Webb telescope in final destination
The James Webb Space Telescope has arrived at its cosmic parking spot a million miles away, bringing it a step closer to its mission to unravel the mysteries of the Universe, Nasa said Monday. At around 2:00 pm Eastern Time (1900 GMT), the observatory fired its thrusters for five minutes to reach the so-called second Lagrange point, or L2, where it will have access to nearly half the sky at any given moment. Webb will begin its science mission by summer, which includes using its high resolution infrared instruments to peer back in time 13.5 billion years to the first generation of galaxies that formed after the Big Bang. Webb, which is expected to cost NASA nearly $10 billion, is one of the most expensive scientific platforms ever built, comparable to the Large Hadron Collider at CERN, and its predecessor telescope, Hubble.
