New evidence for dark energy in the universe
An international team of astronomers, led by scientists at the University of Manchester have produced new evidence that most of the energy in the Universe is in the form of the mysterious "Dark Energy". The new evidence comes from a 10-year census of the sky for examples of gravitational lenses,... view more (2002-11-09)

Dark energy -- 10 years on
Three quarters of our universe is made up of some weird, gravitationally repulsive substance that was only discovered ten years ago - dark energy.   view more (2007-11-30)

Supercomputer could throw light on 'mysterious' dark energy
Cosmologists have run a series of huge computer simulations of the Universe that could ultimately help solve the mystery of dark energy.   view more (2008-01-11)

Key mechanism for star formation found?
The team, led by Dan Clemens, from Boston University Institute for Astrophysical Research, examined a distant cloud of gas and dust called GF9, located about 1300 light years away. It shows a filamentary or wispy appearance, with dark "globules" distributed along its length. The new observation... view more (1999-06-03)

GAMMA RAYS AND DARK MATTER
For a long time it has been known that the Milky Way is surrounded by a (nearly spherical) halo of invisible matter, which contributes at least 90% of the whole galactic mass. Yet, almost nothing is known about the nature of such a dark halo.   view more (1999-02-26)

Texas A&M researchers examine Einstein's theories on the universe
Einstein's self-proclaimed "biggest blunder" - his postulation of a cosmological constant (a force that opposes gravity and keeps the universe from collapsing) - may not be such a blunder after all, according to the research of an international team of scientists that includes two Texas... view more (2007-11-28)

Astronomers discover largest-ever dark matter structures spanning 270M light-years
A University of British Columbia astronomer with an international team has discovered the largest structures of dark matter ever seen. Measuring 270 million light-years across, these dark matter structures criss-cross the night sky, each spanning an area that is eight times larger than the full... view more (2008-02-22)

Night blindness may explain fear of the dark
Fear of the dark is a common complaint in children and is often attributed to attention seeking behaviour. Yet researchers in this week's BMJ suggest that it may be due to night blindness - a diagnosis which can be easily missed. They describe two children with an inherited form of stationary night... view more (2003-01-22)

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... view more (2007-08-24)

Dark energy existed in infant universe
Using NASA's Hubble Space Telescope, researchers have discovered that dark energy, a mysterious repulsive force that makes the universe expand at an ever-faster rate, is not new but rather has been present in the universe for most of its 13-billion-year history.   view more (2006-11-17)

Rare galaxies shed light on a dark universe
Researchers based at the Institute for Computational Cosmology (ICC) in Durham and at Caltech in California, have found striking proof that their computer simulations of the universe can accurately predict how galaxies are clustered, so helping to reveal the distribution of dark matter throughout... view more (2002-04-04)

A few squares of dark chocolate a day may stave off artery hardening in smokers
Dark chocolate may stave off artery hardening in smokers, and a few squares every day could potentially cut the risk of serious heart disease.   view more (2005-12-20)

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)

Clash of clusters provides new dark matter clue
A powerful collision between galaxy clusters has been captured by the NASA/ESA Hubble Space Telescope and NASA's Chandra X-ray Observatory. This clash of clusters provides striking evidence for dark matter and insight into its properties.   view more (2008-08-28)

'Beyond Einstein' research should begin with mission to study dark energy
NASA and the U.S. Department of Energy should pursue the Joint Dark Energy Mission (JDEM) as the first mission in the "Beyond Einstein" program, according to a new report from the National Research Council.   view more (2007-09-07)

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... view more (2002-04-03)

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... view more (2002-04-04)

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... view more (2007-01-17)

Oldest stars may shed light on dark matter, researchers report in Science
The universe's earliest stars may hold clues to the nature of dark matter, the mysterious stuff that makes up most of the universe's matter but doesn't interact with light, cosmologists report.   view more (2007-09-14)

High Energy Mystery lurks at the Galactic Centre
A mystery lurking at the centre of our own Milky Way galaxy - an object radiating high-energy gamma rays - has been detected by an international team of astronomers. Their research, published today (September 22nd) in the Journal Astronomy and Astrophysics, was carried out using the High Energy... view more (2004-09-22)

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)

New technology sharpens X-ray vision
Researchers at the Paul Scherrer Institute (PSI) and the EPFL in Switzerland have developed a novel method for producing dark-field x-ray images at wavelengths used in typical medical and industrial imaging equipment.   view more (2008-01-21)

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)

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)

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.... view more (2005-03-16)
