Astronomers discover elusive planet responsible for spiral arms around its star

Scientists have discovered a young exoplanet, MWC 758c, that may be generating the spiral arms in its infant planetary system. The planet's massive size is estimated to be at least twice the mass of Jupiter, yet it was invisible to other telescopes due to its reddish color, which makes it more difficult to detect.
