#JWST#Coronagraph#exoplanet , about 6x the mass of Jupiter and ~5-10º C in famous, nearby Epsilon Indi system, 12 light-years away! MIRI is so sensitive, almost unfair 😱 Congrats Lis Matthews & team! Thread by the first author ⬇️

Exoplanet Imaging alert. AF Lep b! Remarkable detection of a 3 Jupiter-mass exoplanet with JWST/NIRCam at 1.8 lambda/D (0.32") for a Lyot coronagraph that was designed to operate at 6 lambda/D (inner-working angle). The data processed by William Balmer, amazing job! arxiv.org/abs/2406.09528
