The James Webb Space Telescope (JWST) is scheduled to take off next year and astronomers believe the super-powerful spier is experts' best hope to date of finding life beyond Earth.
The JWST is the successor to the Hubble Telescope and is much more powerful.
The successor will be able to see further into space, as well as more accurately measure the content of water, carbon dioxide and other components in the atmosphere of an exoplanet – a planet outside of our solar system – as well as tell scientists more about the size and distance these planets are from their host stars.
As a result, the giant telescope which sports a huge mirror to garner light, is being heralded as the best chance of finding alien life.
