Scientists believe that comets are the leftovers of the beginning of our solar system. They look at comets to see if they can find any clues to how it was made. This comet, named Lovejoy, is unique because it is carrying ethyl alcohol (the kind you can drink), a simple sugar and 19 other organic types of molecules.
There's enough alcohol on that comet to fuel a giant party but scientists are excited for another reason. This comet seems to support a theory that some of the molecules on earth came from comets crashing on the surface. Scientists are hoping to find a comet with the same kind of organic molecules that allowed life to start on Earth.
