Mercury’s ancient magnetic poles were far from the location of its poles today, implying its magnetic field, like Earth’s, changed over time, a new study says.

A special kind of streaked aurora has been found to track disturbances in near-Earth space from the ground. Known as structured diffuse aurora, it was recently discovered, with the help of NASA spacecraft and instruments, that these faint lights in the night sky can map the edges of the Van Allen radiation belts — hazardous concentric bands of charged particles encircling Earth.
The Solar wind-Magnetosphere-Ionosphere Link Explorer (SMILE) mission is still four years away from launch, but scientists are already using existing ESA satellites, such as the XMM-Newton X-ray observatory and the Cluster mission studying Earth’s magnetosphere, to pave the way for this pioneering venture.

High school students listening to audio tracks of NOAA satellite data have identified the sounds of solar storms buffeting Earth’s magnetic field. The results of a UK-led citizen science project suggest that the approach of converting physical data into sound signals could help NOAA and other scientists make sense of massive amounts of data from satellites and other instruments.

New observations of Uranus being buffeted by shock waves from the sun have revealed auroral activity and fresh clues to the workings of the seventh planet’s unusual magnetosphere, the region of space dominated by its magnetic field.
