New image from the James Webb Space Telescope’s precision-guidance sensor

There are now a few days left until the first images and data of the file appear James Webb Space Telescope. The event will be held on July 12 starting at 16:30 (Italian time) on the channels social subordinate NASAAnd the European Space Agency and the Canadian Space Agency to show the world the potential of the new scientific instrument. From that moment on, a new chapter will open for the scientists working on the project who will have the opportunity to use JWST For a variety of research purposes.

New test image for a file Precision steering sensor (FGS). This tool was confirmed to be working properly in mid-February, and while it is not a part dedicated to scientific exploration per se, it remains essential to the correct management of the monitoring phases.

New FGS image of the James Webb Space Telescope

As you can guess from the name, the Precision steering sensor (FGS) is a sensor that allows space telescope In order to properly target the goals of different scientific campaigns that will follow each other at least five years from now. So we understand its importance in completing various notes.

The system is integrated inside James Webb Space TelescopeManufactured by CSA and allows for precise shooting. Everything depends on a system that obtains the images (which are usually deleted as “not useful” for the scientific part) and in particular the publication was taken in May.

The test involved the ability to aim and maintain the target for a long time (in this case eight days). It is said that it was a test intended to combine with Nircam subordinate James Webb Space Telescope The goal was there Star HD147980 The total exposure is 32 hours (with 72 single sessions).

It is interesting to note that although it is not a scientific image, this is the image that shows the most distant objects observed in the infrared (wavelength ranging from 0.6 μm to 5 μm). The sensor is monochromatic and color is added later in post-production. To interpret it correctly, it is necessary to consider that the lighter the element (white/yellow) the brighter it is, while the orange/red represents the weaker objects. On the right edge you can see the star 2MASS 16235798 + 2826079 with a magnitude of 9.3 while at the bottom you can see many galaxies. In the center of the brightest stars you can see a black dot indicating that the sensor has reached signal saturation.
