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 ...

The great solar storm of May 2024, which sparked beautiful auroral displays over much of the world, also created two new radiation belts that were observed with a satellite that came back from the ...

For more than a decade, a clean rule organized our understanding of planetary magnetospheres: every planet with a strong enough magnetic field develops radiation belts. Every planet, that is, except ...

The May 2024 solar storm created two extra radiation belts, sandwiched between the two permanent Van Allen Belts. One of the new belts, shown in purple, included a population of protons, giving it a ...

Far from the Sun, Uranus sits tipped on its side, carrying a magnetic system unlike any other planet’s. Its equator tilts about 97.7 degrees relative to its orbit, so the planet spends long stretches ...
