Benchmark Survey Shows that Giant Outer Extrasolar Planets Are Rare
Astronomers who used powerful telescopes in Arizona and Chile in a survey for planets around nearby stars have discovered that extrasolar planets more massive than Jupiter are extremely rare in other outer solar systems. view more (2007-07-12)
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)
Study highlights role of hit-and-run collisions in planet formation
Hit-and-run collisions between embryonic planets during a critical period in the early history of the Solar System may account for some previously unexplained properties of planets, asteroids, and meteorites. view more (2006-01-12)
Scorched Earth millenium map shows 'fire scars'
A geographer from the University of Leicester has produced for the first time a map of the scorched Earth for every year since the turn of the Millennium. view more (2008-05-23)
Where are the other `Earths` beyond the Solar System?
One of the most fascinating areas of astronomical research in recent years has been the search for other `Earths` circling Sun-like stars far beyond our Solar System. In recent years nearly 100 planets have been discovered in orbits around other stars, but none of these `exoplanets` remotely resembles the Earth. However, according to the latest... view more...

Glaciers Reveal Martian Climate Has Been Recently Active
The prevailing thinking is that Mars is a planet whose active climate has been confined to the distant past. About 3.5 billion years ago, the Red Planet had extensive flowing water and then fell quiet - deadly quiet. It didn't seem the climate had changed much since. view more (2008-04-24)
Research suggests we may be genetically programmed to care about the long-term future
Humans may be programmed by evolution to care about the future of the environment, suggests research published today. view more (2009-05-28)
NASA predicts nongreen plants on other planets
NASA scientists believe they have found a way to predict the color of plants on planets in other solar systems. view more (2007-04-11)
Complex meteorology at Venus
In its relentless probing of Venus's atmosphere, ESA's Venus Express keeps revealing new details of the Venusian cloud system. Meteorology at Venus is a complex matter, scientists say. view more (2006-10-16)
Rebecca boldly goes from star-gazing to space research
A Kingston University graduate is about to set off on an academic mission to discover if there is life on other planets. Earth and planetary science specialist Rebecca Blackhurst hopes to land a research job at America's National Aeronautics and Space Administration (NASA) at the end of her trek through the academic world. First she intends to... view more... (2003-06-27)
Planet Orbiting a Giant Red Star Discovered with Hobby-Eberly Telescope
A planet orbiting a giant red star has been discovered by an astronomy team led by Penn State's Alex Wolszczan, who in 1992 discovered the first planets ever found outside our solar system. view more (2007-08-03)
COROT space mission ready to search out new planets and map the interior of stars
The COROT mission is scheduled for launch on the 27th December 2006, from Baikonur in Kazakhstan. view more (2006-12-21)
The Radar Search For Martian Water
Until the last few years, Mars has been regarded as a cold, arid world that lost most of its water long ago. However, recent observations by NASA's Mars Global Surveyor and Mars Odyssey spacecraft have provided tantalising evidence that huge amounts of water may be hidden just below the surface. Now, a powerful new instrument is poised to probe... view more... (2003-04-01)
MIT, Harvard offer solution to Mars enigma
Planetary scientists have puzzled for years over an apparent contradiction on Mars. Abundant evidence points to an early warm, wet climate on the red planet, but there's no sign of the widespread carbonate rocks, such as limestone, that should have formed in such a climate. view more (2007-12-26)
Simulation suggests rocky exoplanet has bizarre atmosphere
So accustomed are we to the sunshine, rain, fog and snow of our home planet that we find it next to impossible to imagine a different atmosphere and other forms of precipitation. view more (2009-10-01)
NASA Supercomputer Shows How Dust Rings Point to Exo-Earths
Supercomputer simulations of dusty disks around sunlike stars show that planets nearly as small as Mars can create patterns that future telescopes may be able to detect. The research points to a new avenue in the search for habitable planets. view more (2008-10-13)
Mars, methane and mysteries
Mars may not be as dormant as scientists once thought. The 2004 discovery of methane means that either there is life on Mars, or that volcanic activity continues to generate heat below the martian surface. view more (2009-08-10)
Moon and Four Planets in the Evening Sky - a Prelude to the Venus Transit
During the coming evenings, everybody under clear skies will be able to enjoy a beautiful view in the twilight. Right after sunset, planet Venus is visible as a brilliant point of light above the western horizon - and two other planets, Mars and Saturn, are seen to the left of Venus as somewhat less bright objects. More to the south and higher in... view more... (2004-04-21)
Gullies on Mars show tantalizing signs of recent water activity
Planetary geologists at Brown University have found a gully fan system on Mars that formed about 1.25 million years ago. The fan offers compelling evidence that it was formed by melt water that originated in nearby snow and ice deposits and may stand as the most recent period when water flowed on the planet. view more (2009-03-02)
Flawless launch of a super Meteosat
Almost 25 years after the November 1977 launch of the very first Meteosat, the first representative of the next generation (MSG-1) of European weather satellites has been placed in orbit and is being made ready to lend new dimensions to the monitoring of our planet`s climate. On 28 August at 1945h local time (2245h GMT), a European Ariane-5... view more... (2002-08-29)
