A new method for deleting starlight from telescope images

Caption

Left: JWST/NIRCam observation of star 51 Eri A using a previous, standard method to subtract the glare of the star. This method did not detect the planet 51 Eri b in the original analysis, whose expected location is marked with a dashed circle. Middle: Using their FLIP method to subtract the glare of the star in the same observation, a research team led by Rodrigo Ferrer-Chavez obtained a significant detection of exoplanet 51 Eri b. Right: Simulated image of 51 Eri b, highlighting that the planet is detected at its expected location and that the planet signal has the expected morphology. The location of the star 51 Eri A is marked with a star symbol.
