Jun 13, 2023 · The James Webb Space Telescope has captured the light from the earliest galaxies and quasars in the cosmic history. Learn how astronomers are using JWST to study the formation and evolution of supermassive black holes and massive galaxies in the first billion years of the universe.
In astronomy, first light is the first use of a telescope (or, in general, a new instrument) to take an astronomical image after it has been constructed. This is often not the first viewing using the telescope; optical tests will probably have been performed to adjust the components.
Jun 22, 2023 · New results from the James Webb Space Telescope find that radiation from ordinary galaxies cleared the primordial haze left over from the Big Bang, allowing the first light to shine through the early universe. There are more than 20,000 galaxies in this field, which lies between the Pisces and Andromeda constellations.
Jun 13, 2023 · Learn how NASA’s James Webb Space Telescope (JWST) has revealed surprising discoveries about the earliest galaxies and black holes in the cosmic history. Find out what astronomers have learned from JWST’s first year of observations and what they hope to see in the future.
Jul 10, 2023 · Just as Darwin used the fossil record to study life on Earth, scientists can use a "cosmic fossil," the universe's first light, to understand how the cosmos evolved.
Oct 3, 2023 · Discover how an X-ray telescope has revolutionized astronomy and our understanding of the universe. A scientific and engineering marvel, NASA’s Chandra X-ray Observatory has spent two decades (so far) exploring the cosmos unlike any other telescope. What it has found will astound you.
Feb 12, 2022 · NASA surprised the space community by releasing an early first-light picture from the James Webb Space Telescope. "First light" is a double entendre unique to this unparalleled space...
