Scientists discover water vapor in atmosphere of a super-Earth “K2-18b”

For the first time, the astronomers at the University College London have discovered water vapour in the atmosphere of an Earth-size planet called K2-18b. They used data from NASA’s Hubble Space Telescope. The exoplanet “K2-18b” is 8-times the mass of Earth and known as a super-Earth. It orbits a red dwarf star 110 light-years away ..

Scientists discover new Saturn like planet 60 times bigger than Earth

Astronomers have discovered a new exoplanet using NASA’s exoplanet-hunting space telescope, TESS. The exoplanet is said to be 60 times bigger than our planet and is five-billion-year-old planet. The exoplanet is dubbed TOI-197.0 or “hot Saturn” because of its size and hot temperature. The researchers at Aarhus University, say that this is “one of the ..

Researchers discover a “super-Earth” type planet – GJ 536 b

Scientists have discovered a “super-Earth” type planet, GJ 536 b, in orbit around a nearby very bright star. The exoplanet has a mass of around 5.4 Earth masses and is not within the star’s habitable zone. It is orbiting a star much smaller and cooler than the sun. The planet’s short orbital period of 8.7 ..
