WEBB Is Fully Deployed!

The largest, most complex telescope ever launched into space is fully deployed.

Webb will be the premier observatory of the next decade, serving thousands of astronomers worldwide. It will study every phase in the history of our Universe, ranging from the first luminous glows after the Big Bang, to the formation of solar systems capable of supporting life on planets like Earth, to the evolution of our own Solar System.

Webb will continue to travel to the second Lagrange point (L2) for another two weeks, at which point it will enter a large orbit around the L2 point. The following five months will be used to cool the telescope to operating temperature, fine-tune the mirror alignment, and calibrate the instruments.
