Gas giants jump into planet formation early
Observations from NASA's Spitzer Space Telescope show that gas giants either form within the first 10 million years of a sun-like star's life, or not at all. view more (2007-01-09)
Solar Power Game-Changer: "Near Perfect" Absorption of Sunlight, From All Angles
Researchers at Rensselaer Polytechnic Institute have discovered and demonstrated a new method for overcoming two major hurdles facing solar energy. view more (2008-11-04)
Half-baked asteroids have Earth-like crust
Asteroids are hunks of rock that orbit in the outer reaches of space, and scientists have generally assumed that their small size limited the types of rock that could form in their crusts. view more (2009-01-08)
Astronomers discover two new planets, both among the hottest ever
Astronomers have discovered two new planets outside our solar system, both extremely close to their stars and thus among the hottest ever found. view more (2006-09-27)
SMART-1 detects calcium on the Moon
Thanks to measurements by the D-CIXS X-ray spectrometer, ESA's SMART-1 spacecraft has made the first ever unambiguous remote-sensing detection of calcium on the Moon. view more (2005-06-08)
'Thin-layer' solar cells may bring cheaper 'green' power
Scientists are researching new ways of harnessing the sun's rays which could eventually make it cheaper for people to use solar energy to power their homes. view more (2007-08-24)
A bright future with solar lanterns for India's poor
Solar energy has the potential to improve the living conditions of poor rural households in India as well as contribute to the country's future energy security, according to Professor Govindasamy Agoramoorthy from Tajen University, who is Tata-Sadguru Visiting Chair, and Dr. Minna Hsu from the National Sun Yat-sen University in Taiwan. view more (2009-04-28)
New Planet Is Larger than Pluto
Claims that the Solar System has a tenth planet are bolstered by the finding by a group lead by Bonn astrophysicists that this alleged planet, announced last summer and tentatively named 2003 UB313, is bigger than Pluto. view more (2006-02-02)
New study: Why solar cells lose potency
Commercial products such as laptop computer monitors and solar-powered calculators are constructed from a light-sensitive material with a peculiar problem: When exposed to intense light, it forms defects, reducing the efficiency of the solar cells by 10 to 15 percent. view more (2005-06-20)
Titania nanoparticles could lead to improved sensors and solar energy
Nanostructured titania (TiO2) has been extensively studied as a very promising material for applications in sensors, photocatalysis, solar energy conversion and optical coatings. view more (2005-12-06)
Twin Keck Telescopes Probe Dual Dust Disks
Astronomers using the twin 10-meter telescopes at the W. M. Keck Observatory in Hawaii have explored one of the most compact dust disks ever resolved around another star. view more (2009-09-25)
Geoengineering could slow down the global water cycle
As fossil fuel emissions continue to climb, reducing the amount of sunlight hitting the Earth would definitely have a cooling effect on surface temperatures. view more (2008-05-28)
From Darwin to Adelaide, the length of Australia, 3010 kilometres, without fuel!
On 19 October 30 cars will be jostling for position at the start of the 7th World Solar Challenge in Darwin, Australia. After winning in 2001 with Nuna I, the Nuon Solar Team, from the Netherlands, will be bidding to retain their title. The strong team of twelve from Delft University of Technology and Erasmus University Rotterdam are determined... view more... (2003-10-17)
Primitive Visitor From Space Arrives In UK
Scientists from the Natural History Museum (NHM) in London, working with colleagues from the Open University (OU) in Milton Keynes, have been examining an intriguing arrival from outer space. The Tagish Lake meteorite, which fell in the Yukon region of northern Canada on the morning of 18 January 2000, contains some of the most primitive material... view more... (2001-03-31)
Unique Quantum Effect Found in Silicon Nanocrystals
Researchers at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL), collaborating with Innovalight, Inc., have shown that a new and important effect called Multiple Exciton Generation (MEG) occurs efficiently in silicon nanocrystals. MEG results in the formation of more than one electron per absorbed photon. view more (2007-07-26)
Good news: How the Earth will survive when the Sun becomes a supergiant
The astronomy textbooks will have to be rewritten, say astrophysicists at the University of Sussex who have re-examined standard calculations about solar evolution and the distant future of the Earth. The textbooks tell us that one day the Sun will burn up its nuclear fuel and expand to an enormous size, finally engulfing its inner planets... view more... (2002-01-08)
Sophisticated ESA space weather tool under development
If a satellite encounters high-energy particles or other 'space weather' phenomena before ground controllers can take action, on-board electronics could be disrupted, scientific instruments damaged and, in very rare and extreme cases, spacecraft may even be lost. view more (2007-02-05)
Sandia, Stirling Energy Systems set new world record for solar-to-grid conversion efficiency
On a perfect New Mexico winter day - with the sky almost 10 percent brighter than usual - Sandia National Laboratories and Stirling Energy Systems (SES) set a new solar-to-grid system conversion efficiency record by achieving a 31.25 percent net efficiency rate. view more (2008-02-14)
Scientists accurately simulate appearance of sun's corona during eclipse
The most true-to-life computer simulation ever made of our sun's multimillion-degree outer atmosphere, the corona, successfully predicted its actual appearance during the March 29, 2006, solar eclipse, scientists have announced. view more (2006-06-27)
Carbon nanotubes could make efficient solar cells
Using a carbon nanotube instead of traditional silicon, Cornell researchers have created the basic elements of a solar cell that hopefully will lead to much more efficient ways of converting light to electricity than now used in calculators and on rooftops. view more (2009-09-11)
