Chance encounter with comet nets surprising results
Comets are made of the most primitive stuff in the solar system. As hunks of rock and ice that never coalesced into more planets, they give researchers clues to the evolution of solar systems. view more (2007-10-02)
Researchers think pink to produce 'green' solar energy
When it comes to producing earth-friendly solar energy, pink may be the new green, according to Ohio State University researchers. Scientists here have developed new dye-sensitized solar cells, that get their pink color from a mixture of red dye and white metal oxide powder in materials that capture light. view more (2007-07-31)
Search for the water of life -- UCL astronomers find water on extra-solar planet
Researchers at UCL (University College London) are part of an international team which has discovered water on an extra-solar planet for the first time. view more (2007-07-12)
Sunquakes Reveal The Solar Furnace
Most people are familiar with the fact that sensitive instruments known as seismographs can detect earthquakes taking place many hundreds or thousands of miles away. By studying the waves from these tremors, scientists can find out about the conditions deep inside our rocky planet. In the same way, astronomers are now able to measure millions... view more...

ESA studies the Sun-Earth climate link
Meteorologists can no longer view the Earth as an isolated system. Both long-term climate changes and day-to-day weather show links with the Sun`s activity. Scientists therefore study the nature of those links intensely. With data from ESA`s spaceprobes SOHO, Cluster, and Ulysses, we now have the information we need to solve the mystery of how the... view more... (2002-08-23)
Earth's magnetic field could help protect astronauts working on the moon
It has been 35 years since humans last walked on the moon, but there has been much recent discussion about returning, either for exploration or to stage a mission to Mars. However, there are concerns about potential radiation danger for astronauts during long missions on the lunar surface. view more (2007-12-11)
NASA Scientists Closer to Timely Space Weather Forecasts
Scientists funded by NASA have made big strides in learning how to forecast "all clear" periods, when severe space weather is unlikely. The forecasts are important because radiation from particles from the sun associated with large solar flares can be hazardous to unprotected astronauts, airplane occupants and satellites. view more (2005-08-18)
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)
Quantum dot recipe may lead to cheaper solar panels
Rice University scientists today revealed a breakthrough method for producing molecular specks of semiconductors called quantum dots, a discovery that could clear the way for better, cheaper solar energy panels. view more (2007-05-03)
Supernova radioisotopes show sun was born in star cluster, scientists say
The death of a massive nearby star billions of years ago offers evidence the sun was born in a star cluster, say astronomers at the University of Illinois at Urbana-Champaign. view more (2006-10-05)
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)
Computer simulation predicts Voyager 2 will reach major milestone in space in late 2007-early 2008
Using a computer model simulation, Haruichi Washimi, a physicist at UC Riverside, has predicted when the interplanetary spacecraft Voyager 2 will cross the "termination shock," the spherical shell around the solar system that marks where the solar wind slows down to subsonic speed. view more (2007-11-28)
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)
Solar-B
Solar flares are tremendous explosions on the surface of our Sun, releasing as much energy as a billion megatons of TNT in the form of radiation, high energy particles and magnetic fields. view more (2006-09-12)
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)
Nanopillars Promise Cheap, Efficient, Flexible Solar Cells
Researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory and the University of California at Berkeley have demonstrated a way to fabricate efficient solar cells from low-cost and flexible materials. view more (2009-07-10)
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)
Solar-B - a new solar mission to study the dynamic Sun
A new Japanese-led solar mission with ESA participation is preparing for launch on 23 September 2006. Solar-B will study the mechanisms which power the solar atmosphere and look for the causes of violent solar eruptions. view more (2006-09-21)
Comet from coldest spot in solar system has material from hottest places
Scientists analyzing recent samples of comet dust have discovered minerals that formed near the sun or other stars. That means materials from the innermost part of the solar system could have traveled to the outer reaches, where comets formed. view more (2006-03-14)
It's our solar system Jim, but not as we know it
There are many more objects orbiting our sun than we once thought, and a new book from Cambridge University Press sets out to tell the story of their discovery. Beyond Pluto: Exploring the Outer Limits of the Solar System by John Davies traces the history of the search for objects at the periphery of the solar system. It is a tale of incredible... view more... (2001-07-25)
