December 25 Solar Storm Could Knock Out Radio Signals
2011-12-29 04:49:43

Scientists have warned of a major solar storm hitting the Earth that could possibly knock out radio signals. Experts expect radio blackouts for a few days after the radiation from the coronal mass ejection (CME) hits our planet. The flare is part of a larger increase in activity in the Sun, which is expected to peak around 2013. "Category G1 (Minor) geomagnetic storms are expected 28 and 29 December due to multiple coronal mass ejection arrivals," the National Oceanic and Atmospheric...

Solar storms and associated Coronal Mass Ejections (CMEs) can significantly erode the lunar surface according to a new set of computer simulations by NASA scientists. In addition to removing a surprisingly large amount of material from the lunar surface, this could be a major method of atmospheric loss for planets like Mars that are unprotected by a global magnetic field. The research is being led by Rosemary Killen at NASA's Goddard Space Flight Center, Greenbelt, Md., as part of the...

NASA: Killer Solar Flares A Physical Impossibility
2011-11-11 11:09:25

[ Watch the Video ] Given a legitimate need to protect Earth from the most intense forms of space weather — great bursts of electromagnetic energy and particles that can sometimes stream from the sun — some people worry that a gigantic "killer solar flare" could hurl enough energy to destroy Earth. Citing the accurate fact that solar activity is currently ramping up in its standard 11-year cycle, there are those who believe that 2012 could be coincident with such a flare....

[ Watch Video 1 ] | [ Watch Video 2 ] On October 25, 2006 a Delta II rocket launched from Cape Canaveral carrying two nearly identical spacecraft. Each satellite was one half of a mission entitled Solar TErrestrial RElations Observatory (STEREO) and they were destined to do something never done before — see the entire sun simultaneously. The sun rotates, of course, so there's no part of the sun we haven't at some point observed from our vantage point on Earth. But watching this...

[ Watch the Video ] NOAA is now using a sophisticated forecast model that substantially improves predictions of space weather impacts on Earth. Better forecasts offer additional protection for people and the technology-based infrastructure we use daily. Explosions in the sun´s outer atmosphere — tracked and forecast by NOAA scientists — can cause geomagnetic and solar radiation storms at Earth that can impede the operation of electrical power grids, interfere with the...

NASA will begin development and testing of two science instruments, in cooperation with the European Space Agency (ESA), to be placed on ESA's newly selected Solar Orbiter mission. The spacecraft will study the sun from a closer distance than any previous mission. At its closest approach, the European-led project will operate approximately 21 million miles from the sun's surface, near the orbit of Mercury, roughly 25 percent of the distance from the sun to the Earth. This unique vantage...

Sungrazing Comet - Wrong Place, Wrong Time
2011-10-05 11:16:14

[ Watch the Video ] NASA's Solar And HelioSpheric Observatory (SOHO) recently witnessed a sungrazing comet being eaten up by a coronal mass ejection (CME). The comet that disintegrated on October 2, 2011 was a sungrazing comet of the type known as a Kreutz Sungrazer, according to NASA. The Kreutz Sungrazers are a family of comets known for taking orbits extremely close to the Sun.  This family is believed to be fragments of one large comet that broke up several centuries ago....

The Secret Lives Of Solar Flares
2011-09-20 09:12:45

  [ View the Video ] One hundred and fifty two years ago, a man in England named Richard Carrington discovered solar flares. It happened at 11:18 AM on the cloudless morning of Thursday, September 1st, 1859. Just as usual on every sunny day, the 33-year-old solar astronomer was busy in his private observatory, projecting an image of the sun onto a screen and sketching what he saw. On that particular morning, he traced the outlines of an enormous group of sunspots. Suddenly,...

  A third and fourth flare have erupted from sunspot 1283. The third came on September 7 at 6:36 PM ET, and was categorized as an X1.8 by the GOES spacecraft, making it the second X-class flare within 24 hours. There was a coronal mass ejection (CME) associated with all three of the recent flares, but none of them are expected to travel directly toward Earth, and the first two were unlikely to cause aurora. NASA computer models suggest that the latest CME may give a glancing...
