IBEX ribbon

The IBEX ribbon is a narrow, arc-shaped structure of enhanced energetic neutral atom (ENA) emissions discovered by NASA’s Interstellar Boundary Explorer (IBEX) mission in 2009. The ribbon is a significant feature at the boundary of the heliosphere, the region of space dominated by the Sun’s influence.
