sci-news.com – In November 2018, NASA’s Voyager 2 spacecraft became only the second human-made object to cross the outer edge of the Sun’s heliosphere, the bubble of space filled by the solar wind. In a series of five papers in the journal Nature Astronomy, researchers describe what they observed during and since Voyager 2’s historic exit.
