For the first time, astronomers have discovered seven Earth like planets orbiting a single nearby star — and these new worlds could hold life.
According to NASA and the Belgian-led research team who announced the discovery, these planets are nearly 40 light-years away. These planets revolve around a star called Trappist-1 which is barely the size of Jupiter. Though more research needs to be done on those planets atmosphere, which current data in hand, scientists believe that three of these planets could be habitable as they probably might have water. Scientists proclaim that these rocky planets could also support some kind of life form as per their atmospheric conditions.
This is one such discovery which strongly establishes the hope of finding habitable terrestrial planets among those dark skies and supports the beliefs of many that ‘we are not alone’ in this universe.
Amaury Triaud, one of the researchers from the University of Cambridge’s said that, “We’ve made a crucial step toward finding if there is life out there,”
Few months back, the University of Liege’s Michael Gillon and his team reported finding three planets around Trappist-1. Now the count has gone up to seven, and there could be more. Their latest findings appear in the journal Nature.
Researchers believe that the Trappist-1 is a very dim star, probably 200 times dimmer than our sun and all seven planets would only be as far as Mercury’s orbit in our solar system. Due to these smaller orbits, these planets are expected to have very short years ranging between 1 to 20 days to orbit around their Sun,Trappist-1
