Two Exoplanets, Earth-Like Water Worlds Are Found, May Support Life

Dec, 2022 - by CMI

Researchers discovered two exoplanets in Montreal which are hundreds of light years away may be water made.

A research published in Astronomy & Astrophysicists puts light on the fact that astronomers tried to find out that life may occur outside Earth and in doing so they have discovered two worlds which seem to have Earth-like masses. They are known to have occupied a habitable zone, the sweetest spot between a planet not too cold or hot to support life, round a red dwarf star named Gj 1002.

As said by astrophysicist Vera Maria Passenger, from the Instituto de Astrofisica de Canarias (IAC) in Spain, “Gj is a red dwarf star, with barely one-eighth the mass of the Sun. It is quite a cool, faint star. This means that its habitability zone is very cool to the star.” The two exoplanets Gj 1002b and Gj 1002c is 16 light-years away from the Solar System. Star gazing instruments are used to spot the star and its planets. It is so used because the faint light that comes out of Gj 1002 needed instruments of high sensitivity and precision to understand its signatures.

Much is not about the celestial bodies. It takes 10 days to complete an orbit of Gj 1002b and is closest to star whereas Gj is further away and takes 20 days to complete an orbit. Their close proximity will enable to give a more detailed observation.  The following step will be to evaluate the atmosphere on the basis of the reflected amount of light and the amount of heat they emit.

About 5000 planets outside the earth, exoplanets, are under observation. With advanced data-crunching algorithms and better telescopes, in future, we will be able to spot the smaller objects that are very away from the earth. Due to advancements in technology, it helps in measuring the chemical signatures of the distant planets which are light years away from space.
