(This message was added in version 6.7.0.) in /home4/scienrds/scienceandnerds/wp-includes/functions.php on line 6114Source: https:\/\/www.theverge.com\/2022\/2\/11\/22929054\/nasa-james-webb-space-telescope-first-images<\/a> NASA unveiled a mosaic of the first images<\/a> captured by the revolutionary James Webb Space Telescope, or JWST, today. The image represents the early stages of the telescope\u2019s 18 main mirror segments properly aligning before JWST reaches its full potential. <\/p>\n The image is blurry, but this is actually a good starting point in the long process of adjusting JWST\u2019s mirrors to take ultra-sharp photos of the distant Universe. The 18 points of light that appear in the image all represent the same isolated star, known as HD 84406, seen by a different primary mirror segment. Light collected from each primary mirror segment was reflected back to Webb\u2019s secondary mirror, then measured using one of the telescope\u2019s key imaging instruments, the Near Infrared Camera, or NIRCam. This sensor will be used throughout the telescope\u2019s alignment process to determine and correct any optical errors. <\/p>\n The process of collecting the light used to generate the image mosaic took about 25 hours, according to NASA. The 18 images of HD 84406 were pieced together from more than 1,500 images collected as Webb was pointed to various positions around the expected location of the star. The mirror will begin to align correctly following the various adjustments<\/a> that the telescope will make over the coming months. Ultimately, those 18 stars will become one as all of the mirror segments are aligned to create a seamless surface. <\/p>\n
