Researchers at the Harvard Smithsonian centre for Astrophysics discovered that the planet GJ1214b was largely covered in water. They used Hubble Space Telescope to discover the water on planet. GJ1214b was discovered in 2009 by the ground-based MEarth Project. GJ1214b was described as a super-Earth. It is approximately 2.7 times Earth’s diameter and weighs almost 7 times as much.
This presence of water on the planet was confirmed when it crossed in front of its host star. The light of the star, filtered through the planet’s atmosphere, provided clues to the mix of gasses, supporting the water vapor theory.
