A magnetosphere forms around any magnetized object, such as a planet, that is immersed within a stream of ionized gas, called plasma. Because Earth possesses an intrinsic magnetic field, the planet is ...

Scientists in a rare discovery have found “smiling electrons” inside Earth’s protective magnetic field. According to a new research study led by Jason Shuster, a UNH research assistant professor of ...

A powerful geomagnetic storm recently compressed Earth’s outer plasma shield so dramatically that satellites found themselves flying through a region of space that is usually safely above the planet’s ...

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

The presence of heavy ions in Earth’s magnetosphere alters the mass loading of the plasma, affects wave generation and propagation, and impacts the formation and transport of other energetic ion ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Today’s aurora alert proves the Sun is more dynamic than many may realize. The National Oceanic and Atmospheric Administration’s Space Weather Prediction Center announced today that the Sun had ...

When the plasma confined in the dipole magnetic field of RT-1 contains a significant ratio of high-temperature electrons (red particles), the spontaneous formation of a chorus emission (white emission ...

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 ...
