![]() You can notice that the two images depict different stars. At the same time, we also see a lot of complex intertwining structures that are invisible in the Hubble photo, which complement the spiral arms of IC 5332. Therefore, the dust areas in the JWST image are not dark at all. At the same time, the dust transmits infrared radiation. It absorbs visible light, which is why dusty areas look dark. In the Hubble photo, you can see a lot of dark areas in the galactic disk. Lee and the PHANGS-JWST and PHANGS-HST Teams For a more visual demonstration, it should be compared with the image taken by the Hubble Space Telescope in the visible and ultraviolet range.Īn image of the galaxy IC 5332 taken by the James Webb Telescope. The JWST image of the galaxy IC 5332 demonstrates some of the possibilities of shooting in the mid-infrared range. It cools MIRI to a record temperature of -266 ☌, allowing it to conduct observations. ![]() The only way out is to install an active cooling system capable of cooling the instrument sensors to a temperature close to absolute zero. Putting a telescope into space is not a panacea in itself, because the heat it emits will simply “make noise” the entire channel. Radiation at these wavelengths is almost completely absorbed by the Earth’s atmosphere. The mid-infrared range is extremely difficult to observe. It was obtained using the MIRI instrument, capable of taking pictures in the mid-infrared range at wavelengths from 5 to 28 microns. The image taken by JWST demonstrates unprecedented details of the internal structure of IC 5332, which are beyond the power of any other telescope. Lee and the PHANGS-JWST and PHANGS-HST Teams Difficulties of taking pictures in the mid-infrared range An image of the galaxy IC 5332 taken by the James Webb telescope. This object is located at a distance of 29 million light-years from Earth in the direction of the constellation Sculptor. It demonstrates the spiral galaxy IC 5332. The presented image was taken by the James Webb Space Telescope (JWST).
