If you haven't, then read the part 1 here : Gravitational Lensing Part 1
The concept of Gravitational Lensing is relatively new and is now set to be used to find and unveil the bigger mysteries of the big bang and the first light of the universe.
NASA's James Webb Space Telescope is scheduled for launch in 2021. It will probe the cosmos to uncover the history of the universe from the Big Bang to formation of planets and what lies beyond our Milky way galaxy. It will focus on four main areas :
First light in the universe,
Assembly of galaxies in the early universe,
Birth of stars and protoplanetary systems and,
Planets capable of supporting life (including origins of life forms).
The James Webb Space Telescope (JWST) will launch on an Ariane 5 rocket from French Guiana, then take 30 days to fly a million miles to its permanent home: a Lagrange point, or a gravitationally stable location in space. It will orbit around L2, a spot in space near Earth that lies opposite from the sun. This has been a popular spot for several other space telescopes, including the Herschel Space Telescope and the Planck Space Observatory.
The powerful $8.8 billion spacecraft is also expected to take amazing photos of celestial objects like its predecessor, the Hubble Space Telescope. Luckily for astronomers, the Hubble Space Telescope remains in good condition and it's probable that these two telescopes will work together for JWST's first years. JWST will also look at exoplanets that the Kepler Space telescope found. It will also follow up on real-time observations from ground space telescopes.

P.S
This Telescope will be used to recognize the light deflected due to large celestial bodies having high gravitational potential as described in Gravitational Lensing Part 1
