Observations from NASA's Solar Dynamics Observatory (SDO) and the Japanese satellite Hinode show that some gas in the giant, fountain-like jets in the sun's atmosphere known as spicules can reach temperatures of millions of degrees. The finding offers a possible new framework for how the sun's high atmosphere gets so much hotter than the surface of the sun. What makes the high atmosphere, or corona, so hot "“ over a million degrees, compared to the sun surface's 10,000 degrees...

During a total eclipse of the Sun, skywatchers are awed by the shimmering corona -- a faint glow that surrounds the Sun like gossamer flower petals. This outer layer of the Sun's atmosphere is, paradoxically, hotter than the Sun's surface, but so tenuous that its light is overwhelmed by the much brighter solar disk. The corona becomes visible only when the Sun is blocked, which happens for just a few minutes during an eclipse. Now, an instrument on board NASA's Solar Dynamics Observatory...

PALO ALTO, Calif., Dec. 13, 2010 /PRNewswire/ -- A serendipitous alignment of high-powered spaceborne solar instruments-designed and built by Lockheed Martin (NYSE: LMT)-has finally provided the data allowing scientists to uncover the physical mechanism behind so-called "sympathetic flares" on the Sun. For over 75 years, solar physicists have been observing near-synchronous explosions in the solar atmosphere, and have wondered whether they were somehow related, but hard evidence for...

On December 2, 1995, the Solar and Heliospheric Observatory or SOHO was launched into space from Cape Canaveral aboard an Atlas IIAS rocket. The joint ESA/NASA project began its work observing the sun at a time when the term "solar weather" was almost never used. Fifteen years later, SOHO has revolutionized what we know about the solar atmosphere and violent solar storms produced by the sun. SOHO has become an expert comet-hunter, nightly news leader and a workhorse that helped create the...

For almost 15 years, the EIT camera on board SOHO transmitted a picture of the solar corona every 12 minutes, providing ground-breaking observations of the Sun that changed our perception and understanding of our star. After a remarkable career, this instrument has now eased into semi-retirement. Although no longer as active as during its heyday, EIT will still provide snapshots of the Sun - at a more leisurely pace. Launched in late 1995 and still in operation, the SOHO mission has...

The sun is the largest and most important object in our solar system, containing 99.8% of the solar system's mass, or quantity of matter. Among that remaining 0.2% are hot planets, icy moons, asteroid belts, chunks of rock, rings of ice, and over 100 worlds -- including our Earth. The "space" in between is a mesmerizing mix of the push-and-pull of gravity, solar winds, particle radiation, and magnetospheres. Not bad for a mere 0.2%! On Thursday, July 1, scientist Jonathan Cirtain from NASA's...

Earth and space are about to come into contact in a way that's new to human history. To make preparations, authorities in Washington DC are holding a meeting: The Space Weather Enterprise Forum at the National Press Club on June 8th. Richard Fisher, head of NASA's Heliophysics Division, explains what it's all about: "The sun is waking up from a deep slumber, and in the next few years we expect to see much higher levels of solar activity. At the same time, our technological society has...

PALO ALTO, Calif., May 26 /PRNewswire/ -- The immense volume of data generated by the suite of instruments on NASA's Solar Dynamics Observatory (SDO) requires new tools for efficient identifying and accessing data that is most relevant to research investigations. Scientists at the Solar and Astrophysics Laboratory of the Lockheed Martin (NYSE: LMT) Advanced Technology Center (ATC) in Palo Alto have developed the Heliophysics Events Knowledgebase (HEK) to fill this need. The HEK system...
