JWST captures possible Saturn-sized exoplanet

The new world may be the first the telescope has discovered by direct imaging

JWST has spotted evidence of a planet lurking in a disc of debris orbiting nearby star TWA 7. The object, known as TWA 7b, could be a young, cold planet with a mass similar to that of Saturn - around 100 times more massive than Earth.

Debris discs orbit both young and old stars and are filled with dust and rocky material. They often contain gaps, thought to be created by planets forming around these stars. However, such a planet has never been discovered before.
