Nasa discovers interstellar magnetic field
Using data from NASA's Interstellar Boundary Explorer (IBEX) and simulations of the interstellar boundary, scientists have precisely determined the strength and direction of the magnetic field outside the heliosphere. Heliosphere is a bubble-like region of space around the Sun, which extends beyond Pluto's orbit. The study revealed the origin of so-called IBEX ribbon, which was discovered in 2009.
