US top space agency NASA has said that it has discovered as many as seven habitable planets of the size of planet earth. Though there have been reports of habitable planets being found by the NASA, it is the first time that more than a dozen such planets have been discovered by NASA in one go.
Many people have claimed for a long time, that as the Earth becomes overpopulated and its resources get depleted, humans may have to migrate to other Earth like planets to survive and prosper.
This is notwithstanding the fact that despite all the enthusiasm from scientists, they still can’t be sure of either the size of the planets that are billions of miles away from Earth, let alone being hospitable that can sustain life. Despite, all the enthusiasm among the scientific community, they still haven’t been able to devise a method to measure the distance between earth and other planets outside our solar system.
Reports suggest that this cluster of planets is less than 40 light-years away in the constellation Aquarius, according to Nasa and the Belgian-led research team who announced the discovery Wednesday.
NASA scientists have said that planets circle tightly around a dim dwarf star called Trappist-1, barely the size of Jupiter. Three are in the so-called habitable zone, where liquid water and, possibly life, might exist. The others are right on the doorstep. Scientists 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 detailing the finding said, “we’ve made a crucial step toward finding if there is life out there”. Triaud went on to add that the prospects of more Earth-size planets in our Milky Way galaxy is mind-boggling.
Scientists associated with the research said that star at the heart of this system would shine 200 times dimmer than our sun, a perpetual twilight as we know it. And the star would glow red — maybe salmon-colored, the researchers speculate. “The spectacle would be beautiful because every now and then, you would see another planet, maybe about as big as twice the moon in the sky, depending on which planet you’re on and which planet you look at,” Triaud said Tuesday in a teleconference with reporters.
