Fast CMEs Continue to Decelerate in the Outer Heliosphere
Most fast coronal mass ejections will be decelerated into ambient solar wind quickly in the inner heliosphere, but some of them continue the deceleration with an even larger amplitude beyond 1 AU.

The “Magnetic-less” Magnetotail Boundary
Most boundaries in space are governed by magnetic fields, but not far behind the Earth, where the field change across the magnetopause plays very little role in the pressure balance relationship.
