The heliosphere at the end of the simulation at 44 years in the meridional plane at y = 0 au (for the model coordinate system, see ‘Description of the numerical model’ in Methods). Contours are speed. The heliosphere shrinks to 0.22 au at the nose. It maintains a long cometary shape and exposes all the planets to the cold dense ISM material.-- Nature Astronomy
