       #JWST keeps getting us amazing new observations. Linked here is the famous "Cartwheel" #galaxy in a combined NIRCam and MIRI image. NIRCam shows the smooth older star population, while MIRI (red) shows regions rich on dust and molecular gas. Also note the two background galaxies. They are approximately the same distance and size, yet the difference in MIRI is striking. #Webb #Science #Astronomy #Astrophysics https://www.nasa.gov/feature/goddard/2022/webb-captures-stellar-gymnastics-in-the-cartwheel-galaxy

       For comparison, here is what the Cartwheel #galaxy looked like when observed by #Hubble a decade and a half ago. The contrast between the smooth, older star population in the center and the frenzied star formation in the outer ring is even more striking here, as is the difference between the two background spirals in the upper left. #Astronomy #Astrophysics #Science https://www.nasa.gov/image-feature/goddard/2018/hubble-s-cartwheel

       Notice also the difference in the number and brightness of background galaxies between the #Hubble and the #JWST observations! It's true what they said - with #JWST, every field is a deep field - there are no more "blank" patches of sky.
