Voyager 2’s Interstellar Arrival Was Kind of Familiar. That’s Surprising

Kimberly M. S. Cartier, News Writing and Production Intern for Eos.org by Kimberly M. S. Cartier 4 November 201917 June 2022

The spacecraft crossed the solar system’s edge at a different spot and in a different solar season than Voyager 1. Nevertheless, the border looked much the same in both spots.
