Winds of 320 000 kilometres per hour on the Sun
The SUMER instrument on the ESA-NASA SOHO spacecraft has measured amazing wind speeds during its observations of the Sun. It sets a new record in its examination of two loops of gas arching in the solar atmosphere, where NASA`s TRACE satellite spotted bright blobs of gas. Shifts in the wavelength of ultraviolet light from highly ionized neon... view more... (2002-05-17)
Extreme Winds Rule Exoplanet's Weather
Supersonic winds more than six times faster than those on Jupiter are blasting through the atmosphere of a Jupiter-sized planet 60 light years away, say scientists who've analyzed results from NASA's Spitzer Space Telescope. view more (2007-05-10)
Dust-enshrouded star looks similar to our sun
Astronomers report tremendous quantities of warm dusty debris surrounding a star with luminosity and mass similar to the sun's, but located 300 light-years from Earth. view more (2005-07-21)
New efficiency record for solar cells
The efficiency improvement is achieved by the use of an ultra-thin aluminum oxide layer at the front of the cell, and it brings a breakthrough in the use of solar energy a step closer. view more (2008-05-15)
Silicon nanoparticles enhance performance of solar cells
Placing a film of silicon nanoparticles onto a silicon solar cell can boost power, reduce heat and prolong the cell's life, researchers now report. view more (2007-08-21)
Evidence mounts for sun's companion star
he Binary Research Institute (BRI) has found that orbital characteristics of the recently discovered planetoid, "Sedna", demonstrate the possibility that our sun might be part of a binary star system. view more (2006-04-25)
Solar Contribution To 'Global Warming' Predicted To Decrease
New research on the sun's contribution to global warming is reported in this month's Astronomy & Geophysics. By looking at solar activity over the last 11,000 years, British Antarctic Survey (BAS) astrophysicist, Mark Clilverd, predicts that the sun's contribution to warming the Earth will reduce slightly over the next 100 years. This is a... view more... (2003-10-01)
Higher efficiency organic solar cell created by UCSB Nobel Laureate and research team
Using plastics to harvest the energy of the sun just got a significant boost in efficiency thanks to a discovery made at the Center for Polymers and Organic Solids at the University of California, Santa Barbara. view more (2007-07-13)
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)
Unique gathering of spacecraft yields new views, clues on Jupiter's magnetosphere
A space probe carrying British-designed and operated instruments has helped scientists to understand the magnetosphere surrounding Jupiter better than ever before. view more (2002-02-26)
Solar cycle linked to global climate, drives events similar to El Nino, La Nina
Establishing a key link between the solar cycle and global climate, new research led by the National Center for Atmospheric Research (NCAR) shows that maximum solar activity and its aftermath have impacts on Earth that resemble La Nina and El Nino events in the tropical Pacific Ocean. view more (2009-07-17)
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)
Cosmic Rays Hit Space Age High
Planning a trip to Mars? Take plenty of shielding. According to sensors on NASA's ACE (Advanced Composition Explorer) spacecraft, galactic cosmic rays have just hit a Space Age high. view more (2009-09-30)
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)
Glowing Accolade For Scottish Solar Physicist
A University of St Andrews solar physicist has been awarded one of the world's most prestigious accolades for his shining contribution to solar theory. Professor Eric Priest of the School of Mathematics and Statistics was this week awarded the Hale Prize 2002, usually awarded every two years by the American Astronomical Society (AAS). It is the... view more... (2002-06-07)
Mars 96: UK Involvement In The Russian Mission
The Particle Physics and Astronomy Research Council had awarded more than £1/2 million funding for work by UK scientists involved in several of the MARS 96 mission's payload and systems. The largest UK contribution was from the Mullard Space Science Laboratory, led by Principal Investigator Professor Alan Johnstone. Mullard designed and... view more... (1996-11-18)
Space technology keeps Nuna II ahead of the pack
The Nuon Solar Team look set to beat their own world record for driving a sun-powered car across Australia in the World Solar Challenge. At the end of day 3 Nuna II, despite two flat tires, finished half an hour ahead of its closest competitors. Nuna II, raced by the Nuon Solar Team, and aided by ESA space technology, reached Cadney Homestead,... view more... (2003-10-21)
New spaceship force field makes Mars trip possible
According to the international space agencies, "Space Weather" is the single greatest obstacle to deep space travel. Radiation from the sun and cosmic rays pose a deadly threat to astronauts in space. view more (2008-11-04)
Sunny times ahead for cheaper solar power
Greater use of clean electricity from the sun should be a step closer, thanks to new research carried out in the UK. The research has shown how the cost of generating solar electricity can be reduced, laying the foundation for a major expansion in the use of this sustainable energy technology. The project has been undertaken by a team of... view more... (2003-03-27)
Solar cycle linked to global climate
Establishing a key link between the solar cycle and global climate, research led by scientists at the National Science Foundation (NSF)-funded National Center for Atmospheric Research (NCAR) in Boulder, Colo., shows that maximum solar activity and its aftermath have impacts on Earth that resemble La Niña and El Niño events in the... view more...
