Webb telescope spots super old, massive galaxies that shouldn’t exist

Feb. 22, 2023

In a new study, CU Boulder astrophysicist Erica Nelson and her colleagues spotted six "fuzzy dots" of light in images from the James Webb Space Telescope. The candidate galaxies may have existed just 500 to 700 million years after the Big Bang and contain almost as many stars as the Milky Way.
