Image: Uranus appears as a crescent as Voyager 2 soars past, starting its journey out of the solar system. “The human brain now holds the key to our future. We have to recall the image of the planet from outer space: a single entity in which air, water, and continents are interconnected. That is our home.” - David Suzuki Until Voyager reached the outer solar system we knew very little about the planets that inhabited this region of space. What we have discovered over years of exploration has both excited and mystified us.
