Hubble sightlines for Voyager probes, illustration. NASA's Hubble Space Telescope is looking along the paths of NASA's Voyager 1 and 2 spacecraft as they journey through the solar system and into interstellar space. Hubble is gazing at two sight lines (the twin cone-shaped features) along each spacecraft's path. The telescope's goal is to help astronomers map interstellar structure along each spacecraft's star-bound route. Each sight line stretches several light years to nearby stars (four named here). Voyager 1 crossed the heliopause, the outer edge of the heliosphere boundary, in August 2012. Voyager 2 crossed the heliopause in November 2018. The probes were launched from Earth in 1977, and are now the most distant man-made objects. | |
