Solar Plasma Wave Unleashed
2012-10-21 08:45:32

April Flowers for redOrbit.com - Your Universe Online NASA´s Solar Dynamics Observatory captured a spectacular solar eruption on Friday. A giant super-hot wave of solar plasma larger than the planet Earth erupted from the Sun at 4:15 a.m. EDT and was caught in amazing high-definition detail by the NASA spacecraft. "Once it started breaking away, the process only took 10 hours before it was out of sight," NASA media specialist Steele Hill explained in a photo description. "The...

Coronal Mass Ejection Captured By SOHO
2012-09-29 08:20:34

April Flowers for redOrbit.com - Your Universe Online At 10:23 pm EDT on September 27, 2012, NASA's Solar and Heliospheric Observatory (SOHO) captured an image of a particularly wide coronal mass ejection (CME) that erupted from the Sun. SOHO is an international collaborative effort between NASA and the European Space Agency (ESA) to study the Sun from its deep core to the outer corona. The SOHO spacecraft also studies the solar winds generated by solar events. The sun erupted in a...

Coronal Mass Ejections Linked To Sun's Interior
2012-09-25 04:30:27

April Flowers for redOrbit.com - Your Universe Online After forty long years of debates and theories and counter-theories, the community of solar physics scientists has still failed to come to a consensus about what causes the sun's powerful coronal mass ejections (CMEs). CMEs have profound "space weather" effects on land based power grids and satellites in near-Earth geospace. An international team of scientists explains the mysterious physical mechanisms behind the origin of CMEs in a...

Major Review Passed For NASA Mission To Study Magnetic Explosions
2012-09-06 07:20:05

On August 31, 2012 , NASA's Magnetospheric Multiscale (MMS) mission proved it was ready for its next steps by passing what's called a Systems Integration Review (SIR), which deems a mission ready to integrate instruments onto the spacecraft. The MMS mission is due to launch in late 2014. It will observe a mysterious process called magnetic reconnection, which creates explosive bursts of energy and which powers a variety of space phenomena from the aurora to giant eruptions of radiation on...

Researchers reproduce plasma loops to help understand solar physics In orbit around Earth is a wide range of satellites that we rely on for everything from television and radio feeds to GPS navigation. Although these spacecraft soar high above storms on Earth, they are still vulnerable to weather–only it's weather from the sun. Large solar flares–or plasma that erupts from the sun's surface–can cause widespread damage, both in space and on Earth, which is why researchers...

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. These latest Hinode results, to be discussed in a meeting at the University of St Andrews this week (Tuesday 14 August),...

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

Lee Rannals for redOrbit.com - Your Universe Online 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. Researchers discovered a new method to predict solar flares more than a day before they occur, which could help provide advanced warnings to protect satellites, power grids and astronauts. As the sun transitions into "solar maximum" next year, more solar activity is...

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

[ Watch the Video: STEREO Captures Fastest CME to Date ] Lee Rannals for redOrbit.com - Your Universe Online NASA's STEREO spacecraft has observed the fastest coronal mass ejection (CME) ever seen on the Sun. The Solar TErrestrial RElations Observatory (STEREO) clocked the massive eruption traveling between 1,800 and 2,000 miles per second as it ejected from the sun. NASA said this was the fastest CME ever observed by STEREO, which launched back in 2006. "Between 1,800 and...

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

Lee Rannals for redOrbit.com - Your Universe Online 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. SDO witnessed the image on the active region of the sun named AR 1532 in the 131 Angstrom wavelength. This wavelength is typically colorized as teal, and is particularly good for catching flares, NASA said. Solar flares emit powerful bursts of radiation, which...

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...
