Scientists using data from NASA's Voyager 2 spacecraft have observed the bubble of solar wind surrounding the solar system is not round, but has a squashed shape.
NASA's Voyager 2 spacecraft has followed its twin, Voyager 1, into the solar system's final frontier, a vast region at the edge of our solar system where the solar wind runs up against the thin gas between the stars.
The twin spacecraft have become a fixture of pop culture, inspiring novels and playing a central role in television shows, music videos, songs and movies from the 1980s and 1990s.
NASA's two venerable Voyager spacecraft are celebrating three decades of flight as they head toward interstellar space.
Voyager 1, already the most distant human-made object in the cosmos, reached 100 astronomical units from the sun on August 15 at 5:13 p.m. EDT.
