Webb in full focus

The adjustment of the Webb Telescope's (JWST) mirrors and instruments is now complete. This means that the telescope can take images in optimal sharpness with all cameras, which is demonstrated in the image that NASA has released. The telescope is now ready to begin the final preparations before it can be used by avid astronomers. In this final step, each instrument will be tested in all possible modes to ensure that it is ready for the scientific observations.
