Summary edit

Description
English: This artist’s impression shows the planet K2-18b, it’s host star and an accompanying planet in this system. K2-18b is now the only super-Earth exoplanet known to host both water and temperatures that could support life. UCL researchers used archive data from 2016 and 2017 captured by the NASA/ESA Hubble Space Telescope and developed open-source algorithms to analyse the starlight filtered through K2-18b’s atmosphere. The results revealed the molecular signature of water vapour, also indicating the presence of hydrogen and helium in the planet’s atmosphere.
Русский: Художественное представление экзопланеты K2-18 b (справа), вращающейся вокруг звезды K2-18 (слева). В центре показана предполагаемая планета K2-18 c. K2-18b в настоящее время является единственной экзопланетой суперземли, на которой есть как вода, так и температура, которая может поддерживать жизнь.
Українська: Художнє зображення зоряної системи зірки K2-18 з екзопланетою K2-18b та супутньої планети. Наразі K2-18b — єдина суперземна екзопланета, на якій імовірно є вода, водень та гелій, а також температура, яка може підтримувати життя. Екзопланета K2-18b була відкрита у 2015 році за допомогою телескопа Кеплер і досліджена телескопом Габбл НАСА/ЄКА.
