NASA‘s Hubble Space Telescope has discovered water vapor in the atmosphere of a distant Earth-like exoplanet called K2-18b.

The earth lies about 110 light-years away in the Leo constellation, according to a press release from NASA about the exoplanet. NASA states K2-18b resides in a “habitable area,” which is “the region around a celebrity in which fluid water could pool externally of a rocky planet.”

The analyses from the Hubble Space Telescope likewise suggest that hydrogen, as well as helium, can be present in the environment of the exoplanet.

While the exoplanet is greater in size and has a lot more gravity as well as radiation than Planet, NASA stated it’s the only exoplanet they have discovered so far to have water in its environment as well as temperatures that could sustain life as well as sustain liquid stream on a rocky surface. The world may be habitable.

K2-18b was initially found in 2015 as well as is just one of the numerous what NASA calls “Super-Earths.” NASA stated that its planet-hunting satellite, called TESS (Transiting Exoplanet Survey Satellite), is anticipated to find hundreds even more of these Super-Earths in the following few years.

TESS found its first exoplanet back in March with the discovery of the planet TOI 197.01. The earth is about the size of Saturn; however lies a lot closer to its celebrity than we are to the Sun, suggesting it has very high surface temperatures.

Various other crucial exoplanet explorations include DS Tuc Abdominal, which was recognized by TESS in July. Astronauts are currently studying the exoplanet to understand more about just how earth expand and also establish. There’s additionally a massive concentrate on habitability– which planets could (in theory) sustain human life.

On the whole, TESS has been able to find greater than 20 different piles of the earth during its very first year of monitorings, including several planets that are unlike the ones found below in our planetary system.

NASA has verified the existence of greater than 4,000 planets outside our solar system. The sheer variety of that goes over, however even more so if you consider that before 1992, we could not discover any exoplanets.

Digital Trends reached out to NASA for more info on K2-18b, and its relevance precede study, and also will certainly upgrade this story if we hear back.
