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

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

[ 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

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...

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

[ Watch the Video ] redOrbit Staff & Wire Reports - Your Universe Online A coronal mass ejection (CME) associated with a solar flare emitted early Thursday morning is unlikely to reach Earth, but it could affect one of the two Solar Terrestrial Relations Observatory (STEREO) satellites currently orbiting the sun, NASA officials posted on the agency's official website. According to the US space agency, the sun emitted a mid-level (M7.7) flare on July 19. The flare, which began at...

Aurora Australis Glowing Over Concordia Station
2012-07-20 15:27:23

A stunning image showing Aurora Australis — the Southern Lights — glowing over Concordia station in the Antarctic, one of the remotest places on Earth, on 18 July 2012. It was taken by ESA-sponsored scientist Alexander Kumar and his colleague Erick Bondoux from about 1 km from the station, located in the Antarctic at 75°S latitude. The French—Italian Concordia station's programme of research includes glaciology, human biology and the atmosphere. ESA uses the base to...

Plasma Waves Move Faster Than Shockwaves

Lawrence LeBlond for redOrbit.com - Your Universe Online The Sun and the dynamic space weather system that envelops the Earth are what researchers are trying to get a better understanding of with the help of Heliophysics nuggets -- collections of early scientific results, new research techniques and instrument updates. More than 99 percent of the matter found in the universe resembles nothing like what we have here on Earth, according to scientists from NASA´s Goddard Space Flight...

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

[ Watch the Video ] redOrbit Staff & Wire Reports - Your Universe Online 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. According to the Associated Press (AP), the storm began on Thursday, as the sun unleashed a powerful solar flare -- the sixth recorded by scientists this year. The NOAA Space Weather Prediction...
