Look out, incoming killer asteroid! Or is it..? Astronomers left red-faced after false alarm

Astronomers were left red-faced after accidentally confusing the European space probe Rosetta with a killer asteroid heading for Earth.

After spotting an unidentified object hurtling through space and due to fly worryingly close to Earth, space experts at the Minor Planet Centre, the group that scans the skies for incoming asteroids, were on the verge of issuing a worldwide warning of impending doom.

Emergency emails were prepared and astronomers worldwide prepared to tell us all the worst: that a deadly asteroid was due to skim our planet by only 3,500 miles and there was a very real risk that it might collide with Earth.  ...

The end of the world...not.
