Scientists propose launching a giant 'airbag' into space to protect us from solar superstorms ‪— and experts say it's 'quite feasible'

A giant airbag in space sounds like science fiction, but researchers say it could be our best defense against the sun's most violent outbursts.

Scientists have proposed a satellite constellation called StormWall, designed to cushion Earth from solar "superstorms," massive waves of charged plasma that periodically erupt from the sun and race toward our planet. These coronal mass ejections can cripple power grids, knock out satellites, and cause trillions of dollars in damage.

We've had a recent reminder of the stakes. Over the past few years, as the sun moved through its most active phase, dozens of solar storms have rolled through, painting stunning auroras across the sky but also rattling infrastructure.

StormWall would essentially position a shield between Earth and the worst of what the sun can throw at us. Researchers say the concept is, quote, "quite feasible," a surprisingly optimistic assessment for a challenge that has long seemed unsolvable.
