How do NASA scientists know where to point the camera from the James Web Telescope. If the camera is pointing one direction , what are we missing by not focusing on other areas?
Help me understand , because in my simple mind there’s space all around us & taking a picture usually only captures what in front of you .

Things in space still exist in some specific location, like specific stars. You’d face the thing you want to take an image of. You work that out by taking the position you see the object from earth, the position of the sun or some other reference points, and do some 3D trigonometry to work out where to face.
As for what you miss, it is like anything. If you take a photo of what is in front of you, you miss everything that isn’t in the direction you look.
What you miss totally depends on what you are not facing. There is “stuff” in all directions.
