About 111 light-years from Earth in the Leo constellation is exoplanet K2-18b.

The planet was originally discovered in 2015, but researchers now begin to believe that the world is very similar to ours, but more than double the size, putting it in the category of Super-Earths.

The original observations suggest that the planet orbits in the habitable zone of its host star, a region where it is neither too hot nor too cold where conditions are adequate to sustain life.

The observations made in Planet Searcher of high precision with radial velocity (HARPS), an 11.8-foot telescope at the La Silla Observatory of the European Southern Observatory in Chile, suggest that the planet, which is 2.2 times more larger than ours, is a rocky world with a thin atmosphere, like Earth, or a world of water covered with a layer of ice.

Study lead author Ryan Cloutier, a Ph.D. A student at the University of Toronto and the Institute of Exoplanet Research at the University of Montreal, said: "With the current data, we can not distinguish between these two possibilities.

" But with the James Webb Space Telescope, we can investigate the atmosphere and see if it has a vast atmosphere or is a planet covered in water. "

The James Webb Space Telescope (JWST) is so powerful that it will make the Hubble Telescope look like a pair of binoculars, fans say. [19659002] The infrared machine is so powerful that it will reach the most distant realms and the first moments The JWST has the ability to explore thousands of planets for extraterrestrial life, even though those planets are thousands of light-years away.

The JWST is scheduled to be operational next year, but the delays in the integration of key instruments, such as the 6.5-meter mirror that will help you see in deep space, have delayed the launch until March or June 2019.

The co-author of the study, René Doyon, said: "K2-18b is now one of the best targets for atmospheric study, it is reaching the top of the list."
