Enormous 'Swiss cheese' bubble surrounding Earth mapped in incredible new images
An enormous,1,000-light-year-wide"superbubble" surrounds our planet. Now, astronomers have made the first ever 3D map of its magnetic field.
Related: Earth is at the center of a 1,000-light-year-wide 'Swiss cheese' bubble carved out by supernovas The Milky Way, like many other galaxies, is filled with a magnetic field that gently steers stars, dust and gas into mind-bending structures such as gigantic, bone-like filaments. Astronomers are unsure what gives rise to galactic magnetic fields. The Milky Way’s magnetic field, though considerably weaker than Earth’s, permeates throughout our galaxy and deep its outer halo, subtly influencing the formation of everything around it.
