Just how big is that comet the European Space Agency is going to land on?
Out in space, comets don’t seem that big compared to planets and all. But this chunk of rock and ice would rival the tallest mountains we know. Some have even created photos showing how it would tower over Los Angeles. Meanwhile in Australia, a Pizza Hut makes a major PR gaffe when it decides to throw in a free pet with every large pizza order. And the American-raised son of a terrorist decides to tell his story. All in this edition of the Global Scan.
