![]() ![]() However, the habitable zone around a star where liquid water could theoretically exist-between the too distant “snow line” and the the too-close “boil zone”-doesn’t guarantee anything. She aded that the discovery of LP 890-9c is a unique opportunity to learn more about the exact position of the inner boundary of a star’s habitable zone. “LP 890-9c is located close to the inner boundary of the habitable zone and could therefore have an atmosphere that is particularly rich in water vapour, which would then boost its atmospheric signals," said Delrez. The study authors think this exoplanet could be ripe for a JWST atmosphere detection. This explains why LP 890-9c, despite being much closer to its star than the Earth is to the Sun, could still have conditions that are suitable for life.”īefore this “super-Earth” is declared even possibly Earth-like a lot more observations need to be made, specifically by the James Webb Space Telescope (JWST), which could help researchers examine its atmosphere-if it has one. ![]() “This is because the star LP 890-9 is about 6.5 times smaller than the Sun and has a surface temperature half that of our star. ![]() Pozuelos, researcher at the Institute of Astrophysics of Andalusia and one of the main co-authors of the paper. “Although this planet orbits very close to its star, at a distance about 10 times shorter than that of Mercury around our Sun, the amount of stellar irradiation it receives is still low, and could allow the presence of liquid water on the planet's surface, provided it has a sufficient atmosphere,” said Francisco J. ![]()
