NIRCam is designed to study the <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.jwst.nasa.gov\/content\/observatory\/instruments\/nircam.html\">faint infrared light produced by the oldest stars or galaxies<\/a> in the universe. But before it could do that, NIRCam had to help align the 18 individual segments of Webb\u2019s mirror.<\/p>\n<p>Once NIRCam cooled to minus 280 F, it was cold enough to start detecting light reflecting off of Webb\u2019s mirror segments and produce the telescope\u2019s first images. The NIRCam team was ecstatic when the first light image arrived. We were in business!<\/p>\n<p>These images showed that the mirror segments were <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/blogs.nasa.gov\/webb\/2022\/02\/11\/photons-received-webb-sees-its-first-star-18-times\/\">all pointing at a relatively small area of the sky<\/a>, and the alignment was much better than the worst-case scenarios we had planned for.<\/p>\n<p>Webb\u2019s Fine Guidance Sensor also went into operation at this time. This sensor helps keep the telescope pointing steadily at a target \u2013 much like image stabilization in consumer digital cameras. Using the star HD84800 as a reference point, my colleagues on the NIRCam team helped dial in the alignment of the mirror segments until it was virtually perfect, <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.nasa.gov\/press-release\/nasa-s-webb-reaches-alignment-milestone-optics-working-successfully\">far better than the minimum required for a successful mission<\/a>.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"3_What_sensors_came_alive_next\"><\/span>3.

This information can reveal the composition and temperature of distant stars and galaxies. NIRSpec does this by looking at its target object through a slit that keeps other light out.<\/p>\n<p>NIRSpec has multiple slits that allow it to <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/jwst-docs.stsci.edu\/jwst-near-infrared-spectrograph\/nirspec-instrumentation\/nirspec-fixed-slits\">look at 100 objects at once<\/a>. Team members began by testing the multiple targets mode, commanding the slits to open and close, and they confirmed that the slits were responding correctly to commands. Future steps will measure exactly where the slits are pointing and check that <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.stsci.edu\/jwst\/instrumentation\/instruments#section-8bc155d1-1325-4c34-b2c0-c1bb6524cdbd\">multiple targets can be observed simultaneously<\/a>.<\/p>\n<p>NIRISS is a slitless spectrograph that will also break light into its different wavelengths, but it is better at <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/blogs.nasa.gov\/webb\/2022\/06\/03\/the-modes-of-webbs-niriss\/\">observing all the objects in a field, not just ones on slits<\/a>.

What was the last instrument to turn on?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The final instrument to boot up on Webb was the Mid-Infrared Instrument, or MIRI. MIRI is designed to take photos of distant or newly formed galaxies as well as faint, small objects like asteroids. This sensor detects the longest wavelengths of Webb\u2019s instruments and must be kept at minus 449 F \u2013 just 11 degrees F above absolute zero. If it were any warmer, the detectors would pick up only the heat from the instrument itself, not the interesting objects out in space. MIRI has <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/jwst.nasa.gov\/content\/about\/innovations\/cryocooler.html\">its own cooling system<\/a>, which needed extra time to become fully operational before the instrument could be turned on.<\/p>\n<p>Radio astronomers have found hints that there are galaxies completely <a rel=\"nofollow noopener\" target=\"_blank\" href=\"http:\/\/www.sci-news.com\/astronomy\/alma-dust-obscured-galaxies-early-universe-10094.html\">hidden by dust and undetectable by telescopes like Hubble<\/a> that captures wavelengths of light similar to those visible to the human eye. The extremely cold temperatures allow MIRI to be incredibly sensitive to light in the mid-infrared range which can pass through dust more easily. When this sensitivity is combined with Webb\u2019s large mirror, it allows MIRI to <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/blogs.nasa.gov\/webb\/2022\/05\/09\/miris-sharper-view-hints-at-new-possibilities-for-science\/\">penetrate these dust clouds and reveal the stars and structures<\/a> in such galaxies for the first time.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"5_Whats_next_for_Webb\"><\/span>5.
