A team of Scientists has spotted a planet that has water and temperature similar to that of Earth. Now they are hoping that there are chances that this new planet could support life.
While analyzing data obtained through the Hubble telescope, the scientists observed a planet outside the solar system. Its size is similar to that of Earth. There are traces of water vapor in its atmosphere. As of now, the scientists have named this planet as K2-18b.
The newly discovered planet orbits an unknown star whose size is smaller to that of the Sun. The researchers have placed it in the group of ‘Habitable Zone.’ The planet is warm enough to store liquid water on its surface. Although similar in size, still the planet is approximately nine times as massive as that of the Earth.
K2-18b is 111 light-years away from our planet. After estimating its size, the scientists feel that it might be an icy giant like Neptune or it may have a rocky surface with an atmosphere having hydrogen gas in a massive amount.
The scientists had published there study regarding the new planet in a journal named www.arXiv.org during early September this year. They wrote that they had detected traces of water vapor in the new atmosphere of the new planet. Hence, this planet is a plausible candidate to search alien life. The planet orbits around a cool dwarf star in 33 days. It receives the same amount of radiation from its star as the Earth receives from the Sun.
Researchers studied the chemicals present in the atmosphere of newly discovered planets by observing changes at its starlight after planets start orbiting their respective parent stars. Once the planet has made a transit, its host star’s radiation falls on the atmosphere of K2-18b. The chemical compounds present in the atmosphere absorb the radiation at tale-tell frequencies.
