First direct image of 14 Her c. JWST/NIRCam coronagraphic imaging of the 14 Her system with the MASKA335R coronagraph (transmission indicated by gray shaded circles). North is up, east is left. Left: Prediction for the location of 14 Her c from a reproduction of the orbits presented in (G. F. Benedict et al. 2023), at the epoch of observation (MJD=60449), and the location of the point source detected in the F444W filter. Middle: A starlight-subtracted image taken with the F200W filter (1.755−2.227 µm), showing extended emission from a background galaxy at about 1. ′′5 to the SE from the host star. No other statistically significant point sources are apparent, as intended, given the cold temperature of the planet 14 Her c. Right: A starlight-subtracted image taken with the F444W filter (3.881−4.982 µm), showing extended emission from the same background galaxy, and a point source at 1. ′′1 to the SW with a contrast of 1 × 10−6 . The location of the point source, detected with a contrast of 9.6 × 10−7 , agrees within 1σ with the predicted location for the planet, so we conclude we have detected 14 Her c. -- (astro-ph.EP

JWST Coronagraphic Images of 14 Her c: a Cold Giant Planet in a Dynamically Hot, Multi-planet System

by Keith CowingJune 14, 2025June 12, 2025

Most observed multi-planet systems are coplanar, in a dynamically “cold” configuration of concentric orbits like our own Solar System.
