NASA Observatory Captures Another X-Class Solar Flare
2012-10-23 15:32:34

[WATCH VIDEO: Active Region On The Sun Emits Another Flare] Lee Rannals for redOrbit.com — Your Universe Online NASA said its Solar Dynamics Observatory (SDO) captured the sun erupting with an X1.8 class solar flare on Monday. The solar flare came from an active region on the left side of the sun known as AR 1598, which has been the source of weaker flares. The "X-class" solar flares are the most intense flares, with the number near the X representing its intensity. An X2...

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...

Astronomers Look Long At Coronal Mass Ejections
2012-09-20 18:54:36

Lee Rannals for redOrbit.com — Your Universe Online Astronomers reported in The Astrophysical Journal they have a better understanding of the temperatures of the coronal cavities in Coronal Mass Ejections (CMEs). Terry Kucera, a solar scientist at NASA's Goddard Space Flight Center in Greenbelt, Maryland, along with colleagues, set out to understand the structure of CMEs, even before they erupt. CMEs are eruptions that take place on the sun that can travel toward Earth and...

IDEA! Coronal Mass Ejection From The Sun
2012-08-28 14:51:12

Watch the Video: Lightbulb Shaped CME Lee Rannals for redOrbit.com - Your Universe Online The sun sent off another coronal mass ejection (CME) last week, but this time the plasma burst showed up in the form of a light bulb. The Solar and Heliospheric Observatory (SOHO) caught the CME light bulb with its Large Angle and Spectrometric Coronagraph (LASCO) C2 instrument. This instrument is able to take images of the solar corona by blocking the light coming directly from the Sun with...

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...

Lee Rannals for redOrbit.com - Your Universe Online Scientists are warning that power grids, communications and satellites could be knocked out by a massive solar storm within the next two years. The sun will be reaching its peak in its 10-year solar activity cycle, putting the Earth at a greater risk from solar storms. During this peak, scientists say there is a heightened risk that a solar storm could knock out the communication systems that we rely on. "Governments are taking...

Great Idea Had by The Sun
2012-07-23 16:10:30

A light bulb-shaped eruption leaps from the Sun and blasts into space in this archival image from the ESA/NASA Solar and Heliospheric Observatory, SOHO. SOHO captured the scene on 27 February 2000, watching as a large filament rose from the Sun´s broiling atmosphere and evolved into the coronal mass ejection loop seen here. A coronal mass ejection — or CME — is a huge cloud of magnetised plasma ejected from the Sun´s atmosphere — the corona — and...
