ALT Diagram showing the trajectories of NASA’s Voyager 1 and Voyager 2 spacecraft through the solar system. Both spacecraft launched in 1977—Voyager 2 on August 20 and Voyager 1 on September 5. Their paths curve outward from the Sun, passing by several outer planets. Voyager 1 flew by Jupiter on March 5, 1979, and Saturn on November 12, 1980, before heading upward out of the solar system. Voyager 2 took a longer path, encountering Jupiter on July 9, 1979, Saturn on August 25, 1981, Uranus on January 24, 1986, and Neptune on August 25, 1989, before exiting the solar system in a different direction.
ALT A field of galaxies in space, dominated by an enormous, bright-white elliptical galaxy that is the core of a massive galaxy cluster. Many other elliptical galaxies can be seen around it. Also around it are short, curved, glowing red lines, which are images of distant background galaxies magnified and warped by gravitational lensing. A couple of foreground stars appear large and bright with long spikes around them.
