Euclid’s first science images reveal what JWST cannot

among other aspects. While telescopes like Hubble and JWST have captured our imaginations with their deep, high-resolution views all across the Universe, they also face a tremendous limitation: they have narrow, small-angle fields of view, and can only see a tiny fraction of the sky at once. But other observatories — although they’re usually smaller, lower in resolution, and cover narrower sets of wavelength ranges — have the advantage of being able to image large areas of the sky all at once. While <a href="https://roman.gsfc.nasa.gov/" rel="noopener ugc nofollow" target="_blank">NASA’s upcoming Nancy Grace Roman Space Telescope</a> and the <a href="https://rubinobservatory.org/" rel="noopener ugc nofollow" target="_blank">NSF’s Vera Rubin observatory</a> will excel in those regards, the <a href="https://en.wikipedia.org/wiki/Euclid_(spacecraft)" rel="noopener ugc nofollow" target="_blank">ESA’s Euclid mission</a> has gotten there first: having launched in July of 2023 and now, in November, begins its 6+ year mission to map out as much of the Universe as possible. It’s a remarkable and ambitious project, and not only <a href="https://www.esa.int/Science_Exploration/Space_Science/Euclid/Euclid_s_first_images_the_dazzling_edge_of_darkness" rel="noopener ugc nofollow" target="_blank">are its science operations already underway</a>, but it’s going to revolutionize what we know about the Universe. Here’s how. <a href="https://medium.com/starts-with-a-bang/euclids-first-science-images-reveal-what-jwst-cannot-1f3808e5d695">Website</a>
