Monumental ‘Swiss cheese’ bubble surrounding Earth mapped in improbable new photographs

A huge,1,000-light-year-wide “superbubble” surrounds our planet. Now, astronomers have made the primary ever three-D map of its magnetic box.

The big construction, referred to as the “Native Bubble,” is a hole blob of diffuse, scorching plasma enclosed by means of a shell of chilly fuel and mud alongside whose floor stars shape. It’s only certainly one of a large number of hollows discovered within the Milky Manner — making our galaxy resemble a huge slice of Swiss cheese.
