  • Coronagraphic observations of α Cen A using JWST's MIRI instrument.
  • Detection of a potential giant planet candidate, S1, in the habitable zone.
  • S1 has a temperature of 225 K and a radius of 1-1.1 RJup.
  • Orbital analysis suggests an eccentric (e ≈ 0.4) and inclined orbit.
  • Non-detections in follow-up observations leave the planet candidate unconfirmed.
  • Exozodiacal dust emission limits set unprecedented sensitivity constraints.
