Neighbours in space!!

Don’t know if its exciting or scary for you but this is really cool. National Aeronautics and Space Administration on 22nd feb, wednesday had a major announcement to make and it came out as a real cool news! NASA along with its partner all around the worlds has found a solar system with 7 earth alike planets revolving around a small star (Trappist1) just 39 light years away! As per Michael Gillon, the lead author of the ‘Nature Paper’ announcing the discovery, “it would be the first time that so many planets with as similar feature as earth has been found in a single solar system”. Not only this, three among these seven planets are at the star habitable zone, that means that its most  likely that these planets would have the existence of water on their surface. One of them has a mass indicating a water rich composition. the distance at which these planets orbits the star can be compared with the Jupitar and its moons.  Also, these planets lies at the zone where their temprature is estimated to be in between zero to hundred degree C.

These worlds have sizes and temperatures similar to those of Venus and Earth and are the best targets found so far for the search for life outside the Solar System. They are the first planets ever discovered around such a tiny and dim star.

Right now, the astronomers are beginning to study the planets’ atmospheres with the telescopes they have. And from these observations, they feel fairly confident that the worlds are rocky. “For detailed characterization, we will need James Webb,” Triaud said.

“With this discovery we’ve made a giant, accelerated leap forward in our search for habitable worlds and life on other worlds potentially,” Sara Seager, a leading exoplanet expert at MIT, said during the announcement. This one star system, she said, gives astronomers many chances to look for life, and refine their understanding of exoplanets in small-star systems.

Today Google’s doodle  recognized the event too.

WE always has assumed about the life over other planets but this time its indeed a huge discovery.

As NASA associate administrator Thomas Zurbuchen said, “Finding another Earth-like planet isn’t a matter of if but when.” 

whats your take on this exciting discovery? please leave a comment 🙂
