TRAPPIST-1 :Seven Earth Like Exoplanets



NASA discovered seven Earth like planets at just 40 light years from Earth.


The seven planets orbiting the star TRAPPIST-1 are rocky and are Earth sized. From this 7 planets, three of the planets are situated in the habitable zone (Goldilocks zone). The chances of them having liquid water are extremely high.


Apart from this, these planets are extremely closer to one another. From a planets surface, you could easily see other TRAPPIST-1 planets in the sky.
NASA's James Webb Telescope launching in 2018 could detect the chemical fingerprints of water, methane and oxygen of potential atmospheres (key ingredients in assessing habitability)
