ESA’s Cluster was in the right place and time to make a shocking discovery. The four spacecraft encountered a shock wave that kept breaking and reforming – predicted only in theory. picked by AutumnLotus 3 years ago

More than 100 nations have reached an agreement on a treaty which would ban current designs of cluster bombs.

"Current Designs"?? Doesn't that just defeat the object? picked by thenegativeone 2 years ago

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. These galaxies are so distant that the universe was in its infancy when their light was emitted. picked by AutumnLotus 2 years ago

A distant galaxy cluster has turned into a giant particle accelerator, spinning electrons over vast distances at high speeds. Scientists discovered this phenomenon by observing highly energetic X-rays emanating from the Ophiuchus cluster of galaxies. picked by AutumnLotus 2 years ago

Astronomers have glimpsed the largest cluster of galaxies ever seen in the distant, early universe. The discovery of this far-off group, estimated to contain as much mass as a thousand large galaxies, offers further proof of the existence of the enigmatic force called dark energy. picked by AutumnLotus 2 years ago

With the conventional theory of gravitation, based on Newton’s ideas and refined by Einstein 92 years ago, dark matter helps to explain the motion of galaxies, and clusters of galaxies, on the largest scales. Now two Canadian researchers suggest that the motion of galaxies in a distant cluster is more easily explained by a Modified Gravity (MOG) theory than by the presence of dark matter. picked by AutumnLotus 2 years ago

Oxygen is constantly leaking out of Earth’s atmosphere and into space. Now, ESA’s formation-flying quartet of satellites, Cluster, has discovered the physical mechanism that is driving the escape. It turns out that the Earth’s own magnetic field is accelerating the oxygen away. picked by AutumnLotus 2 years ago

A team of Virginia Commonwealth University scientists has discovered a ‘magnetic superatom’ – a stable cluster of atoms that can mimic different elements of the periodic table – that one day may be used to create molecular electronic devices for the next generation of faster computers with larger memory storage. picked by AutumnLotus 9 months ago

An unusual electrical disturbance has been spotted in space, travelling unchanged through the ionised gas surrounding Earth. A European space mission called Cluster detected a "soliton" wave, a phenomenon similar to the self-contained solitons that can travel along optical fibres and channels of water on Earth. This is the first known soliton in space. picked by AutumnLotus 2 years ago

"This is statistically unheard of," said Tallahassee resident Mike Partain, 41, a breast cancer survivor who was born at the base and is looking for others like himself. "We've got a cancer cluster that defies explanation." picked by TraumaMamma 5 months ago

The joint Japan-U.S. Suzaku mission is providing new insight into how assemblages of thousands of galaxies pull themselves together. For the first time, Suzaku has detected X-ray-emitting gas at a cluster's outskirts, where a billion-year plunge to the center begins. picked by AutumnLotus 10 months ago

Jülich scientists have made an important step on the long road to artificially imitating photosynthesis. They were able to synthesise a stable inorganic metal oxide cluster, which enables the fast and effective oxidation of water to oxygen. picked by AutumnLotus 2 years ago

The Hubble Space Telescope has captured a spectacular image of NGC 3603, a giant nebula hosting one of the most prominent massive young clusters in the Milky Way, thus supplying a prime template for star formation studies. picked by AutumnLotus 2 years ago

The orbiting X-ray telescopes XXM-Newton and Chandra have caught a pair of galaxy clusters merging into a giant cluster. The discovery adds to existing evidence that galaxy clusters can collide faster than previously thought. picked by AutumnLotus 3 years ago
