Magnetic bubbles could shield astronauts from radiation

Solar storms' dangers would lessen on long space trips

Deflector shields aren’t just for the starship Enterprise. One day, giant magnetic bubbles could protect spacecraft on long voyages.

By gathering charged particles floating through space, the bubbles could form a force field that flicks away radiation. If successful, the idea could offer scientists a solution to one of NASA’s stickiest problems: how to shield astronauts from harmful cosmic rays and solar eruptions.

Storms on the sun catapult charged particles into space at tremendous speeds, sa...
