Pancaking and erosion can explain a lot of the structural change in magnetic flux ropes as they fly evolve during their supersonic flight through the inner solar system.Read More »Space Science & Space Physics
New research shows that solar radiation levels are growing 10% faster than previously believed and that the radiation environment in space will worsen with time.Read More »Planetary Sciences
A comprehensive look at how the solar wind is diverted around Mars, including the relative strength of the three biggest forces at work in this region. Read More »Space Science & Space Physics
Technological improvements, including an advanced thermal protection system and innovative solar arrays, have helped to get this mission off the drawing board.Read More »Space Science & Space Physics
A new study proposes a simpler theory to explain a class of electrons zipping around Earth, propelled by magnetic explosions.Read More »Space Science & Space Physics
A new analysis of satellite data could upend conventional wisdom about how solar storms produce their dangerous radiation—not from X-shaped mergers of magnetic field lines but from swirling vortices.Read More »
New calculations show that lightning-triggered plasma waves in Earth's magnetosphere absorb energy from slow particles and energize electrons to levels that can damage satellites severely.Read More »
When the Earth's and the Sun's magnetic fields meet, they realign in explosive and mysterious reconnections. Data suggest that plasma waves called kinetic Alfvén waves play a key role.Read More »
