Scientists have discovered water vapour on a little-known exoplanet known as K2-18b located 110 lightyears away. Given its larger mass, the surface gravity of K2-18b exoplanet is much higher than that of the Earth.
The new star system, called TESS Object of Interest, or TOI-270, is exactly what the Transiting Exoplanet Survey Satellite, or TESS, was designed to find, said researchers from the University of California, Riverside in the US.
The exoplanet, described in the journal Monthly Notices of the Royal Astronomical Society, has a mass of 20 Earth masses, a radius 20 per cent smaller than Neptune, and temperature of 1000 degrees Celsius.
Scientists from Italy's National Institute for Astrophysics (INAF) and University of Bristol in the UK spent three years observing the exoplanetary system Kepler-107 via the Telescopio Nazionale Galileo in La Palma.
Using the Atacama Large Millimeter Array, or ALMA, comprising 45 radio antennas in Chile's Atacama Desert, the team performed a survey of young stars in the Taurus star-forming region, a vast cloud of gas and dust located a modest 450 light-years from Earth.
NASA announced a new system of Exoplanets, which are Earth-size, and could potentially hold life.These exoplanets are located outside of our solar system and orbit a star, which is why they are named so. So why is the discovery of these Exoplanets such a big deal, and what should you know about them? We break […]
