JWST/MIRI is cold and focused!
The James Webb Space Telescope launched on December 25, 2021 and is undergoing its commissioning phase.
The observatory has reached a big milestone with the telescope aligned and all science instruments cold and ready to obtain calibration data. MIRI, the coldest of the four instruments, reached its operating temperature of 7 K and took its first images. In the figure a comparison of the same field in the LMC is shown from different space observatories at similar wavelengths. The amazing resolution that the 6.8 m primary mirror of Webb provides can be seen in the MIRI image on the right, where details of the dust, background stars and galaxies come in focus.
