We all know that, but now the James Webb Space Telescope (JWST) does, too.

The images update every minute, and you can expect action from 8:00 a.m. to 4:30 p.m. Eastern time Monday through Friday. Things slow down on the weekends, as the Webb and its associated engineers have to run errands and go to soccer games just like everybody else. You can check out all the action at
