Flux ropes (simulated, right) are structures made up of magnetic field lines wrapping around each other like a rope, that look similar to tornadoes on Earth. NOAA, Mojtaba Akhavan-Tafti and Chip Manchester

‘Space tornadoes’ could cause geomagnetic storms – but these phenomena, spun off ejections from the Sun, aren’t easy to study

Unprecedented simulations show the formation of space tornadoes capable of causing strong geomagnetic storms around Earth, calling for earlier and more accurate warnings.

What are solar storms and the solar wind? 3 astrophysicists explain how particles coming from the Sun interact with Earth

Space weather isn’t referring to rain clouds that float through the galaxy. Instead, it’s caused by massive explosions of particles that shoot out from the Sun.
Wandering magnetic fields would have had noticeable effects for humans. Maximilian Schanner (GFZ Helmholtz Centre for Geosciences, Potsdam, Germany)

Weird space weather seems to have influenced human behavior on Earth 41,000 years ago – our unusual scientific collaboration explores how

Two geophysicists and an archaeologist teamed up to connect space weather 41,000 years ago to human behaviors that might have been in response – and show the value in cross-discipline teamwork.

2 solar probes are helping researchers understand what phenomenon powers the solar wind

For years, researchers have wondered what energy source allows the solar wind − a projection of charged particles from the Sun − to rush by at hundreds of miles a second.
Scientists have been studying lunar samples brought back from Apollo missions to understand the geologic history of the Moon. NASA

Moon lacked a magnetic field for nearly all its history – new research resolves mystery sparked by rocks brought back on Apollo

Without a magnetic field, the Moon’s surface is exposed to solar wind. These could have been depositing resources like water and potential rocket fuel on the Moon’s surface for billions of years.
