Scientists think they have discovered the energy source of the spectacular colour displays seen in the northern lights.
New data from NASA's Themis mission, a quintet of satellites launched this winter, found the energy comes from a stream of charged particles from the sun flowing like a current through twisted bundles of magnetic fields connecting Earth's upper atmosphere to the sun.
The energy is then abruptly released in the form of a shimmering display of lights visible in the upper latitudes of the Northern Hemisphere, said principal investigator  Vassilis Angelopoulos of the University of California, Los Angeles.

Berkeley Lab Detectors Gather Data on Earth's Auroras, Radiation Belts, and the Solar Wind
Instruments known as solid-state telescopes (SSTs), built with detectors fabricated at Lawrence Berkeley National Laboratory and carried aboard the recently launched THEMIS mission, have delivered their first data on how charged particles in the solar wind interact with Earth's magnetic field to shape the planet's magnetosphere.

NASA's THEMIS mission successfully launched Saturday, Feb. 17, at 6:01 p.m. EST from Pad 17-B at Cape Canaveral Air Force Station, Florida.
THEMIS stands for the Time History of Events and Macroscale Interactions during Substorms. It is NASA's first five-satellite mission launched aboard a single rocket. The spacecraft separated from the launch vehicle approximately 73 minutes after liftoff. By 8:07 p.m. EST, mission operators at the University of California, Berkeley, commanded and received signals from all five spacecraft, confirming nominal separation status.

A Delta II expendable launch vehicle successfully launched NASA's Time History of Events and Macroscale Interactions during Substorms (THEMIS) spacecraft today marking the first east coast mission conducted by United Launch Alliance (ULA) since its formation Dec. 1, 2006.
The Delta II rocket lifted off from Space Launch Complex 17-B at 6:01 p.m., EST. Following a nominal 73-minute flight, the rocket deployed the payload.
