Hell, in the last few years alone intrepid probes have hurtled through unexplored corridors of space, bringing the planets, their moons and other rocky inhabitants of the system into sharper focus than ever before. Let's take a walk through this new high-res version of our neighborhood of space.
Trailblazing spacecraft have not only returned stunning images for us to fawn over recently, they've returned important observations with great implications for our understanding of the universe. One great example of this is a discovery made via the Rosetta spacecraft, which became the first spacecraft to enter orbit around a comet in 2014.
While circling the comet 67P/Churyumov-Gerasimenko, Rosetta made the first unambiguous detection of key amino acids and molecules that could serve as the building blocks for life on Earth, throwing further weight behind the theory that comets may have brought about our beginnings. Rosetta returned a stunning collection of photos detailing its rugged landscape.
