Nasa’s Kepler telescope discovers 2 habitable earth-like planets!

Recently more than 100 planets were discovered by an international team of scientist of NASA who used Kepler’s telescope.Among these planets according to NASA 2 planets have great potential to support life.A group total of 104 planets were found on this K2 mission.This mission was started back in 2009 and named as Kepler’s mission.

These 2 plantets form a solar system by orbiting a K2-72 star alongwith other two stars about 181 light years away.K2-72 is a dwarf star lying in the direction of Aquarius Contellation.The astronomers have already ruled out the other two stars as they are very near to the star and quite hot to support life.The size of star is much smaller than the Sun is host of only the four planets which orbit much closer if compared to mercury’s distance from Sun.

Dan Ruby,Director of Fleischmann Planetarium and Science Centre and University of Nevada,Reno talks about this discovery,’ So what’s exciting about these is that most of the planets we find outside of our solar system are big and gassy.A lot of them tend to be very close to their parent stars,so they tend to be really hot.Its very unusual to find planets that are small and at right distance from their parent star that they could be habitable’.

The planets are 20-40 percent larger than earth in diameter.They are supposed to be rocky and may have signs of water and thus life too as they lie in the habitable zone of their solar system.The habitable zone of this solar system is not much farther than the host star as the K2-72 is a dwarf star and does not possess much light and heat as compared to sun.

The two habitable planets:K2-72c and K2-72e differ from our earth in few aspects.The K2-72c is closer to the star and thus 10 percent warmer.On the other hand the K2-72e is 6 percent colder as it is a bit farther.15 days on earth equals 1 year on the K2-72c while the other’s 1 year is equal to 24 days on earth.

There are more further missions coming next year including The James Webb Telescope which would surely help in investigating a lot more useful information about these planets which will finally make sure if they really support life or not.
