JWST directly images Saturn-mass exoplanet TWA 7 b

astronomy.com — June 25, 2025 at 10:00 PM UTC

The James Webb Space Telescope (JWST) has directly imaged an exoplanet, TWA 7 b, marking a first for the telescope and a significant advancement in exoplanet observation. The Saturn-mass exoplanet was discovered using JWST's Mid-Infrared Instrument (MIRI) equipped with a French-produced coronagraph. The discovery, published June 25, 2025, involved subtracting the light of the host star to reveal the planet within a debris disk. This breakthrough demonstrates JWST's capability to image smaller exoplanets, potentially leading to the discovery of Earth-sized worlds. The research team hopes to capture images of planets with even less mass in the future.
