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)
Texas A&M prof to predict weather on Mars
Is there such a thing as "weather" on Mars? There are some doubts, considering the planet's atmosphere is only 1 percent as dense as that of the Earth. view more (2009-11-05)
Giant Impact Near India -- Not Mexico -- May Have Doomed Dinosaurs
A mysterious basin off the coast of India could be the largest, multi-ringed impact crater the world has ever seen. And if a new study is right, it may have been responsible for killing the dinosaurs off 65 million years ago. view more (2009-10-16)
How the Moon produces its own water
The Moon is a big sponge that absorbs electrically charged particles given out by the Sun. These particles interact with the oxygen present in some dust grains on the lunar surface, producing water. view more (2009-10-15)
A Thermometer for the Earth
According to climate change experts, our planet has a fever - melting glaciers are just one stark sign of the radical changes we can expect. view more (2009-10-02)
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)
CU-Boulder space scientists set for final spacecraft flyby of Mercury
NASA's MESSENGER spacecraft, which is toting an $8.7 million University of Colorado at Boulder instrument, will make its third and final flyby of Mercury on Sept. 29 -- a clever gravity-assist maneuver that will steer it into orbit around the rocky planet beginning in March 2011. view more (2009-09-29)
Sea level stargazing: Astronomers make key sighting with Fla. telescope
This summer, University of Florida astronomers inaugurated the world's largest optical telescope on a nearly 8,000-foot mountaintop 3,480 miles away. view more (2009-09-29)
The greenhouse gas that saved the world
When Planet Earth was just cooling down from its fiery creation, the sun was faint and young. So faint that it should not have been able to keep the oceans of earth from freezing. But fortunately for the creation of life, water was kept liquid on our young planet. view more (2009-08-18)
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)
Jupiter pummeled, leaving bruise the size of the Pacific Ocean
Something slammed into Jupiter in the last few days, creating a dark bruise about the size of the Pacific Ocean. view more (2009-07-22)
Geoengineering: The promise and its limits
Four expert speakers attended an event organised by the Institute of Physics, the Royal Society of Chemistry and the Royal Academy of Engineering on 15 July, at the House of Commons, to address an audience curious about geo-engineering the planet to combat the effects of global warming; the solutions it offers and the concerns it raises. view more (2009-07-21)
Primitive asteroids in the main asteroid belt may have formed far from the sun
Many of the objects found today in the asteroid belt located between the orbits of Mars and Jupiter may have formed in the outermost reaches of the solar system. view more (2009-07-16)
New map hints at Venus's wet, volcanic past
Venus Express has charted the first map of Venus's southern hemisphere at infrared wavelengths. The new map hints that our neighbouring world may once have been more Earth-like, with both, a plate tectonics system and an ocean of water. view more (2009-07-14)
Galileo's notebooks may reveal secrets of new planet
Galileo knew he had discovered a new planet in 1613, 234 years before its official discovery date, according to a new theory by a University of Melbourne physicist. view more (2009-07-09)
Explosive growth of life on Earth fueled by early greening of planet
Earth's 4.5-billion-year history is filled with several turning points when temperatures changed dramatically, asteroids bombarded the planet and life forms came and disappeared. view more (2009-07-09)
University of Hawaii at Manoa astronomers discover pair of solar systems in the making
Two University of Hawai'i at Mānoa astronomers have found a binary star-disk system in which each star is surrounded by the kind of dust disk that is frequently the precursor of a planetary system. view more (2009-07-01)
ASU instrument takes better look at Mars minerals
A slow drift in the orbit of NASA's Mars Odyssey spacecraft that mission controllers started nine months ago is now giving an ASU instrument on the spacecraft a better and more sensitive view of minerals on the surface of Mars. view more (2009-06-23)
Caltech scientists predict greater longevity for planets with life
Roughly a billion years from now, the ever-increasing radiation from the sun will have heated Earth into inhabitability; the carbon dioxide in the atmosphere that serves as food for plant life will disappear, pulled out by the weathering of rocks; the oceans will evaporate; and all living things will disappear. view more (2009-06-15)
New definition could further limit habitable zones around distant suns
As astronomers gaze toward nearby planetary systems in search of life, they are focusing their attention on each system's habitable zone, where heat radiated from the star is just right to keep a planet's water in liquid form. view more (2009-06-11)
