Astronomers make 1st-ever 3D map of Local Bubble’s magnetic fields

Interstellar cartographers have for the first time mapped in 3D the magnetic field swept up by the Local Bubble. 

The Local Bubble is a cavity at least 1,000 light-years wide in the interstellar gas around the solar system — a ‘superbubble’ in interstellar space. The Local Bubble was blown out by a series of supernovas between 10 million and 20 million years ago, and is one of many such bubbles in the interstellar medium that riddle our Milky Way galaxy and others like the cavities in Swiss cheese.
