Solar Storm Expected To Reach Earth Saturday Morning
2012-07-14 04:10:29

A solar storm, scheduled to arrive Saturday morning and last through the end of the day on Sunday, is expected to put on a show for sky-gazers but should otherwise have little to no effect, according to scientists.

NASA Launching New Sun Observing Spacecraft Thursday

While the nation shoots off plenty of fireworks for the Fourth of July, NASA will be sending off its own rocket the next day.

Doppler Techniques Could Help Predict Solar Storms

Scientists are using Doppler techniques that may be able to take predicting space weather to a new level and understanding.

Images Of Extreme Solar Activity Provide Origins Of Powerful Space Storms
2012-07-02 09:58:45

An international team of scientists have for the first time captured and identified images of an upward surge of the Sun’s gases into quiescent coronal loops, a discovery that provides one more step in the understanding of the origins of extreme storms in outer space, which are known to wreak havoc on satellite systems and power grids here on Earth.

Incoming Coronal Mass Ejection Coming On June 16
2012-06-15 13:39:44

The sun is a ferocious, hot mess, and this week it showed off through a coronal mass ejection just how messy it can get. An active region on the sun fired off two M-class flares and two coronal mass ejections (CMEs) this week.

NASA said that its Fermi Gamma-ray Space Telescope detected the highest-energy light ever associated with an eruption on the sun on March 7.

Venus Transit Will Help RHESSI Improve Sun Measurements
2012-06-05 08:42:08

The RHESSI (Ramaty High Energy Solar Spectroscopic Imager) satellite focuses on the highest energy x-rays and gamma-rays produced by the sun, helping to observe solar flares of all shapes and sizes.

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...
