Two Nearby Earth-Like Worlds Found in The Sweet Spot For Life to Survive : ScienceAlert.
In the search for life on other planets, a couple of promising leads have just opened up: Astronomers have identified two worlds with Earth-like masses, sitting in the habitable zone around a red dwarf star called GJ 1002.
The habitable zone around a star is the sweet spot between a planet being too hot or too cold to support life.
To be in this zone, planets must be orbiting their star at a distance where, theoretically, there could be liquid water on their surface.
“GJ 1002 is a red dwarf star, with barely one-eighth the mass of the Sun,” says astrophysicist Vera Maria Passenger from the Instituto de Astrofisica de Canarias (IAC) in Spain.
“It is quite a cool, faint star.
This means that its habitability zone is very close to the star.”

While we’re a long way from confirming alien life or even running water yet, GJ 1002b and GJ 1002c are ticking all the boxes so far – and at a mere 16 light-years away from our Solar System, they’re close to where we are in the Universe, astronomically speaking.

Up to a total of 5000 exoplanets planets Outside our Earth that have been Observed as telescopes and data Crunching algorithms get better we can Spot objects that are smaller and Further away from Earth thanks to these Improvements in technology we're getting Closer to being able to measure the Chemical signatures of Life on these Distant planets even though they're Light years away through space nature Seems bent on showing us that earth-like Planets are very common says Astrophysicist Alejandro Suarez Mascareno from ayak with these two we Now know seven in planetary systems Quite near to the Sun the research has Been published in astronomy and Astrophysics [Music]
