View of 1st Start Through The Most Potential Telescope of The World
NASA announced Friday that the James Webb Space Telescope had its first star (but it was not quite tonight) and even picked a selfie.
The steps are parts of a months-long process of integrating the observatory’s massive golden mirror, which astronomers believe will reveal the secrets of the early Universe through this summer.
The first image of the cosmos beamed back isn’t particularly impressive: On a dark backdrop, 18 fuzzy white dots depict the same object: Within constellation Ursa Major, HD 84406 is a brilliant, lonely star.
It is, however, a significant milestone. The 18 dots were caught by the 18 distinct segments of the primary mirror, as well as the image is now being used to align and concentrate on those hexagonal parts.
The light rebounded off the sections and onto Webb’s secondary mirror, a circular object at the end of a very long boom, and Webb’s primary imaging gear, the Near Infrared Camera (NIRCam).
“The entire Webb team is ecstatic at how well the first steps of taking images and aligning the telescope are proceeding,” said principal investigator for the NIRCam instrument Marcia Rieke. “We were so happy to see that might make its way into NIRCam.”

On February 2, Webb began gathering images by pointing at several locations around the estimated location of the star.
Although Webb’s initial search spanned an area of the sky almost the size of a Full Moon, the dots all were clustered towards the center, indicating that the observatory is now in a great spot for final alignment.
To help in the procedure, the crew took a “selfie” using a customized lens onboard NIRCam rather than an externally placed camera.
NASA had previously stated that a selfie was not conceivable. Thus the revelation is a pleasant surprise for space enthusiasts.
The Universe’s expansion had extended the ultraviolet and visible light generated by the first bright objects, resulting in infrared, which Webb is designed to observe with unparalleled clarity.
Its goal also includes an examination of the evolution of distant planets, referred to as exoplanets, to identify their genesis and habitability.
