If we ask ourselves whether all instruments can see the sky at the same time, can we use them simultaneously? The answer is yes! With parallel scientific exhibitions, when we point an instrument to a target, we can read another instrument at the same time, NASA experts say. To herald the completion of the alignment of Webb’s 18 gold mirrors, used to capture light from. Parallel data allows scientists to determine the statistical properties of the galaxies that are detected,” Gardner concluded. The James Webb Space Telescope (JWST) is now fully aligned, and NASA has the pictures to prove it. Parallel observations don't see the same point in the sky, so they provide what is essentially a random sample of the universe. “ With parallel scientific exhibitions, when we point an instrument to a target, we can read another instrument at the same time. Gardner also explained how instruments will work together to observe a goal. The final stages of MIMF will align the telescope for MIRI. Interspersed with the initial observations of MIMF, the two stages of the cooler will be switched on to bring MIRI to its operating temperature. Webb will solve mysteries in our solar system, look beyond to distant worlds around other stars, and probe the mysterious structures and origins of our universe and our place in it. The last instrument to be aligned will be the Mid-Infrared Instrument (MIRI), as it is waiting for the ability of a cryogenic cooler to bring it to its operating temperature of minus 448 degrees Fahrenheit (minus 267 degrees Celsius). The James Webb Space Telescope is the world’s premier space science observatory. The goal of the new lineup, Gardner said, is to “provide good focus and sharp images on all instruments” while knowing the relative positions of each instrument's field of view. We have also been taking dark images to measure the response of the reference detector when light does not reach them, an important part of the instrument calibration,” added the expert. At another milestone of the instrument, FGS recently achieved fine guidance mode for the first time, blocking a guiding star using its highest level of accuracy. Over the past weekend, we mapped the positions of the three near-infrared instruments relative to the guide and updated their positions in the software we used to point the telescope. “In addition, we need to know precisely the relative positions of all fields of view. After MIMF, Webb's telescope will provide good focus and sharp images on all instruments,” explained Jonathan Gardner, deputy principal scientist for the Webb project at NASA's Goddard Space Flight Center in Maryland. To change a lens from one camera to another, astronomers point the telescope to place the lens in the other instrument's field of view. “ In space telescopes like Webb, all cameras see the sky at the same time.
