Mysterious Star System Conceals Hidden Planet in Galaxy-like Arms

A new study published in Nature Astronomy suggests that a giant planet, MWC 758c, may be responsible for the spiral arms observed in a distant star system. The gas giant's gravitational pull is believed to have stretched the surrounding gas in the protoplanetary disk, creating the spiral arms. The planet's redness made it difficult to detect, but the researchers used a red-sensitive telescope to confirm its existence. The findings could help in identifying hidden planets in other stellar systems.
