NASA "Rocket Scientist" presents program on the science of the Northern Lights WASHINGTON, Jan. 26 /PRNewswire-USNewswire/ -- On Thursday, January 29 at noon, the National Archives will celebrate the 50th Anniversary of Alaska Statehood with a program on the northern lights.
Researchers announced on Thursday that current satellite surveillance has exposed the biggest breach ever seen in the magnetic field that shields the Earth from the majority of the sun's aggressive rays.
GREENBELT, Md., Dec. 16 /PRNewswire-USNewswire/ -- Earth's magnetic field, which shields our planet from particles streaming outward from the Sun, often develops two holes that allow the largest leaks, according to researchers sponsored by NASA and the National Science Foundation.
NASA's five THEMIS spacecraft have discovered a breach in Earth's magnetic field ten times larger than anything previously thought to exist.
NASA landed on Mars, photographed distant worlds, added to the International Space Station, took part in a lunar science mission with India and made major progress toward returning astronauts to the moon as the agency celebrated its 50th birthday in 2008.
Researchers have discovered 'magnetic portals' forming high above Earth that can briefly connect our planet to the Sun. Not only are the portals common, one space physicist contends they form twice as often as anyone had previously imagined.
U.S. scientists working with NASA said they've uncovered the source of substorms in space that fuel the explosive energy behind the northern lights.
MINNEAPOLIS, July 24 /PRNewswire-FirstCall/ -- Alliant Techsystems reported today that the constellation of five micro satellites it built for NASA's THEMIS (Time History of Events and Macroscale Interactions during Substorms) mission has successfully demonstrated how satellites can work together to collect data, which in this case, advances the scientific understanding of the Earth's atmosphere.
Researchers using a fleet of five NASA satellites have discovered that explosions of magnetic energy a third of the way to the moon power substorms that cause sudden brightenings and rapid movements of the aurora borealis, called the Northern Lights.
