places where there is lots of so-called dark matter. view more (2006-04-20)
Blast from the past gives clues about early universe
Astronomers using the National Science Foundation's Very Large Array (VLA) radio telescope have gained tantalizing insights into the nature of the most distant object ever observed in the Universe -- a gigantic stellar explosion known as a Gamma Ray Burst (GRB). view more (2009-10-29)
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 (SIRTF), which leaves Cape Canaveral on Saturday, August... view more...

Dark energy may be vacuum
Researchers at the University of Copenhagen's Dark Cosmology Centre at the Niels Bohr Institute have brought us one step closer to understanding what the universe is made of. As part of the international collaboration ESSENCE they have observed distant supernovae (exploding stars), some of which emitted the light we now see more than half the age... view more...

Black Holes Lead Galaxy Growth, New Research Shows
Astronomers may have solved a cosmic chicken-and-egg problem -- the question of which formed first in the early Universe -- galaxies or the supermassive black holes seen at their cores. view more (2009-01-07)
ESA's XMM-Newton gains deep insights into the distant Universe
Using XMM-Newton, astronomers have obtained the world's deepest 'wide screen' X-ray image of the cosmos to date. Their observations show newly discovered clusters of galaxies and provide insights into the structure of the distant Universe"¦ Unlike grains of sand on a beach, matter is not uniformly spread throughout the Universe. Instead, it... view more... (2003-07-14)
Scientists weigh ingredients in recipe of the Universe
An international team of scientists from Cambridge, Manchester and Tenerife has released the first results of new high-precision observations of the relic radiation from the Big Bang, often called the cosmic microwave background or CMB. These observations have been made with a novel radio telescope called the Very Small Array (VSA) situated on... view more... (2002-05-23)
Cold Dust At The Heart Of TheUniverse
The Universe contains vast quantities of very cold dust and gas; from the relatively dense regions where young stars are born to the most distant galaxies, still in the process of forming after the Big Bang. The new SCUBA instrument, conceived, designed and built at the Royal Observatory, Edinburgh and installed on the James Clerk Maxwell... view more... (1996-06-28)
Cosmic dust in farthest quasar clue to early star formation
UK astronomers using the 15-m James Clerk Maxwell Telescope in Hawaii have discovered enormous quantities of cosmic dust in the most distant quasar yet observed. The quasar, called SDSS J1148+5251 is at a redshift (z) of 6.43, and is found in the direction of the constellation of Ursa Major. It is some 13 billion light years away, and we are... view more...

Fossil galaxy reveals clues to early universe
A tiny galaxy has given astronomers a glimpse of a time when the first bright objects in the universe formed, ending the dark ages that followed the birth of the universe. view more (2006-01-13)
Time reversal in the real world
If time went backwards life would look like a video recording played in reverse - or would it? New findings demonstrate that this common assumption may not hold true. Experiments showing for the first time that time is not symmetrical are explained today by Dr John Fry from the University of Liverpool at the British Association Festival of... view more...

In the first second of Creation
At the very beginning of the Universe both forms of matter existed in equal amounts. They should have cancelled themselves out leaving just energy. But, within a second, something happened to ensure that matter prevailed - and that the Universe could develop in the way that it did. BaBar should shed light on that critical event 15 billion years... view more... (1999-06-11)
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 billions of years to an era when the universe was in its... view more... (2003-08-19)
Big Bang theory saved
An apparent discrepancy in the Big Bang theory of the universe's evolution has been reconciled by astrophysicists examining the movement of gases in stars. view more (2006-10-27)
