Detailed explanation-1: -NASA’s Hubble Finds Water Vapor on Habitable-Zone Exoplanet for 1st Time. This artist’s impression shows the planet K2-18b, its 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.

Detailed explanation-2: -A team led by researchers at the University of Montreal has found evidence that two exoplanets orbiting a red dwarf star are “water worlds,” where water makes up a large fraction of the entire planet.

Detailed explanation-3: -Astronomers have finally uncovered water vapor in the atmosphere of a super-Earth exoplanet orbiting within the habitable zone of its star. The find means that liquid water could also exist on the rocky world’s surface, potentially even forming a global ocean.

Detailed explanation-4: -It is possible that clouds form and even rain falls on this faraway world, dubbed K2-18 b. The planet lies within what astronomers call the habitable zone, with a temperature that could allow life to thrive there. The rocky planet is eight times the mass of Earth and known as a super-Earth.

Detailed explanation-5: -Piaulet and colleagues observed exoplanets Kepler-138 c and Kepler-138 d with NASA’s Hubble and the retired Spitzer space telescopes and discovered that the planets could be composed largely of water.
