Odd ‘bubble of space’ that ‘blocks cosmic rays’ surrounds solar system

The shape of an alien-looking “bubble of space” that “blocks cosmic rays” and sits just outside the solar system has been determined.

It’s believed the study, published in the journal Nature Astronomy, could help seek out life on other worlds by determining if other star systems have a similar bubble.
