Russell-McPherron Effect: Why "Cracks" In Earth's Magnetic Field Mean We Get Peak Auroras At Equinox
Most of the time, the Earth and Sun’s magnetic fields are misaligned, leaving our planet’s field less open to the aurora-causing effects of the solar wind. However, towards the equinox, the two fields ...
Ancient Asteroid Unlocks 4.6-Billion-Year-Old Magnetic Secrets of the Solar System
A weak magnetic field likely attracted matter inward, contributing to the formation of the outer planetary bodies, from ...
Four small planets discovered around one of the closest stars to Earth—an expert explains what we know
Barnard's Star is a small, dim star of the type that astronomers call red dwarfs. Consequently, even though it is one of the ...

Colliding plasma ejections from the sun generate huge geomagnetic storms
The sun periodically ejects huge bubbles of ... These interactions can amplify the impact of the CMEs on Earth's magnetic field, sometimes creating geomagnetic storms. Nearly one-third of CMEs ...
Colliding plasma ejections from the Sun generate huge geomagnetic storms − studying them will help scientists monitor future space weather
The Sun periodically ejects huge bubbles of plasma from its surface that contain an intense magnetic field. These events are called coronal mass ejections, or CMEs. When two of these ejections collide ...
