Scientists at George Mason University discovered that a phenomenon called a giant magnetic rope is the source for solar storms. The researchers made the discovery by using images from the NASA Solar Dynamic Observatory (SDO) spacecraft. Scientists had previously been unable to prove that the magnetic rope was the cause of solar storms. However, using images taken by the Atmospheric Imaging Assembly (AIA) telescope aboard the SDO, the team was able to pinpoint an area of the sun where a...

The Cassini spacecraft has made the first observations from within the radio aurora of another planet than Earth. The measurements, which were taken when the spacecraft flew through an active auroral region in 2008, show some similarities and some contrasts between the radio auroral emissions generated at Saturn and those at Earth.  Results were presented last week by Dr Laurent Lamy at the European Planetary Science Congress in Rome, and recently published in Geophysical Research...

Using data from NASA's THEMIS mission, a team of University of Alberta researchers has pinpointed the impact epicenter of an earthbound space storm as it crashes into the atmosphere, and given an advance warning of its arrival. The team's study reveals that magnetic blast waves can be used to pinpoint and predict the location where space storms dissipate their massive amounts of energy. These storms can dump the equivalent of 50 gigawatts of power, or the output of 10 of the world's largest...

NASA's fleet of THEMIS spacecraft, launched less than 8 months ago, has made three important discoveries about spectacular eruptions of Northern Lights called "substorms" and the source of their power. The discoveries include giant magnetic ropes that connect Earth's upper atmosphere to the Sun and explosions in the outskirts of Earth's magnetic field. "The mission is only beginning but THEMIS is already surprising us," says Vassilis Angelopoulos the mission's principal investigator at the...

Canadian scientists help new NASA satellite project gain a closer look at the aurora borealis An international team of scientists -- including physicists from the University of Calgary -- will begin gathering the most detailed information yet about the ever-changing northern lights, as a multi-year research project enters its ultimate phase with the launch of five NASA satellites from Cape Canaveral next month. Researchers in the U of C's Institute for Space Research will play a critical role...

Hannes Olof Gösta Alfvén (May 30, 1908 - April 2, 1995) was a Swedish plasma physicist born in Norrköping, Sweden. Alfvén received his PhD from the University of Uppsala in 1934. His thesis was titled "Investigations of the Ultra-short Electromagnetic Waves." He was originally trained as an electrical power engineer and later moved on to research and teaching in the fields of plasma physics. Alfvén made many contributions to plasma physics, including theories describing the...
