Lots of us are familiar with pictures of the planet Saturn and its unmistakable ring.
A NASA spacecraft the size of a golf cart has been directed to smash into an asteroid, with the intention of knocking it slightly off course.
The heat inside planets is left over from when they were formed.
Wormholes may be stable after all, a new theory suggests, contradicting previous predictions that these hypothetical shortcuts through space-time would instantly collapse.
