Crescent Earth!
Came across this beautiful photo on the net. Taken by the Rosetta satellite that is on a lo........ng mission to reach and drop an instrumented lander on the icy surface of a comet somewhere in 2014 after travelling some 7 billion kilometres, this image shows the earth in all its beautiful colours as a crescent. Every time we see it, it should remind us of our responsibility to preserve this beautiful planet.
