Hubble finds first organic molecule on extrasolar planet
The tell-tale signature of the molecule methane in the atmosphere of the Jupiter-sized extrasolar planet HD 189733b has been found with the Hubble Space Telescope. Under the right circumstances methane can play a key role in prebiotic chemistry - the chemical reactions considered necessary to form life as we know it. view more (2008-03-20)
Astronomers discover record 5th planet around nearby star 55 Cancri
A team of American astronomers announced today (Tuesday, Nov. 6) the discovery of a record-breaking fifth planet around the nearby star 55 Cancri, making it the only star aside from the sun known to have five planets. view more (2007-11-07)
Astronomers find first habitable Earth-like planet
Astronomers have discovered the most Earth-like planet outside our Solar System to date, an exoplanet with a radius only 50% larger than the Earth and capable of having liquid water. view more (2007-04-25)
The fine line between stability and instability -- when do gas giants reach the point of no return?
Planetary scientists at UCL have identified the point at which a star causes the atmosphere of an orbiting gas giant to become critically unstable, as reported in this week's Nature (December 6). view more (2007-12-06)
CU-Boulder space scientists set for second spacecraft flyby of Mercury
NASA's MESSENGER spacecraft, which is toting an $8.7 million University of Colorado at Boulder instrument to measure Mercury's wispy atmosphere and blistering surface, will make its second flyby of the mysterious, rocky planet Oct. 6. view more (2008-10-01)
'Over The Moon' At Saturn
UK scientists involved in the Cassini space mission were 'over the Moon' after the spacecraft's 100,000 km per hour white knuckle ride courtesy of Saturn's gravity which successfully completed the critical manoeuvre to place Cassini in orbit around the ringed planet. 'I've waited 15 years for this moment,' said Dr Andrew Coates of the UK's... view more... (2004-07-01)
Hunt for planets outside solar system uncovers a small one
Perhaps edging closer to finding planets that harbor life, astronomers have discovered the smallest planet yet identified outside our solar system. view more (2006-01-26)
Astronomers find stellar cradle where planets form
Astronomers at the University of Illinois have found the first clear evidence for a cradle in space where planets and moons form. view more (2007-11-30)
UCF, UCLA astronomers first to measure night and day on extrasolar planet
University of Central Florida Astronomy professor Joseph Harrington and University of California at Los Angeles professor Brad M. Hansen and their team have made the first direct observation of distinct day and night temperatures on a planet orbiting another star. view more (2006-10-13)
Exoplanets clue to sun's curious chemistry
"For almost 10 years we have tried to find out what distinguishes stars with planetary systems from their barren cousins," says Garik Israelian, lead author of a paper appearing this week in the journal Nature. "We have now found that the amount of lithium in Sun-like stars depends on whether or not they have planets." view more (2009-11-12)
Jupiter's massive winds likely generated from deep inside its interior, scientists report
A new computer model indicates Jupiter's massive winds are generated from deep within the giant planet's interior, a UCLA scientist and international colleagues report today in the journal Nature. view more (2005-11-14)
Surprisingly rapid changes in the Earth's core discovered
In a recent paper published in Nature Geoscience, the geophysicist Mioara MANDEA from the GFZ German Research Centre for Geosciences, Potsdam and her Danish colleague Nils OLSEN from the National Space Institute/DTU Copenhagen, have shown that motions in the fluid in the Earth's core are changing surprisingly fast, and that this, in turn, effects... view more...

Nitric oxide plays a vital role in the formation of long-term memory in snails
Snails can teach us a great deal about how we form memories, according to a group of neuroscientists at the University of Sussex. Research by Dr Ildik' Kemenes, Professor Paul Benjamin, Professor Michael O'Shea and colleagues shows that nitric oxide plays a vital role in the formation of long-term memory in snails. This is of crucial importance... view more... (2002-02-18)
Obtaining high performance coatings through simple latex film simulations
In the formation of high performance coatings, it is known that the process whereby a film forms from a colloidal dispersion is a key step. view more (2005-11-28)
Lightest exoplanet yet discovered
Well-known exoplanet researcher Michel Mayor today announced the discovery of the lightest exoplanet found so far. The planet, "e", in the famous system Gliese 581, is only about twice the mass of our Earth. view more (2009-04-22)
Scientists Recreate Martian Environment
Scientists at the University of Leicester's Space Research Centre are recreating the hostile environment found on Mars in their laboratory, with a device known as the Martian Environment Simulator (MES). The machine reproduces the temperature, air pressure and unbreathable atmosphere known to exist on Mars. The MES is currently being used to test... view more... (2002-05-31)
And now the weather ... on Mars
Blinding dust storms can seriously ruin your plans for a landing on Mars. ESA is adapting the global climate models that we use to forecast our weather on Earth for the turbulent conditions that Mars offers its future visitors. You could hardly call the weather on Mars pleasant, and presently it is far from predictable. As well as having an... view more... (2002-07-03)
Polarization technique focuses limelight
An international team of astronomers, led by Professor Svetlana Berdyugina of ETH Zurich's Institute of Astronomy, has for the first time ever been able to detect and monitor the visible light that is scattered in the atmosphere of an exoplanet. view more (2007-12-27)
NASA images, White Sands features support a wetter Mars
NASA's announcement yesterday of evidence that water still flows on Mars, at least in brief spurts, demonstrates that the view of Mars as a very dry planet should be reevaluated, says Dawn Sumner, professor of geology at UC Davis. Recent work from by Sumner and graduate student Greg Chavdarian also supports the presence of liquid water near the... view more... (2006-12-08)
Saturn's winds are variable
A team of astrophysicists at the University of the Basque Country has detected, for the first time ever, changes in Saturn's winds. The research has merited front page coverage in the scientific magazine, Nature. The winds blowing around Saturn and Jupiter are special. Unlike those of the rest of the planets, these move in an eastwards direction... view more... (2003-06-09)
