Solar physicists at the University of California, Berkeley, have captured for the first time the collision of a comet with the sun. Using instruments aboard NASA's twin STEREO spacecraft, four post-doctoral fellows at UC Berkeley's Space Sciences Laboratory were able to track the comet as it approached the sun and estimate an approximate time and place of impact. STEREO (Solar TErrestrial RElations Observatory), launched in 2006, consists of identical spacecraft orbiting the sun, one ahead of...

SSTL has today announced that it will launch the NigeriaSat-2 and NigeriaSat-X satellites on behalf of the National Space Research and Development Agency (NASRDA) by a Dnepr launch vehicle from Yasny, Russia on October 29th, 2010. NigeriaSat-2 is the most advanced small satellite ever to be launched, defining new standards in Earth observation and avionics. The spacecraft, which is based upon SSTL's flagship SSTL-300i platform, will be used primarily for resource management and mapping of the...

PALO ALTO, Calif., April 22 /PRNewswire/ -- Spectacular "first light" images and data from the three state-of-the art instruments on NASA's Solar Dynamics Observatory (SDO) were unveiled yesterday morning by NASA. The SDO spacecraft was launched aboard a United Launch Alliance Atlas V rocket from the Cape Canaveral Air Force Station on February 11, 2010. (Photo: http://www.newscom.com/cgi-bin/prnh/20100422/SF91131) Two of the SDO instruments were built at the Solar and Astrophysics...

Scientists from the University of Leicester have used observations from NASA's STEREO and ACE satellites to come up with more accurate predictions of when blasts of solar wind will reach Earth, Venus and Mars.  Anthony Williams will present the results at the RAS National Astronomy Meeting in Glasgow on Wednesday April 14th. We have recently been experiencing an unusually quiet and long-lasting solar minimum, and solar storms caused by Coronal Mass Ejections have been scarce. ...

When NASA's satellite operators need accurate, real-time space-weather information, they turn to the Community Coordinated Modeling Center (CCMC) of the Space Weather Laboratory at NASA's Goddard Space Flight Center in Greenbelt, Md. The CCMC's newest and most advanced space-weather science tool is the Integrated Space Weather Analysis (iSWA) system. The iSWA is a robust, integrated system provides information about space weather conditions past, present, and future and, unlike many other...

Imagine holding the entire sun in the palm of your hand. Now you can. A new iPhone app developed by NASA-supported programmers delivers a live global view of the sun directly to your cell phone. Users can fly around the star, zoom in on active regions, and monitor solar activity. "This is more than cool," says Dick Fisher, director of NASA's Heliophysics Division in Washington DC. "It's transformative. For the first time ever, we can monitor the sun as a living, breathing 3-dimensional...

Sometimes you really can believe your eyes. That's what NASA's STEREO (Solar Terrestrial Relations Observatory) spacecraft are telling researchers about a controversial phenomenon on the sun known as the "solar tsunami." Years ago, when solar physicists first witnessed a towering wave of hot plasma racing along the sun's surface, they doubted their senses. The scale of the thing was staggering. It rose up higher than Earth itself and rippled out from a central point in a circular pattern...

This just in: The Sun is blasting the solar system with croissants. Researchers studying data from NASA's twin STEREO probes have found that ferocious solar storms called CMEs (coronal mass ejections) are shaped like a French pastry. The elegance and simplicity of the new "croissant model" is expected to dramatically improve forecasts of severe space weather. "We believe we can now predict when a CME will hit Earth with only 3-hours of uncertainty," says Angelos Vourlidas of the Naval...
