Announcement time: Early 2025, through a scientific announcement from an international research team coordinated by NASA and ESA.
Tools used: James Webb Space Telescope (JWST) and Transiting Exoplanet Survey Satellite (TESS).
Star system: These planets are located in star systems 40 to 100 light years from Earth, mainly in the constellations Cygnus and Cancer.
Provisional designation:
GLI ESOPIANETI DELLA STELLA LHS 1140 VIDEOCharacteristics of the three planets:
Planet Radius from Earth Distance from star Location of habitable zone Possibility of atmosphere Kepler-186f II~1.1x Sufficient for liquid water Signs TOI-715c~0.95x In the Goldilocks zone Under study LHS 1140 d~1.2x Marginal habitable zone Possible CO₂ and water vapor
Significance for planetary science and habitability.
The planets are all in the “habitable zone” – where temperatures are neither too hot nor too cold for liquid water to exist.
Some planets show signs of stable atmospheres, greenhouse gases, and possibly chemical traces of life such as methane, ozone, or water vapor.
NASA and ESA scientists plan to conduct intensive spectroscopic observations in 2025–2027. The goal is to confirm whether these planets could actually support life, or could potentially be habitable in the distant future.
