NASA completes construction of World's Largest Space Telescope

The National Aeronautics and Space Administration (NASA) on 2 November 2016 completed the construction of the James Webb Space Telescope (JWST) after more than 20 years of hard work.
●    This largest-ever space telescope is expected to launch in 2018 following the in-depth testing.
●    The telescope has 18 large mirrors that will collect infrared light, sheltered behind a tennis-court-size sun shield. 
●    It is considered as the successor to NASA's iconic Hubble Space Telescope.
●    It is a 8.8 billion US dollars worth space observatory built to observe the infrared universe like never before.
●    The telescope's infrared view will pierce through obscuring cosmic dust to reveal the universe's first galaxies and spy on newly forming planetary systems. 
●    It will also be sensitive enough to analyze the atmospheres of exoplanets that pass in front of their stars, perhaps to search for signs of life.
