The Voyager probes were designed for a "grand tour" of the solar system, when scientists realized the planets would be aligned in the 1970s. The spacecraft collected significant new knowledge and data: Voyager 2 sent back the first images of Uranus and Neptune. The probe found 11 new moons, and a significant magnetic field around Uranus. Voyager 2 also discovered that Jupiter's Red Spot was actually a large storm in the planet’s atmosphere. Both Voyager spacecraft are still in space, exploring what lies outside our solar system.
