Astronomers stuck on Earth miss a lot of astronomical wonders. Fortunately, the Curiosity Rover on Mars is helping to fill the gap with our first-ever look at another planet traversing our sun, as seen from a planet that's not Earth.
In addition to being the first time we've seen another planet cross the sun from another planet, this is also, in fact, our first glimpse of Mercury as it appears on Mars ever. If you're curious about contrasting the views from the red planet and our own blue marble, you'll have a bit of a wait, though. The next time Mercury's path across the sun will be visible from Earth won't be until May 9, 2016 and it will be almost another 70 years before Mars will be able to see the Earth traverse the sun.
