I checked outside...It's raining here in the desert...so I can't tell

Could be a calibration image.
Other missions use stars for navigation/positioning purposes..Could be that as well..

Sorry space, but I don't understand what you are saying.

Could be a calibration image.

I don't understand what any of that means.

no problem.

Like ancient navigators.
Nasa uses stars, to tell the orientation, and direction
of a spacecraft...Take a picture of a pattern of stars, and you immeditately know
which way your spacecraft is pointing..

FOr calibration: you may want to take a picture of "nothing" every once in a while...This will tell you how well your camera is working, if any pixels are damaged, etc......That way, if you see what you think is a spot on the Sun, you can discount it, knowing that you are actually looking at a bad pixel...

I noticed in the image that you linked, that there were some stars in it...
