While Earth's atmosphere and magnetic field protect the planet from these solar events, Mars has no such protection. But the sun's solar particles could be a boon for studies of — and travel to ...

Relatively early in its history, Mars lost its magnetic field, which allowed the solar wind to claw away most of its atmosphere; with that, much of the water sublimed into space. It’s in the ...

We are protected from most of this radiation thanks to our planet’s atmosphere and magnetic field, known as the magnetosphere. But Mars has no magnetosphere, and its atmosphere is over 100 times ...

For decades, something strange has lurked inside the icy giants of our solar system. Uranus and Neptune, distant blue worlds ...
