Telescope NASA TESS helped to find exoplanet that could contain liquid water
Exoplanet in the “Goldilocks zone”
TESS NASA telescope designed to search for exoplanets, has made a number of monumental discoveries discovering new worlds with impressive speed. At a scientific conference that is currently taking place at the Massachusetts Institute of technology, astronomers revealed on the three new extrasolar planets orbiting dwarf M-type, known as GJ 357. This is the nearest planetary system discovered by scientists, which could potentially be life.

One of the open planets particularly attracted the attention of scientists, because it is a super-earths with liquid water on the surface, and therefore there is a high probability of the existence of life. Potential twin of the Earth gave the name of GJ 357 d. Is this “water world” just 31 light-year away in the constellation Hydra. Furthermore, the exoplanet is in the Goldilocks zone of its star – the region suitable for life, where the temperature could support water in a liquid state. However, it is much closer to its star than Earth is to the Sun, and the year on it lasts only 55.7 per day.

“GJ 357 d located at the outer edge of the “habitable zones” where it receives approximately the same amount of heat as Mars from the Sun. If the planet’s thick atmosphere, it can hold enough heat to heat liquid water on its surface,” explains astronomer from the Institute of astrophysics max-Planck-Diana Kossakowski.

Astronomers will need more measurements to understand atmospheric composition of the planet, which could take years. So while one can only hope that the indirect signs of the presence on the planet GJ 357 d water confirmed the observations.
We will remind that earlier in the Universe discovered mysterious stars which burn helium and not hydrogen. And recently, the spacecraft NASA “bite off” a piece of the Sun.
