Teamwork: IBEX and TWINS observe a solar storm

On April 5, 2010, the sun spewed a two million-mile-per-hour stream of charged particles toward the invisible magnetic fields surrounding Earth, known as the magnetosphere. As the particles interacted with the magnetic fields, the incoming stream of energy caused stormy conditions near Earth. Some scientists believe that it was this solar storm that interfered with commands to a communications satellite, Galaxy-15, which subsequently foundered and drifted, taking almost a year to return to its station.

Each second, the sun hurls millions of tons of hot, charged plasma gas into space. This volatile "solar wind" buffets the magnetosphere, the magnetic field that surrounds the Earth, and can whip up geomagnetic storms that disrupt ce... Read Post

Plasma plumes help shield Earth from damaging solar storms

Academics / General Science : Science Codex (9 months ago)

The Earth's magnetic field, or magnetosphere, stretches from the planet's core out into space, where it meets the solar wind, a stream of charged particles emitted by the sun. For the most part, the magnetosphere acts as a shield to... Read Post

NASA's TWINS and IBEX spacecraft observe solar storm from inside and outside Earth's magnetosphere
