Stunning images from the James Webb Space Telescope continue to entrance, and recently the researchers using the telescope have shared a gorgeous image of a field of galaxies as part of the Webb Picture of the Month collection.
The data for this image were collected as part of the calibration process for some of Webb’s instruments. Although instruments used in space-based telescopes are calibrated as exactly as possible while they are still on the ground, it is still necessary to perform some more refinement once the telescope is launched and is in its final orbit. In the case of Webb, its instruments continued to be calibrated for several months after its launch.
“This particular observation was part of the commissioning campaign for Webb’s Near-InfraRed Imager and Slitless Spectrograph ,” the European Space Agency writes. “As well as performing science in its own right, NIRISS supports parallel observations with Webb’s Near-InfraRed Camera . NIRCam captured this galaxy-studded image while NIRISS was observing the white dwarf WD1657+343, a well-studied star.
