A $2-billion experiment on the International Space Station has released the first data from its unprecedented census of the charged subatomic particles whizzing by Earth. Although the results largely confirm [...]

POWER HAS ITS PRIVILEGES AND Robert Williams knew exactly how he wanted to use his. As director of the Space Telescope Science Institute, which runs the Hubble Space Telescope, Williams [...]

In the next few weeks, the world's most sensitive dark matter detector will begin its operations under Italy's Gran Sasso mountain. This seems a good time to point out that [...]

ON July 4, 2012, a panel of scientists at the Large Hadron Collider in Geneva announced the discovery of a new particle, the long-anticipated Higgs boson (or something very much [...]

Astronomers working with the Hubble Space Telescop failed to find evidence of the dark matter that has been postulated as the key to the possible end of the universe. The researchers also found fewer red dwarf stars than expected in a survey of the Milky Way.

One of the biggest projects at the LHC is figuring out why particles have mass. Scientists think that a 'Higgs field' fills space, and the more strongly a particle interacts [...]

A sensitive experiment in Italy has found no sign of dark matter in 100 days of searching for the invisible material that is believed to account for over 80 percent [...]

Science is like espionage. Agents from competing powers attempt to wrest secrets from nature's grasp. It may be for a noble cause, but just as with real-life spies, there's a [...]

HUMAN KNOWLEDGE OF THE COSMOS increased dramatically in the 20th century as large ground-based telescopes and orbiting observatories such as Hubble allowed us to see far beyond our galaxy. In [...]

Dwarf galaxies may not look like much, but don't be fooled. They offer the purest pools of dark matter available anywhere. The smaller a galaxy, the larger its proportion of [...]

A quest to redefine the nature of the universe is underway in a mine shaft in Soudan, Minn., where physicists with the Cryogenic Dark Matter Search have been looking since [...]

Cosmologists are agog about the possibility that an orbiting observatory may have discovered particles of dark matter--the invisible material that researchers believe makes up most of the mass of the [...]

PARANAL MOUNTAIN, Chile--British astronomers have shone a small light on one of the biggest mysteries of the universe--the identity of dark matter. The ordinary matter we can see and touch [...]

After measuring the relatively slow motions of planetary nebulae in several elliptical galaxies, a team led by Aaron J. Romanowsky (now at the University of Concepcion, Chile) reported in 2003 [...]

About half the heat in the Earth's core comes from natural radioactive processes, according to measurements taken at a special facility buried under a mountain in central Japan. Over the [...]

Huge amounts of invisible matter spread these multiple images wide. ASTRONOMY IS a record-breaking science. When a very wide gravitationally lensed quasar was announced in late 2003, breaking the separation [...]

A former salt mine in north Yorkshire is the somewhat unlikely setting for the search for one of astronomy's last great mysteries--dark matter. Scientists can only explain the behaviour of [...]
