When #NASAWebb observed the Horsehead Nebula in infrared light earlier this year, it took this sharp image of the top of the horse’s “mane,” a distinctive dust and gas structure.

@kellylepo it's amazing to me how as you zoom in, entire galaxies suddenly appear in background! they were there all along, we just couldn't perceive them <3

@darkuncle Yes! One of my favorite things about JWST images are all of the background galaxies.

They show up because of:
• The telescope's large mirror which allows us to take high-resolution images and see faint things.
• The infrared wavelengths the telescope observes at, which allow us to see through most of the interstellar dust. Dust absorbs and scatters light at visible wavelengths.
