Look up at the sky

Image by Cassini

Did you look up at the sky when all of us on Planet Earth had our photo taken from a billion miles away last week? Judging from the response online, it seems lots of you did.

Now Cassini have released the first images of Earth and its moon as tiny dots - Earth is the blue dot on the left; the moon is fainter on the right hand side.

Linda Spilker, Cassini project scientist, said: "Cassini's picture reminds us how tiny our home planet is in the vastness of space, but also testifies to the ingenuity of the citizens of this tiny planet to be able to send a robotic spacecraft so far away from home to take a picture of Earth and study a distant world like Saturn."

After urging people to go outside and stare at the sky while the photo was being taken, I particularly liked Martijn Scheffers reply on Facebook. "So I walked out, looked up, started smiling. After 2 seconds random bypassers declared me crazy. Why would a man gaze into the sky they said..."

I'm glad you looked up anyway Martijn. The better question is: why wouldn't you gaze up at the stars?
