Description

The full color image of the combined public 361.3 hour Hubble Space Telescope + 52.7 hour James Webb Space Telescope Hubble Ultra Deep Field rendered in full panchromatic RGB. The 8 bluest HST-unique filters (WFC3/UVIS F225W, F275W, and F336W, ACS/WFC F435W, F606W, F775W, F814W and F850LP) were noise-weighted and rendered in blue, the JWST NIRCam SW filter images in green (F090W, F115W, F150W, F182M, F200W, F210M), and the JWST NIRCam LW filter images in red (F277W, F335M, F356W, F410M, F444W). At 414 hours, this is the deepest combined HST+JWST color image available to date, and demonstrates the strong complementarity of HST to JWST: HST adds the unique unobscured restframe UV+blue that samples the more recent half of the cosmic star-formation history in the last 10 billion years (redshift z≲2), compared to the JWST restframe optical–near-IR that samples older and/or more dusty stellar populations, and very rare objects at z≳10–13 seen in the first 300–500 million years since the Big Bang.
