WD 1856+534b Archives

False-color image of the WD 1856+534 system constructed using three JWST/MIRI imaging bands: F770W (7.7 µm, blue), F1500W (15 µm, green), and F1800W (18 µm, red). The FOV measures 74′′× 113′′, corresponding to 1835 AU × 2802 AU at the system’s distance of 24.8 pc. The (blended) white dwarf and planet are the bluish-white star at the center of the image. The two bright stars near the right-hand side of the field of view (FOV) are mid-M dwarf companion stars to the white dwarf, at a projected separation of 1030 AU. Numerous colorful background stars and galaxies are visible throughout the image -- astro-ph.EP
