A team of astronomers led by Dr. Anna Ordog at the University of Calgary has identified a magnetic-field reversal slicing ...

The Sun constantly emits streams of charged particles, known as the solar wind, from its outer atmosphere, the corona. These ...

NASA invites the public to join the Space Umbrella project, analyzing MMS data to study magnetic reconnection and solar wind interactions affecting space weather and technology.

A stream of charged particles known as the solar wind flows from the Sun toward Earth. Here, it meets the Earth’s magnetic fields, which shield our planet like a giant umbrella. The Space Umbrella ...

Scientists have identified a new source of energetic particles near the Sun. These definitive observations were made by instruments aboard NASA's Parker Solar Probe, which detected the powerful ...

Invisible yet vital, Earth’s magnetic field plays a crucial role in shielding the planet from harmful solar radiation and cosmic particles. Generated deep within the Earth’s molten outer core, this ...

Earth is fortunate in having a magnetic field: it protects the planet and its life from harmful cosmic radiation. Other planets in our solar system—such as Mars—are constantly bombarded by charged ...

An SwRI-led study identified particles accelerated to extremely high energies by magnetic reconnection near the Sun. As NASA’s Parker Solar Probe (trajectory shown in green) crossed the heliospheric ...
