Elusive exoplanet is 'cosmic sculptor' that carved spiral arms of its star

Two images showing how a giant exoplanet is carving spiral arms round its parent star.

Astronomers have discovered a giant alien planet that is shaping the spiral arms developing in gas and dust around its parent star. 

The planet also happens to be the reddest planet outside the solar system, or 'exoplanet,' ever seen, scientists have said.
