Mini-Neptune turned out to be a frozen super-Earth
Briefly

Exoplanet LHS 1140 b, initially thought to be a mini-Neptune, now considered a super-Earth near a cool red dwarf star, possibly capable of sustaining liquid water and being habitable.
Researchers find "tantalizing evidence for a [nitrogen]-dominated atmosphere on a habitable zone super-Earth," suggesting LHS 1140 b might have favorable conditions for life.
Observations of LHS 1140 b through NIRISS instrument allowed for transit spectroscopy, revealing insights about the exoplanet's atmosphere and potential habitability.
