This image of a star with galaxies in the background was taken by the James Webb Space Telescope during its alignment process.
After James Webb Space Telescope officials released a stunning image of a single star, the team is ready to get other telescope parts in line with the observatory’s mirrors.
Webb should complete its commissioning period around June, six months after launching on Dec. 25 on an ambitious mission to observe the universe from deep space and gather data on objects ranging from exoplanets to galaxies. “All the cameras see the sky at the same time; to switch a target from one camera to another, we repoint the telescope to put the target into the field of view of the other instrument,” Gardner wrote.
FGS reached its own milestone recently, which was finishing “fine guide mode.” That occurs when the guider zeroes in on a guide star to the instrument’s highest possible precision. Additionally, engineers are taking “dark” images to see what happens when the instrument has no light reaching it, which allows personnel to more precisely calibrate the instrument.
