New satellite-based analysis explains how energy carried by Alfvén waves moves from Earth’s magnetosphere into the atmosphere to generate auroral light emissions.

As you probably know, Earth's magnetosphere, 'the invisible bubble of magnetic fields and electrically charged particles that surrounds and protects the planet from the periodically lethal radiation ...

One of the features of Earth that is critical to protecting life as we know it is the magnetosphere. The Earth's magnetosphere is a magnetic field that protects the planet from the constant ...

A flyby of Uranus in 1986 is where we gathered much of our knowledge about the distant ice giant, but new research has found that this may not have been a standard representation of the planet's ...

The solar wind is a constant feature of the solar system – except on Christmas Day 2022 when it suddenly vanished completely. The odd event was detected by a NASA spacecraft orbiting Mars, which found ...

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 ...

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 ...

San Antonio — Oct. 23, 2007 — Space physicists have long assumed that the magnetosphere at Jupiter circulates that planet’s magnetic field in the same way as Earth. At Earth, this circulation drives ...

Two cubesats designed to study the Earth's magnetic field and to look for exoplanets around nearby stars rode to space on Monday (Sept. 27) with NASA's new Landsat 9 Earth observation mission. The two ...

Scientists report a method to study smaller magnetospheres, sometimes just millimeters thick, in the laboratory. The new experimental platform combines the magnetic field of the Large Plasma Device ...
