A second earth has been discovered by a Greek scientist
After around 1.5 year of researching, a Greek astronomer Mr. Angelos Tsiaras( Graduate of the Aristotle University and doctor at UCL University of London) was led to this great discovery. It's the first time (at international level) water has been detected in gas form and in the atmosphere of a planet with temperature similar to earth's. Therefore these conditions are appropriate in order this planet to be habitable and livable. The water is either in liquid form in planet's surface or in its atmosphere.
It's about the exoplanet K2-18b which was discovered by the space telescope "Kepler" in 2015. It's possibly a rock hyper-earth with 8 times larger mass than earth's. It's regarded as the only planet which is around a star out of our solar system and there is so much water in its atmosphere and also with an appropriate temperature for life.
According to Mr. Tsiaras "K2-18b IS 2 steps ahead comparing to other 4.000 exoplanets that have been discovered regarding the possibility of life. Due to its exposition to the solar radiation this planet maybe is not friendly to earth". (source:ΑΠΕ-ΜΠΕ)
