[ 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...

Image 1 - Space Weather Prediction Model Improves NOAA’s Forecast Skill

[ 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

  [ 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...

WASHINGTON, Aug. 18, 2011 /PRNewswire-USNewswire/ -- NASA spacecraft observations and new data processing techniques are giving scientists better insight into the evolution and development of solar storms that can damage satellites, disrupt communications and cause power grid failures on Earth. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) The solar storms, called Coronal Mass Ejections (CMEs), are being observed from NASA's twin Solar Terrestrial Relations Observatory,...

Using data collected by NASA's STEREO spacecraft, researchers at Southwest Research Institute and the National Solar Observatory have developed the first detailed images of solar wind structures as plasma and other particles from a coronal mass ejection (CME) traveled 93 million miles and impacted Earth. The images from a December 2008 CME event reveal an array of dynamic interactions as the solar wind, traveling at speeds up to a million miles per hour, shifts and changes on its three-day...

baudekin
  • A rich embroidered or brocaded silk fabric woven originally with a warp of gold thread.
'Baudekin' seems to be an alternative form of 'baldachin,' from the Italian 'Baldacco,' Baghdad, the city where the material was made.
