For the first time in human history. A team of astronomers was finally successful in finding not one or two but seven Earth-sized planets that were revolving around a star and show high potential for life. And the best part is, this cluster of planet is located less than forty light years away in a constellation named Aquarius as was reported bb a Belgian-led research team and NASA. These planets have been circling tightly across a dim small star named Trappist-1 which is dimensionally size of the Jupiter. Three of these planets are in a habitable zone, the region close to the star where possibility of water as well as life is very high. The others are located right over the doorstep.
The team added that they need to observe and study its atmosphere before ascertaining whether these terrestrial, rocky planets are capable of supporting life or not. But it shows a positive side as multiple Earth-sized planets have been surviving on the sweet spot of the star and a perfect for extraterrestrial life. Higher the number of such planets better will be the chances of discovering a truly habitable planet for this purpose. Most habitable zone is the one that has a rocky surface.
One of the researchers, Amaury Triaud, from Cambridge adds, “We’ve made a crucial step toward finding if there is life out there. “It is a mind-boggling discovery which suggests better chances of our survival in space. Sara Seager from the Massachusetts Institute of Technology adds, “When there’s one, there’s more. With this amazing system, we know that there must be many more potentially life-bearing worlds out there just waiting to be found.” Another associate administrator from NASA, Thomas Zurbuchen, adds, “the discovery gives us a hint that finding a second Earth is not just a matter of if, but when,” and addresses the age-old question of “Are we alone out there?”
