Whilst the most powerful earthquake since records began hit Japan in 2011, triggering a massive tsunami which devastated much of the country, space scientists involved in one of the 'brightest' international Sun missions continued working tirelessly at the Institute of Space and Astronautical Science in Sagamihara, Japan, to capture new data from our turbulent star.

Predicting Solar Storms
2012-08-14 15:05:57

Predicting solar flares still remains a hit-or-miss task for scientists, but new research may shed more light on helping to predict just when the events could occur.

Fastest Coronal Mass Ejection Observed By STEREO
2012-08-14 11:57:42

NASA's STEREO spacecraft has observed the fastest coronal mass ejection (CME) ever seen on the Sun.

Solar Flare Captured By SDO
2012-07-31 13:47:29

NASA's Solar Dynamics Observatory (Solar Dynamics Observatory) captured a mid-level solar flare on Saturday, showing us that the sun is getting prepped for its solar maximum.

Art And Science Collide in New Solar Imaging Technique
2012-07-22 07:05:56

In what can be described as a melding of astronomy and post-Impressionist art, one NASA solar scientist has developed a new technique that uses bright, bold colors to share information about the heating and cooling of various parts of the sun.

Solar Corona Captured In Highest Resolution Ever
2012-07-21 05:29:44

A telescope launched on board a NASA sounding rocket earlier this month has captured the highest-resolution images of the sun's corona, the US space agency announced on Friday.

Coronal Mass Ejection Unlikely To Reach Earth
2012-07-21 04:31:52

A coronal mass ejection associated with a solar flare emitted early Thursday morning is unlikely to reach Earth, but it could affect one of the two STEREO satellites currently orbiting the sun.

Photosphere -- The photosphere of an astronomical object is the region at which the optical depth becomes one. In other words, the photosphere is the place where an object stops being transparent. It is typically used to describe the Sun or another star. Because stars are large balls of gas, they have no solid surface. However, there is a depth at which the gas stops being transparent to photons, and this depth provides a visual surface to the star. The Sun's photosphere has a...

Corona -- The corona is the luminous "atmosphere" of the Sun extending millions of kilometers into space, most easily seen during a total solar eclipse. An interesting feature of the corona is the fact that it is much hotter than the visible "surface" of the Sun; the photosphere is approximately 6000°C compared to the corona at over one million °C. The corona is much less dense than the photosphere, however, and so produces less light. The exact mechanism by which the corona is...

Chromosphere -- The chromosphere (literally, "color sphere") is a thin layer of the Sun's atmosphere just above the photosphere, roughly 10,000 kilometers deep. The chromosphere is more visually transparent than the photosphere. The most common solar feature within the chromosphere are spicules, long thin fingers of luminous gas which appear like the blades of a huge field of fiery grass growing upwards from the photosphere below. Spicules rise to the top of the chromosphere and then sink...

Solar Wind -- Solar wind, a stream of particles (mostly high-energy protons ~ 500 Kev) that is continually ejected from the surface of the Sun. The composition of this plasma is identical to the Sun's corona, 73% hydrogen and 25% helium with the remainder as trace impurities, and is ionized. Near Earth, the velocity of the solar wind varies from 200km/s-889km/s. The average is 450 km/s. Approximately 3000 tons of material is lost from the Sun every hour as solar wind. Since solar...

Solar Maximum -- The Sun, a roiling ball of plasma, occupies its place in space approximately 93 million miles from Earth. Though it seems simple to inhabitants of this planet -- the Sun shines, giving light and heat -- the processes occurring in the Sun are so complex that many scientists devote their careers to just one aspect of solar activity. Changes in the activity of the Sun particularly engage solar scientists. Whether fluctuations in the solar magnetic field, expulsions of...
