There is a constant outward flow of charged particles from the Sun. This flow, known as the solar wind, moves across space and reaches Earth every day.

March 2026 could be the best month for the northern lights until the mid-2030s, as celestial mechanics and solar activity combine for potentially potent results.

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

The Sun constantly emits streams of charged particles, known as the solar wind, from its outer atmosphere, the corona. These particles travel throughout the Solar System and interact with Earth's ...

High above Earth, where space and the planet’s magnetic field meet, powerful forces collide. Streams of charged particles known as the solar wind constantly flow from the Sun toward Earth. Most of the ...

A rare and captivating solar phenomenon, a butterfly-shaped hole in the Sun’s atmosphere, has led to warnings of potential geomagnetic storms, including dazzling auroras visible from Earth. As solar ...

Close-up measurements from NASA’s Parker Solar Probe are giving scientists an unprecedented look at how the solar wind gains energy and speeds away from the sun.

There may be more northern lights – or aurora borealis – sightings this spring. As we near the spring equinox, also known as the vernal equinox, on March 20, the Earth's magnetic field and solar wind ...

Earth’s magnetic field does not simply switch direction like a flipped light switch. It weakens, wanders, and reorganizes ...

NASA’s ESCAPADE mission studies how solar wind removed Mars’ atmosphere, using twin spacecraft to measure atmospheric escape, magnetosphere changes, and space weather impacts.

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 ...
