Scientists now say that a massive eruption from the sun in April might have caused the Galaxy 15 satellite to become a "zombie." According to the U.S. Naval Research Laboratory (NRL), the explosion of plasma and magnetic energy occurred on April 3 and was observed by NASA's sun-watching STEREO spacecraft.  The NRL released new images of the solar storm last week. NRL officials said that the storm appears to have disabled Intelsat's Galaxy 15 communications satellite.  The zombie...

NASA's recently launched Solar Dynamics Observatory, or SDO, is returning early images that confirm an unprecedented new capability for scientists to better understand our sun's dynamic processes. These solar activities affect everything on Earth. Some of the images from the spacecraft show never-before-seen detail of material streaming outward and away from sunspots. Others show extreme close-ups of activity on the sun's surface. The spacecraft also has made the first high-resolution...

Polar skies glowed with ghostly auroras last week during the biggest geomagnetic storm of 2010. The event owed its origin to a solar eruption a few days earlier "“ revealed here in high-speed detail by ESA's small Sun-watcher Proba-2. Eruptions like this one have several components, most notably solar flares and Coronal Mass Ejections (CMEs). Solar flares are caused by sudden impulsive releases of magnetic energy from the surface of the Sun. The flare seen here took place at 11:54...

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. ...

An international group of solar and space scientists have built the most complete picture yet of the full impact of a large solar eruption, using instruments on the ground and in space to trace its journey from the Sun to the Earth. Dr Mario Bisi of Aberystwyth University will present the team's results, which include detailed images and a movie, on Tuesday April 13th at the RAS National Astronomy Meeting in Glasgow. Coronal mass ejections (CMEs) are giant eruptions of the Sun's atmosphere...

Over the last century, astronomers have become very aware of how just dynamic the Sun really is. One of the most dramatic manifestations of this is a coronal mass ejection (CME) where billions of tons of matter is thrown into space. If a CME reaches the Earth it creates inclement "Ëœspace weather' that can disrupt communications, power grids and the delicate systems on orbiting satellites. This potential damage means there is a keen interest in understanding exactly what triggers a...

Scientists are learning to predict giant solar storms that could, at any time, hit the Earth and produce cascading catastrophes From Sept. 1 to 2, 1859, the sun blasted out a massive, record-breaking coronal mass ejection (CME)--a huge eruption of highly charged gases and plasma that may have weighed as much as a billion tons. Racing through the solar system at several million miles per hour, the CME eventually collided with the Earth's magnetosphere--an invisible, atmospheric cocoon...
