✨ Our NIRCam instrument's detectors have seen their 1st photons of starlight! This milestone is the first of many steps to capture engineering images that are at first unfocused, used to slowly fine-tune the optics. Similar to test shots in photography, the images taken by #NASAWebb during this period will not be “pretty” images like the new views of the universe Webb will unveil later this summer. They strictly serve the purpose of preparing the telescope for science. In our latest blog post, B

NASA Webb Telescope's golden mirror unveiled and flipped over. With glimmering gold surfaces, the large primary and rounded secondary mirror on this telescope are specially designed to reflect infrared light from some of the first stars ever born. The team will now begin to prepare to install the telescope's science instruments to the back of the mirrors.

How do we make a 21.3-foot mirror for our NASA Webb Telescope? We install 18 mirror segments together! With the first installation already complete, this marks the beginning of a critical phase of the observatory’s construction. The full installation is expected to be complete early in 2016.
