Or then we have blurry image and a huge collective D'OH!"That star, called HD 84406, is located 241 light-years from Earth and part of the constellation Ursa Major, the Great Bear. The images will not be used for science, but will help the ground teams align the 18 golden segments of Webb's 21-foot-wide (6.5 meters) main mirror.
The images will be taken by Webb's Near Infrared Camera (NIRCam), which first has to cool down to its operational temperature of minus 244 degrees Fahrenheit (minus 153 degrees Celsius).
At the beginning, we will have 18 individual blurry images," Mark McCaughrean, a scientist at the JWST Science Working Group and senior advisor at the European Space Agency (ESA), who is familiar with the process, told Space.com . "At the end, we will have one nice sharp image."

On March 11, Webb completed "fine phasing," a critical stage that ensures Webb's optical capabilities are working how they should. During the tests, the team didn't encounter any issues and determined that Webb can observe light from distant objects and feed that light into the science instruments aboard the observatory.
What's the latest on the JWST? Will it radically transform our understanding of the universe, ourselves — Agent Smith
I daresay much of what is discovered will only really be comprehensible to specialists. — Wayfarer
JWST got through all 344 single-point failures - things that, if they had gone wrong, would have doomed the mission. So - so far it is going exactly as planned, astonishingly well, in fact.Will things go awfully wrong for the JWST or will it go as planned? — Agent Smith
