IIA Developing Payload For ISRO's Solar Mission Aditya Tiruchirappalli, India (PTI) Jul 02, 2009 
The Bangalore-based Indian Institute of Astrophysics was developing a payload for Indian Space Research Organisation's proposed solar mission Aditya to study the Sun's outermost region corona, a scientist of the institute said on Monday. The payload would be included in Aditya, a mini satellite, being developed by ISRO to study emissions taking place in the Sun during solar maxim ... read moreScientists bid adieu to plucky solar probe 
Washington (AFP) June 30, 2009US and European scientists were Tuesday bidding farewell to the tenacious solar probe Ulysses which has been recording data around the sun for more than 18 years, four times longer than planned. "Ulysses has taught us more than we ever expected about the sun and the way it interacts with the space surrounding it," said Richard Marsden, Ulysses project manager with the European Space Agency ... more

Ulysses Mission Coming To An End
Paris, France (ESA) Jun 29, 2009Upon receipt of the last command from Earth, the transmitter on Ulysses will switch off on 30 June, bringing one of the most successful and longest missions in spaceflight history to an end. After 18.6 years in space and defying several earlier expectations of its demise, the joint ESA/NASA solar orbiter Ulysses will achieve 'end of mission' on 30 June 2009. The final communication ... more Sunspots Revealed In Striking Detail By Supercomputers 
Boulder CO (SPX) Jun 22, 2009In a breakthrough that will help scientists unlock mysteries of the Sun and its impacts on Earth, an international team of scientists led by the National Center for Atmospheric Research (NCAR) has created the first-ever comprehensive computer model of sunspots. The resulting visuals capture both scientific detail and remarkable beauty. The high-resolution simulations of sunspot pairs open ... more Sonograms Of The Sun Explain Mystery Of The Missing Sunspots 
Boulder CO (SPX) Jun 18, 2009Scientists from the National Solar Observatory (NSO) in Tucson, Arizona, have discovered that a solar jet stream deep inside the Sun is migrating slower than usual through the star's interior, giving rise to the current lack of sunspots and low solar activity, according to work being presented this week at the meeting of the Solar Physics Division of the American Astronomical Society (AAS/SPD). ... more Astronomy Question Of The Week - Does The Sun Have A Surface 
Bonn, Germany (SPX) Jun 17, 2009"Of course," we might answer, "what a question!" However, we should also consider that our Sun - like all other stars - is a ball of hot gas. This gas ball, with a diameter of 1.4 million kilometres, is held together by gravity alone. This means that the Sun does not have a firm surface. Nevertheless, the Sun appears to us as a shining sphere with a sharp edge. The reason for this is that ... more |

World's Largest Telescope Captures Sun's Magnetic Field Better
Newark NJ (SPX) May 25, 2009NJIT's new 1.6-meter clear aperture solar telescope-the largest of its kind in the world-is now operational. The unveiling of this remarkable instrument-said to be the pathfinder for all future, large ground-based telescopes-could not have come at a more auspicious moment for science. This year marks the 400th anniversary of Galileo's telescope that he used to demonstrate that sunspots are ... more Northrop Grumman Awarded Contract To Build CERES Sensor 
Redondo Beach CA (SPX) May 22, 2009Northrop Grumman was awarded a contract by NASA Langley Research Center to build a sensor that measures the time and space distributions of incoming energy from the sun and outgoing thermal and reflected energy from Earth (known as Earth's radiation budget). The sensor will be integrated onto the first National Polar-orbiting Operational Environmental Satellite System (NPOESS) spacecraft. ... more NOAA Predicts Mild Solar Storm Season 
Washington DC (SPX) May 11, 2009Although its peak is still four years away, a new active period of Earth-threatening solar storms will be the weakest since 1928, predicts an international panel of experts led by NOAA's Space Weather Prediction Center and funded by NASA. Despite the prediction, Earth is still vulnerable to a severe solar storm. Solar storms are eruptions of energy and matter that escape from the sun and ... more Watching Solar Activity Muddle Earth's Magnetic Field 
Paris, France (ESA) May 05, 2009Scientists have found that extreme solar activity drastically compresses the magnetosphere and modifies the composition of ions in near-Earth space. They are now looking to model how these changes affect orbiting satellites, including the GPS system. The results were obtained from coordinated in-situ measurements performed by ESA's four Cluster satellites along with the two Chinese/ESA Dou ... more |
