In 1977, NASA sent the Voyager spacecraft to visit the gas giants Jupiter and Saturn. And though they're twins, the two spacecraft followed very different trajectories: Voyager 1 left the plane of the solar system after flying by Saturn on a path towards the edge of the heliosphere while Voyager 2 stayed in line with the planets to visit the outer ice giants Uranus and Neptune.
More than 30 years later, it's Voyager 1 that's in the news all the time since it is well on its way to becoming our first true interstellar spacecraft. But today, on the 32nd anniversary of Voyager 2's launch (Aug. 20, 1977), it's time to look back at some of the amazing sights it saw during its planetary flybys.
We might not think about it much, but as the only spacecraft to see the two furthest planets up close, the breathtaking images we have of Uranus and Neptune are all thanks to Voyager 2.
