The James Webb Space Telescope team clears the first instrument

Six months after the observatory was launched into space, an exoplanet hunter and first light detector on NASA’s next-generation space telescope is ready to do science.

The $10 billion James Webb Space Telescope is completing commissioning by testing its four state-of-the-art instruments and their various modes, which will allow Webb to study distant galaxies as well as closer objects in the Milky Way or the Solar System.
