The 'star' on a black spot near the center represents a filter (of sorts) that was used with the telescope to reduce the impact of the stars' light, to facilitate the capture of the planet.

NASA description: This image of the gas-giant exoplanet Epsilon Indi Ab was taken with the coronagraph on NASA’s James Webb Space Telescope’s MIRI (Mid-Infrared Instrument). A star symbol marks the location of the host star Epsilon Indi A, whose light has been blocked by the coronagraph, resulting in the dark circle marked with a dashed white line. Epsilon Indi Ab is one of the coldest exoplanets ever directly imaged.
