The James Webb Space Telescope is all set to launch in 2018, it will be a Mega-telescope that has the potential to reveal atmospheres in the new found worlds. The seven earth sized planets could possibly support water on their surface, and the JWS Mega-telescope is sensitive enough to identify the chemical components of the atmospheres present on the planets.
This upcoming Mega-telescope will be the key to unlocking secrets of the seven planets; it will determine if these planets have atmospheres and other components. NASA also has other missions at this moment like the Hubble, Kepler and Spitzer telescopes, at present these telescopes are following up on the new found planets as per Space.
Researchers were already aware of planets orbiting the faint star TRAPPIST-1, in was in 2016 that they discovered three planets in the star's orbit. Recently NASA's Spitzer Space Telescope confirmed that there are seven planets. The most mysterious fact is that three of these planets could potentially have an Earth style life, scientists believe that the orbits keep the three planets at the right temperature.
If they have atmospheres then they could also have liquid water on their surfaces, the JWS Meg-telescope will be the one to confirm this possibility once it is launched. NASA's Spitzer telescope had a benefit in looking at the TRAPPIST-1, this is because the star is an ultra cool dwarf and much brighter in infrared than in visible light.
Spitzer was able to observe each of the planets while they passed the star, this helped researcher to work out their sizes and estimate their densities. Some of the results suggested that the planets could be rocky like Earth. It is left up to the upcoming Mega-telescope to reveal atmospheres in the new found worlds. Until then researchers will continue to gain more knowledge on the discovered planets.
