Gamma-ray bursts: are we safe?
For a few seconds every day, Earth is bombarded by gamma rays created by cataclysmic explosions in distant galaxies. Such explosions, similar to supernovae, are known as 'gamma-ray bursts' or GRBs. Astronomers using ESA's X-ray observatory, XMM-Newton, are trying to understand the cause of these... view more (2003-09-17)

Mystery of R Coronae Borealis and other helium stars solved
Astronomers Dr Simon Jeffery of the Armagh Observatory and Dr Hideyuki Saio of Tohoku University, Japan, have finally solved a long-standing mystery concerning the creation of two particular kinds of rare stars. They have found that a class of variable stars named after their prototype R Coronae... view more (2002-03-25)

Astronomers search for orphan stars using newly upgraded telescope

Planet finders use much faster instrument to discover distant planet
Astronomers have discovered a planet orbiting a very young star nearly 100 light years away using a relatively small, publicly accessible telescope turbocharged with a new planet-finding instrument.   view more (2006-01-12)

The Azov Sea: Radiation Recedes
Radioactive contamination of the Azov Sea has reached the level which existed before 1986 when the wreck of the Chernobyl nuclear power plant occurred. However, scientists state that regular check-ups of radio-ecological situation in the sea should be continued as the sea can be contaminated for... view more (2003-09-12)

Decades of accumulated change court ecosystem catastrophe
Subjected to decades of gradual change by humans, many of the world’s natural ecosystems – from coral reefs and tropical forests to northern lakes and forests – appear susceptible to sudden catastrophic ecological change, an international consortium of scientists reports Thursday... view more (2001-10-08)

Biodiversity controls ecological 'services,' report scientists in comprehenisive analysis
Accelerating rates of species extinction pose problems for humanity, according to a comprehensive study headed by a biologist at the University of California, Santa Barbara and published in the journal Nature this week.   view more (2006-10-26)

In Unique Stellar Laboratory, Einstein's Theory Passes Strict, New Test
Taking advantage of a unique cosmic configuration, astronomers have measured an effect predicted by Albert Einstein's theory of General Relativity in the extremely strong gravity of a pair of superdense neutron stars. Essentially, the famed physicist's 93-year-old theory passed yet another test.   view more (2008-07-07)

Species Diversity Less Dramatic Than Believed
A study published in the current issue of Science challenges the long-held belief that diversity of marine species has been increasing continuously since the origin of animals. Dr. Thomas D. Olszewski, a geology and geophysics professor at Texas A&M University, has been a part of the... view more (2008-07-08)

Observation of X-rays from birth of supernova leads to all-out effort to record stellar death
The lucky capture in January of an X-ray outburst from the very beginning of a supernova allowed astronomers around the world to quickly follow up with ground-based telescopes and collect a wealth of new information on early processes in stellar explosions, according to a paper newly submitted to... view more (2008-05-22)

Williams College faculty/student team travel to study solar eclipse
A team of Williams College faculty and students is preparing to scientifically observe the total eclipse of the Sun that will sweep across the far side of Earth on March 29.   view more (2006-03-21)

UK Astronomers to Build Unique Radio Telescope
UK astronomers are poised for a new era of discovery with the development of e-MERLIN, the world`s most powerful radio telescope. This ambitious project will use new technology to connect antennas across the UK, creating the largest and most sensitive linked network in the world. The 217km MERLIN... view more (2001-12-05)

Evidence for ultra-energetic particles in jet from black hole
An international team of astronomers led by researchers at Yale has obtained key infrared observations that reveal the nature of quasar particle jets that originate just outside super-massive black holes at the center of galaxies and radiate across the spectrum from radio to X-ray wavelengths.   view more (2006-06-21)

UK Provides Effective Access To Upcoming Solar Dynamics Observatory
Details of UK involvement in upcoming mission to study the Sun will be outlined at the RAS National Astronomy Meeting in Birmingham on Thursday 7th April. Dr Lidia van Driel-Gesztelyi of UCL's Mullard Space Science Laboratory will make a presentation on NASA's Solar Dynamic Observatory mission,... view more (2005-03-30)

Hydro-ecoregions, a natural framework for water management
The way in which a river functions depends on the nature of the terrain through which it flows, the relief, climate and human activity in the catchment. For this reason, there is wide environmental diversity in aquatic systems. Beneficial action in one place will not necessarily work elsewhere,... view more (2003-06-11)

Will The Leonids Go Out With A Bang?
Anyone willing to brave the early morning cold on 19 November may be rewarded with one of Nature's most spectacular firework displays - a major meteor storm. This year's Leonid meteor shower is expected to provide the last great storm for at least 30 years, and possibly the biggest in the 21st... view more (2002-11-15)

Environmental researchers propose radical 'human-centric' map of the world
Ecologists pay too much attention to increasingly rare "pristine" ecosystems while ignoring the overwhelming influence of humans on the environment, say researchers from McGill University and the University of Maryland, Baltimore County (UMBC).   view more (2007-11-27)

Astronomers detect echoes from ancient supernovae
A team of astronomers has found faint visible "echoes" of three ancient supernovae by detecting centuries-old light reflected by interstellar gas clouds hundreds of light-years removed from the original explosions.   view more (2005-12-22)

UK pupils scan the skies for hazardous asteroids
Tracking newly discovered asteroids and comets to identify their orbits is the work of a small number of observatories. Yet UK students, using the Faulkes Telescope North - a remotely operated research quality telescope dedicated for educational use - will now be swelling these ranks. The students... view more (2004-10-06)

Cows as unravellers
Long-term conservation of biodiversity may depend not only on the maintenance of its component parts but also on their interactions. Human-aided species introductions stand out as a major anthropogenic modification of ecological systems, and there is increasing concern that such introductions can... view more (2003-11-24)

TIMMI2 Images the Heart of the Orion Nebula
A new astronomical instrument, TIMMI2, has just been installed on the ESO 3.6-m telescope at La Silla.
