The James Webb Space Telescope is fully aligned and ready to observe the universe

The James Webb Space Telescope is ready to observe the universe.

The space observatory's massive mirror, capable of peering into the most distant reaches of space, is now completely aligned, according to the NASA's Webb team.

Hailed as the world's premier space observatory, Webb has successfully completed a number of steps within the past few months that were crucial for aligning its 18 gold mirror segments.

The mirror is so large that it had to be folded to fit inside the rocket for its December 25 launch. After reaching an orbit a million miles from Earth in January, Webb began the careful process of unfolding and aligning its mirror.

Webb will be able to peer inside the atmospheres of exoplanets and observe some of the first galaxies created after the universe began by observing them through infrared light, which is invisible to the human eye.
