The Earth is surrounded by an invisible barrier that was thought to prevent highly energetic electrons from reaching closer to our planet. But in ...

Scientist using the Cassini spacecraft’s Magnetospheric Imaging instrument (MIMI) have detected a new, temporary radiation belt at Saturn, located around the orbit of its moon Dione at about 377,000 ...

For the first time, astronomers have spotted a band of radiation surrounding an object outside our solar system. A belt of energetic electrons encircles a Jupiter-sized body about 18 light-years from ...

Typically when we think of radiation, we might picture mutated monsters or the fate of poor Marie Curie, the pioneering scientist and two-time Nobel prize laureate who died from her research into the ...

Astronomers have described the first radiation belt observed outside our solar system, using a coordinated array of 39 radio dishes from Hawaii to Germany to obtain high-resolution images. The images ...

Mercury was long considered the exception to the rule that magnetic planets have radiation belts similar to Earth's Van Allen belts, but a new study by University of Michigan Engineering and the ...

Of all the solar system’s planets, Mercury is an oddball. Despite being closest to the Sun, it’s not the hottest planet. It quickly zips around the Sun every 88 days in the shape of a squashed oval ...

Our planet is nestled in the center of two immense, concentric doughnuts of powerful radiation: the Van Allen radiation belts, which harbor swarms of charged particles that are trapped by Earth’s ...

The first images of an extrasolar radiation belt were obtained by combining 39 radio telescopes to form a virtual telescope spanning the globe from Hawaii to Germany. (Image credit: Melodie Kao, Amy ...
