New model accurately predicts harmful space weather

A new, first-of-its-kind space weather model reliably predicts space storms of high-energy particles that are harmful to many satellites and spacecraft orbiting in the Earth's outer radiation belt. A paper recently published ...

Relativistic electrons uncovered with NASA's Van Allen Probes

Earth's radiation belts, two doughnut-shaped regions of charged particles encircling our planet, were discovered more than 50 years ago, but their behavior is still not completely understood. Now, new observations from NASA's ...

Scientists launch CubeSats into radiation belts

Twin, pintsized satellites built in part at the University of New Hampshire's Space Science Center will be launched into orbit from Vandenberg Air Force Base in California at 9:20 a.m. (EST) Thursday, January 29, 2015.

Study of electrons in space could help weather forecasting

Researchers have discovered a formerly undetected impact of space weather on the polar atmosphere, which may explain some previously unexplained variations in winter weather patterns. Their results, published today (Tuesday ...

Scientists launch 'CubeSats' into radiation belts

Twin, pintsized satellites built in part at the University of New Hampshire's Space Science Center by UNH graduate student Alex Crew were launched into orbit from Vandenberg Air Force Base in California just before midnight ...

NASA spacecraft records 'Earthsong'

Nobody ever said anything about singing, though. A NASA spacecraft has just beamed back a beautiful song sung by our own planet.

Ames celebrates the 40th anniversary of Pioneer 10

Launched on March 2,1972, Pioneer 10 was the first spacecraft to travel through the Asteroid belt, and the first spacecraft to make direct observations and obtain close-up images of Jupiter. Famed as the most remote object ...

Solar Cycle Driven by More than Sunspots

(PhysOrg.com) -- Challenging conventional wisdom, new research finds that the number of sunspots provides an incomplete measure of changes in the Sun's impact on Earth over the course of the 11-year solar cycle. The study, ...
