The Ultra Deep Field, in the eyes of #Hubble and #Webb 👁️👁️ This famous view of nearly 10,000 galaxies – of various ages, sizes, shapes, and colours – is called the Hubble Ultra Deep Field. The smallest, reddest galaxies in the image are among the most distant known, existing when the Universe was just 800 million years old. The stunning image required 800 exposures taken over the course of 400 NASA/ESA Hubble Space Telescope orbits around Earth in 2003 and 2004. Almost 20 years later, the NASA/ESA/CSA James Webb Space Telescope’s #NIRCam observed the Ultra Deep Field. It did so at depths comparable to Hubble, revealing galaxies of similar faintness, in just one-tenth as much observing time. 📷 nasa , europeanspaceagency, and S.
