The Source of the Solar Wind Energy Discovered

  Using data from an aging NASA spacecraft, researchers have found signs of an energy source in the solar wind that has caught the attention of fusion researchers. NASA will be able to test the theory later this decade when it sends a new probe into the Sun for a closer look. The solar wind [continue reading]

Venus Behaves Like a Comet

  ESA’s Venus Express has made unique observations of Venus during a period of reduced solar wind pressure, discovering that the planet’s ionosphere balloons out like a comet’s tail on its night-side. The change in ionosphere of Venus during normal solar wind conditions (left) and reduced solar wind activity (right), as observed by ESA’s Venus Express [continue reading]

Solar Wind Delivers Water to the Moon and other Solar System Bodies

  Three years ago University of Tennessee, Knoxville, researchers helped to discover water on the surface of the Moon. Now, they are piecing together the origin of that water: solar wind. This microscope image shows a grain of agglutinate glass similar to those analyzed in the lunar surface-water study reported in Nature Geoscience. The specimen [continue reading]

 The Van Allen Radiation Belts to be Examined

  A University of Minnesota-led experiment is aboard NASA’s Radiation Belt Storm Probes (RBSP) mission, a probe of the forces that govern radiation in the Van Allen Radiation Belts. These two concentric, doughnut-shaped regions of space girdle the Earth and pose radiation danger to astronauts and spacecraft. The twin RBSP satellites and the Van Allen [continue reading]

How the Solar Wind Heats Up When it Should Not

  New research led by University of Warwick physicist Dr Kareem Osman has provided significant insight into how the solar wind heats up when it should not. The solar wind rushes outwards from the raging inferno that is our Sun, but from then on the wind should only get cooler as it expands beyond our [continue reading]

Waves in Magnetosphere's Thin Boundaries

  Exploiting a favourable configuration of ESA’s Cluster mission spacecraft, scientists have detected and characterised lower hybrid drift waves, a special kind of plasma waves that develop in thin boundaries both in space and in the laboratory. The measurement of fundamental properties of these waves was possible when two of the spacecraft were flying very [continue reading]
