Recent consternation over the discovery of The Band around the heliosphere, apparently a result of interaction with galactic magnetic fields. The big, heavy pennies beginning to drop?
Additional evidence for that interaction was the discovery of a “tail” of emissions in the underlying boundary landscape, which is apparently deflected in the direction of the galactic magnetic field as the ribbon seems to indicate.
“This galactic magnetic field may be a missing key to understanding how the heliosphere protects the solar system from galactic cosmic rays,” says Schwadron.
Also seen in the maps is the expected feature of the “nose” of the heliosphere. The nose represents the direction in which the solar system moves through the local part of the galaxy nearest to our Sun and that Schwadron compares to the “bow wave in front of a ship, which shows us how our motion through the galaxy compresses and deflects the material of the local galactic medium around our heliosphere.”
