Trees to offset the carbon footprint?
How effective are new trees in offsetting the carbon footprint? A new study suggests that the location of the new trees is an important factor when considering such carbon offset projects. Planting and preserving forests in the tropics is more likely to slow down global warming. view more (2007-04-10)
New technique could find water on Earth-like planets orbiting distant suns
Since the early 1990s astronomers have discovered more than 300 planets orbiting stars other than our sun, nearly all of them gas giants like Jupiter. view more (2009-05-26)
Volcanic Activity Shaped Mercury After All
Scientists have long anguished over how little is known about Mercury, the innermost of the four terrestrial planetary bodies in our solar system. view more (2008-07-07)
Astonomers find tiny planet orbiting tiny star
An international team of astronomers led by David Bennett of the University of Notre Dame has discovered an extra-solar planet of about three Earth masses orbiting a star with a mass so low that its core may not be large enough to maintain nuclear reactions. The result was presented Monday (June 2) at the American Astronomical Society annual... view more... (2008-06-03)
Physicists create millimeter-sized 'Bohr atom'
Nearly a century after Danish physicist Niels Bohr offered his planet-like model of the hydrogen atom, a Rice University-led team of physicists has created giant, millimeter-sized atoms that resemble it more closely than any other experimental realization yet achieved. view more (2008-07-01)
APL Astronomer Spies Conditions 'Just Right' for Building an Earth
An Earth-like planet is likely forming 424 light-years away in a star system called HD 113766, say astronomers using NASA's Spitzer Space Telescope. view more (2007-10-04)
Wales hosts world workshop for better conservation
These special scientists, known as taxonomists are members of BioNET International, the brainchild of Professor Tecwyn Jones of Cardiff University. They are skilled in the science concerned with identifying, classifying and understanding the relationships of the myriad species of organisms which form the Earth's biodiversity. view more (1999-08-16)
Magnetic Tornadoes Could Liberate Mercury's Tenuous Atmosphere
As the closest planet to the sun, Mercury is scorching hot, with daytime temperatures of more than 800 degrees Fahrenheit (approximately 450 degrees Celsius). view more (2009-06-03)
Geoscience converges under pressure
The contents of the deep Earth affect the planet as a whole, including life at its surface, but scientists must find unusual ways to "see" it. view more (2007-05-22)
Astronomers discover most Earth-like extrasolar planet yet
The world's preeminent planet hunters have discovered the most Earth-like extrasolar planet yet: a possibly rocky world about 7.5 times as massive as the Earth. view more (2005-06-14)
Where did Venus's water go?
Venus Express has made the first detection of an atmospheric loss process on Venus's day-side. Last year, the spacecraft revealed that most of the lost atmosphere escapes from the night-side. view more (2008-12-19)
Even 'failed stars' form planets
An international team of astronomers shows that even brown dwarfs start to form planets. view more (2005-10-26)
How long is a day on Saturn?
Measuring the rotation period of a rocky planet like the Earth is easy, but similar measurements for planets made of gas, such as Saturn, pose problems. view more (2006-05-04)
Key molecule discovered in Venus's atmosphere
Venus Express has detected the molecule hydroxyl on another planet for the first time. This detection gives scientists an important new tool to unlock the workings of Venus's dense atmosphere. view more (2008-05-16)
Arizona State scientists keep an eye on Martian dust storm
Scientists at Arizona State University's Mars Space Flight Center are using the Thermal Emission Imaging System (THEMIS) on NASA's Mars Odyssey orbiter to monitor a large dust storm on the Red Planet. view more (2007-07-12)
MIT finds young planets stay hotter longer
Hot, young planets may be easier to spot because they stay that way longer than astronomers have thought, according to new work by MIT planetary scientist Linda Elkins-Tanton. view more (2008-10-16)
Mars Express confirms methane in the Martian atmosphere
During recent observations from the ESA Mars Express spacecraft in orbit around Mars, methane was detected in its atmosphere. Whilst it is too early to draw any conclusions on its origin, exciting as they may be, scientists are thinking about the next steps to take in order to understand more. From the time of its arrival at Mars, the Mars... view more... (2004-03-30)
Mystery of fossilized trees is solved
An international research team has found evidence of the Earth's earliest forest trees, dating back 385 million years. view more (2007-04-19)
Mars Express: no signal from Beagle 2 so far
ESA's Mars Express orbiter made its first attempt to establish contact with the Beagle 2 lander, after the two spacecraft separated on 19 December 2003. The orbiter made its first pass over the Beagle 2 landing site today at 13:13 CET, but could not pick up any signal from the tiny lander. More attempts to contact Beagle 2 are planned in the... view more... (2004-01-07)
Geologists finding a different Mars underneath
Scientists are finding an older, craggier face of Mars buried beneath the surface, thanks to pioneering sounding radar co-sponsored by NASA aboard the European Space Agency's Mars Express spacecraft. view more (2006-12-14)
