Key Takeaways:

  • The James Webb Space Telescope (JWST) has successfully reached its final destination, the second sun-Earth Lagrange point (L2), about 1 million miles from Earth, after a month-long journey.
  • Its orbit at L2 allows it to observe the universe without interference, with its primary mission being to peer into the moments shortly after the Big Bang.
  • Before it can begin taking images, which is anticipated by summer, the telescope's mirrors require precise alignment and its instruments need to cool down to extremely low operating temperatures.

The long-awaited James Webb Space Telescope has reached its final destination after a month-long journey, 1 million miles away from Earth, to peer into the moments shortly after the Big Bang.

Monday afternoon, Webb fired its onboard thrusters for nearly five minutes to perform its final course correction to its orbit around the second sun-Earth Lagrange point, known as L2.
