An international research team has discovered clear signs of galactic migration in our neighbor, the Andromeda galaxy M31.

Mapped the Local Bubble of the Solar System

Astronomers have traced the magnetic field of the local bubble using data obtained from Planck and Gaia. In the image, the pink and purple vector lines on the surface of the bubble represent the orientation of the discovered magnetic field. Credit: Theo O'Neill / World Wide Telescope

Scientists have discovered and mapped the local bubble surrounding our Solar System, influenced by a strong magnetic field
