Scientists have finally made lemonade out of the origins of our lemon-shaped moon. While the moon may look, to quote crooner Dean Martin, like a big pizza pie — the real shape is a bit more similar to a lemon. To explain, a study published in the journal Nature says, one needs to go back to when the satellite first formed. Continue reading
