This section of space often called "the eagle nebula" is 7000 light years from earth. As I understand it the only thing bright enough to form those shining lights from such a distance would be other stars! (This nebula is still in the milky way so as I understand it those bright lights shouldn't be other galaxies, as they'd be hidden by dust and closer stars.)

I don't know exactly how big of "a spot" this would be in the sky, but my gut tells me this entire image would only take up a chunk of the sky about the size of a small pebble held in your outstretched hand. Space is unfathomably big.

One of the first James Webb images of the deep field shows thousands of GALAXIES in a single image, as well as some stars in our own galaxy in the foreground. They aimed the telescope at a very dark section of the sky for many hours to actually capture enough light to produce the image!
