Understanding The Magnetosphere Better Than Ever With Help From THEMIS
2013-02-20 10:47:18

NASA On Earth, scientists can observe weather patterns, and more importantly can predict them, through the use of tens of thousands of weather observatories scattered around the globe. Up in the space surrounding Earth -- a space that seethes with its own space weather made of speeding charged particles and constantly changing magnetic fields that can impact satellites — there are only a handful of spacecraft to watch for solar and magnetic storms. The number of observatories has...

WISE Captures The Heat From Orion's Sword
2013-02-06 09:58:22

NASA's Jet Propulsion Laboratory The tangle of clouds and stars that lie in Orion's sword is showcased in a new, expansive view from NASA's Wide-field Infrared Survey Explorer, or WISE. Orion, the famous hunter, is visible in evening skies throughout the world from about December through April. The constellation appears tranquil and still to the naked eye, but lying in its sword, at what appears to be a slightly fuzzy star, is a turbulent cauldron of stellar birth. WISE scanned the...

New Rocket Project Aims To Study Auroral Wind Of Northern Lights

Lawrence LeBlond for redOrbit.com - Your Universe Online For many in the extreme upper latitudes of the Northern Hemisphere, the Aurora borealis (better known as the Northern Lights) offer breathtaking displays of color and lights, dancing effortlessly across the night sky. These lights, which are caused by solar winds bouncing off the Earth´s upper atmosphere, are typically visible only around the Polar ℠auroral zone´ due to the strong magnetic forces around this region....

NASA IRIS Spacecraft
