I love this image of the SMACS galaxy cluster – there is so much going on in this one image! These tiny red shapes in the background are some of the oldest galaxies in the universe! You can also see the extraordinary gravitational lens! Now with bonus X-ray images from the Chandra Space Telescope! What part of the image do you think is the most amazing? #NASA #JWST #Chandra #Universe #Cosmology #Dark matter #Physics #Astronomy #Astrophysics
