Four distant galaxies in SMACS 0723. Left: the first JWST image with four galaxies highlighted. On the right, the four galaxies each seen with a different telescope or instrument. HST is the Hubble Space Telescope. JWST/NIRCam is the NIRCam instrument on the James Webb Space Telescope. JWST/MIRI is the MIRI instrument on the James Webb Space Telescope. A striking example is that galaxy ID 367 cannot be seen with Hubble. Credit: JWST/E. Iani & K. Caputi. |
