How Old is the Universe?
Most astronomers would agree that the age of the Universe - the time elapsed since the "Big Bang" - is one of the "holy grails of cosmology". Despite great efforts during recent years, the various estimates of this basic number have resulted in rather diverse values. When derived from current cosmological models, it depends on a number of... view more... (2001-02-06)

What if there is only 1 universe?
Lee Smolin, author of the bestselling science book The Trouble with Physics and a founding member and research physicist at the Perimeter Institute for Theoretical Physics in Waterloo, Canada, writes exclusively in the June issue of Physics World explaining why theories of cosmology that suggest that our universe is just one of many - the... view more...

Scientists use world's fastest supercomputer to model origins of the unseen universe
Understanding dark energy is the number one issue in explaining the universe, according to Salman Habib, of the Laboratory's Nuclear and Particle Physics, Astrophysics and Cosmology group. view more (2009-10-27)
New space telescope aims to seek out and record explosive gamma ray bursts.
A state of the art space telescope built by scientists at UCL will make its way to the Goddard Space Flight Centre in Maryland, USA on a mission to unravel the mysteries of the universes gamma rays. The telescope - called UVOT - will be one of three telescopes on a special NASA orbiting space observatory planned for launch in 2003. The observatory... view more... (2002-05-31)
After the Big Bang: Project Explores Seconds that Shaped the Universe
Kent State faculty and graduate students are among a team of physicists who recreated the material essence of the universe as it would have been mere microseconds after the Big Bang—a quark-gluon plasma. view more (2006-07-13)
Throwing light on the dark side of the Universe
Although we may believe humans know a lot about the Universe, there are still a lot of phenomena to be explained. A team of cosmologists from the University of the Basque Country are searching for the model that best explains the evolution of the Universe. view more (2008-10-22)
Early universe was liquid
Experiments at the worlds largest nuclear collider, RHIC, at Brookhaven National Laboratory in New York, USA reveal striking new features of the state of the early Universe. A large Danish research group is part of this endeavor with professor Jens J'¸rgen Gaardh'¸je as a member of the top leadership of the experiments. view more (2005-04-19)
Is the Universe older than expected?
An analysis of 13.5 thousand million-year-old X-rays, captured by ESA's XMM-Newton satellite, has shown that either the Universe may be older than astronomers had thought or that mysterious, undiscovered 'iron factories' litter the early Universe. ESA`s Norbert Schartel and colleagues from the Max-Planck-Institut für extraterrestrische... view more... (2002-07-10)
Largest ever survey of very distant galaxy clusters completed
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. view more (2009-07-01)
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)
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...

Astronomers discover stars in early galaxies had a need for speed
A team of astronomers has measured the motions of stars in a very distant galaxy for the first time and discovered they are whizzing around at astonishingly high speeds-about one million miles per hour, or twice the speed at which the Sun circles our own Milky Way galaxy. view more (2009-08-07)
Cornell-led team detects dust around a primitive star, shedding new light on universe's origins
A Cornell-led team of astronomers has observed dust forming around a dying star in a nearby galaxy, giving a glimpse into the early universe and enlivening a debate about the origins of all cosmic dust. view more (2009-01-16)
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)
Cosmologists predict a static universe in 3 trillion years
When Dutch astronomer Willem de Sitter proposed a static model of the universe in the early 1900s, he was some 3 trillion years ahead of his time. view more (2007-05-24)
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)
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)
