Spacestellar

NASA's James Webb Telescope set to launch in 2019 is the most powerful telescope ever made in the history of space exploration.It is believed to be the successor of the Hubble Space Telescope. But there's more...NASA calls James Webb telescope as a time machine! The James Webb telescope could see as far as 13.5 billion lightyears away.That is,it can see back 13.5 billion years back in time.It could see the formation of the first stars and galaxies in the universe after the big bang! The James Webb telescope could tell us more about the atmosphere of exoplanets,and maybe help us find life in other planets.The Trappist-1 planets would be the primary goal. JWST(James Webb Space Telescope) will see the universe in light invisible to human eyes. Though it seems primarily infrared light, it can also see red and gold visible light.

Enceladus is one of Saturn's icy moons and is yet another powerful candidate for the search for life beyond Earth. Enceladus has a vast liquid ocean underneath it's surface. This ocean water periodically erupts from Enceladus in the form of Geysers/Plumes . In October 2015, NASA's Cassini spacecraft made the deepest dive ever through a plume of gas and ice spraying from the south pole of Enceladus. The spacecraft "sniffed" the presence of Hydrogen. Hydrogen is like a "Candy" for microbes. They eat Hydrogen, then turn it into methane. So since Hydrogen in present at Enceladus, there may be a huge chance for microbes to exist. Not only this, the three primary ingredients for life has been confirmed at Enceladus. • Liquid Water • Source of energy • Right chemical ingredients So there actually might be a chance for Alien life to exist at Enceladus.

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)
