IBEX discovers that galactic magnetic fields may control the boundaries of our solar system
The first all-sky maps developed by NASA's Interstellar Boundary Explorer (IBEX) spacecraft, the initial mission to examine the global interactions occurring at the edge of the solar system, suggest that the galactic magnetic fields had a far greater impact on Earth's history than previously conceived, and the future of our planet and others may... view more...

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)
NASA Calls on APL to Send a Probe to the Sun
The Johns Hopkins University Applied Physics Laboratory is sending a spacecraft closer to the sun than any probe has ever gone - and what it finds could revolutionize what we know about our star and the solar wind that influences everything in our solar system. view more (2008-05-05)
Recycling wind turbines
The development of wind power promises much in terms of providing us with renewable energy for the future and wind turbines could be the most effective way to harness that power. view more (2007-09-21)
SECCHI team obtains images of the solar wind at Earth
Using the Sun Earth Connection Coronal and Heliospheric Investigation (SECCHI) instruments on board NASA's Solar Terrestrial Relations Observatory (STEREO) spacecraft, a consortium of scientists has seen, for the first time, large waves of solar material sweeping past Earth. view more (2007-12-10)
NASA spacecraft ready to explore outer solar system
The first NASA spacecraft to image and map the dynamic interactions taking place where the hot solar wind slams into the cold expanse of space is ready for launch Oct. 19. The two-year mission will begin from the Kwajalein Atoll, a part of the Marshall Islands in the Pacific Ocean. view more (2008-10-07)
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)
More economical and easier to install wind generator: the wind reservoir
Two Basque companies, Enerlim and NECESA, have developed a new wind generator, a wind reservoir to make use of wind energy. This wind reservoir is much lighter than ordinary three-arm wind generators; hence, it is more economical and easier to install. On the other side, the machine is completely modular, as columns, pulleys and plates can be... view more... (2002-03-25)
Researchers Identify Driver for Near-Earth Space Weather
New findings indicate that the aurora and other near-Earth space weather are driven by the rate at which the Earth's and Sun's magnetic fields connect, or merge, and not by the solar wind's electric field as was previously assumed. view more (2006-12-12)
International Dawn Chorus Day - Sunday 2nd May 2004
As nature lovers all over the world wake up to enjoy the enthusiastic sounds of birdsongs on International Dawn Chorus Day on 2 May, scientists at British Antarctic Survey's (BAS) Halley Research Station will listen to a very different Dawn Chorus. Each morning, as the Earth and its enveloping atmosphere turn towards the Sun, very low frequency... view more... (2004-04-29)
Getting into hot water
An analysis of the engineering and economics for a solar water-heating system shows it to have a payback period of just two years, according to researchers in India. They report, in the International Journal of Global Energy Issues, on the success of the 1000-liter system operating at a university hostel. view more (2009-03-09)
Inderscience Publishers
A way to make wind power smoother and more efficient that exploits the inertia of a wind turbine rotor could help solve the problem of wind speed variation, according to research published in the International Journal of Power Electronics. view more (2009-01-08)
Shifting the world to 100 percent clean, renewable energy as early as 2030 -- here are the numbers
Most of the technology needed to shift the world from fossil fuel to clean, renewable energy already exists. Implementing that technology requires overcoming obstacles in planning and politics, but doing so could result in a 30 percent decrease in global power demand. view more (2009-10-20)
ESA's Cluster solved an auroral puzzle
ESA's four Cluster spacecraft have made a remarkable set of observations that has led to a breakthrough in understanding the origin of a peculiar and puzzling type of aurora. These aurorae - seen as bright spots in Earth's atmosphere and called 'dayside proton auroral spots' - occur when fractures appear in the Earth's magnetic field, allowing... view more... (2003-05-20)
Stable power supply thanks to wind turbines
Wind turbines can help keep the voltage in the electricity network at a constant level. The power electronics in the turbines can effectively correct peaks and dips in the mains voltage. This is the conclusion reached by NWO-funded researchers. Modern wind turbines are a good means of coping with fluctuations in the mains voltage. Such... view more... (2001-10-08)
Solar wind tans young asteroids
A new study published in Nature this week reveals that asteroid surfaces age and redden much faster than previously thought -- in less than a million years, the blink of an eye for an asteroid. This study has finally confirmed that the solar wind is the most likely cause of very rapid space weathering in asteroids. This fundamental result will... view more... (2009-04-23)
Jupiter`s Electric Aurora
The planet Jupiter has spectacular rings of auroras around each pole but until now scientists have not been able to explain how they form. All auroras are caused by energetic charged particles crashing into the top of the atmosphere and making it glow. In the Earth's auroras, these particles come from the Sun in a flow of charged particles known... view more... (2002-03-26)
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)
