US space giant NASA has said that it has discovered as many as 7 habitable planets, almost the size of our planet Earth. The space agency said that the planets are orbiting a giant star and there are chances that the newly discovered planets may support life or even have alien life.
NASA has said that the earth sized planets that it has discovered actually circle around a dim dwarf star called Trappist-1. NASA astronomers have said that the size of the dwarf star in question is rather very small. It is barely the size of Jupiter.
This is apparently first time when so many habitable planets have been discovered in one go. Though, a few such planets have been discovered in the past, these were just one or two. NASA scientists claim that the seven planets are less than 40 light-years away in the constellation Aquarius. NASA and the Belgian-led research team who announced the discovery Wednesday.
Nonetheless these planets’ being habitable is not final as scientists have said they need to study the atmospheres before determining whether these rocky, terrestrial planets could support some sort of life. But it already shows just how many Earth-size planets could be out there _ especially in a star’s sweet spot, ripe for extraterrestrial life.
University of Cambridge’s Amaury Triaud, while talking about the latest development said, “we’ve made a crucial step toward finding if there is life out there”.
The finding of the planet orbiting this star began sometimes ago. University of Liege’s Michael Gillon says, “There are 200 billion stars in our galaxy,” said co-author Emmanuel Jehin of the University of Liege. So do an account. You multiply this by 10, and you have the number of Earth-size planets in the galaxy _ which is a lot”. This compact solar system is reminiscent of Jupiter and its Galilean moons, according to the researchers. Picture this: If Trappist-1 were our sun, all seven planets would be inside Mercury’s orbit. Mercury is the innermost planet of our own solar system.
