WASHINGTON, Aug. 18, 2011 /PRNewswire-USNewswire/ -- NASA spacecraft observations and new data processing techniques are giving scientists better insight into the evolution and development of solar storms that can damage satellites, disrupt communications and cause power grid failures on Earth. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) The solar storms, called Coronal Mass Ejections (CMEs), are being observed from NASA's twin Solar Terrestrial Relations Observatory,...

Those who study the sun face an unavoidable hurdle in their research "“ their observations must be done from afar. Relying on images and data collected from 90 million miles away, however, makes it tough to measure the invisible magnetic fields sweeping around the sun. Scientists must learn more about these fields because they are crucial to understanding how coronal mass ejections, or CMEs, travel through space -- sometimes toward Earth where they can damage satellites. Now NASA...

ESA's Proba-2 small Sun-watcher was among the flotilla of satellites on watch as the Sun erupted spectacularly this week. After years of relative quietness, the Sun is waking up. Tuesday 7 June saw a medium-class M2.5 solar flare, associated with a proton storm, a coronal mass ejection that glanced past Earth on Thursday 9 June and an accompanying burst of radio energy. ESA's Proba-2 satellite was launched in November 2009, during the most inactive period of the solar cycle, but now the Sun...

A NASA space observatory witnessed an unusual solar flare on Tuesday that could cause interference to satellites, communications and power on Earth in the next few days, officials warn. Not since 2006 has an eruption of this magnitude been seen reports the National Weather Service. A statement by NASA's solar dynamics observatory says, "The sun unleashed an M-2 (medium-sized) solar flare with a substantial coronal mass ejection (CME) on June 7 that is visually spectacular." "The large cloud...

So great is the wealth of data about the Sun now being sent back by space missions such as SOHO, STEREO and the Solar Dynamics Observatory (SDO) that scientists back on Earth can struggle to keep pace. To combat this data overload, scientists from the Visual Computer Centre at Bradford University are developing advanced imaging tools to help scientists visualize what's happening at the Sun, make sense of the data and predict the extreme solar activities that could affect our life here on...

The largest disturbances to the Earth's geomagnetic environment occur when it is buffeted by solar material hurled in our direction by explosive changes in the Sun's atmosphere. These Coronal Mass Ejections or CMEs contain approximately a billion tons of ionized gas or plasma and can have a dramatic and damaging impact on everything from satellites to power grids. Now a team of scientists have used two spacecraft to study these events in unprecedented detail. Graduate student Anthony Williams...

Researchers today provided the first computer model explaining the recent period of decreased solar activity during the Sun's 11-year cycle. This recent solar minimum was the deepest observed in about 100 years. The solar minimum has repercussions on the safety of space travel and the amount of orbital debris our planet accumulates. NASA said that scientists around the world were puzzled by the extended disappearances of sunspots in 2008 through 2009. "Plasma currents deep inside the sun...

Observers say that the Sun has unleashed its strongest flare in four years. The eruption was an X-flare, which is the strongest type of flare that can affect communications on Earth. NASA's Solar Dynamics Observatory (SDO) spacecraft recorded an intense flash of extreme ultraviolet radiation emanating from a sunspot. The British Geological Survey (BGS) issued a geomagnetic storm warning and said that observers might be able to see auroras from the northern U.K. The flare was recorded on...

Dr. Tony Phillips, NASA's Heliophysics News Team On Feb. 6th, NASA's twin STEREO probes moved into position on opposite sides of the sun, and they are now beaming back uninterrupted images of the entire star"”front and back. "For the first time ever, we can watch solar activity in its full 3-dimensional glory," says Angelos Vourlidas, a member of the STEREO science team at the Naval Research Lab in Washington, DC. "This is a big moment in solar physics," says Vourlidas. "STEREO has...

Solar and Heliospheric Observatory (SOHO) -- The SOHO (Solar & Heliospheric Observatory) project is being carried out by the European Space Agency (ESA) and the US National Aeronautics and Space Administration (NASA) as a cooperative effort between the two agencies in the framework of the Solar Terrestrial Science Program (STSP) comprising SOHO and CLUSTER, and the International Solar-Terrestrial Physics Program (ISTP), with Geotail (ISAS-Japan), Wind, and Polar. SOHO was launched on...

National Solar Observatory -- The National Solar Observatory (NSO) has its primary headquarters in Tucson. NSO telescopes on Kitt Peak include the McMath-Pierce Solar Telescope Facility containing the world's three largest solar telescopes (1.6-meter main and two 0.9-meter auxiliaries), along with the Vacuum Telescope and the Razdow small solar patrol telescope. The National Solar Observatory also operates telescopes at Sacramento Peak, New Mexico, that include the Vacuum Tower...
