Nearly every light source in this deep field image is a galaxy.

No images capture the magnitude of space better than deep fields, or images of faint light across a swath of the night sky. The Dark Energy Camera imaged 10 deep fields several times, to capture faint light in the distant universe and better understand their distribution in three dimensions. The Webb Space Telescope has imaged a couple deep fields so far, and many more will come as astrophysicists try to glean more information about the early universe.
