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 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.
Feb 12, 2022 · The new giant space telescope has glimpsed its first starlight, a sunlike star near the constellation Ursa Major. The image shows 18 blurry spots, each a copy of the star, as Webb aligns and calibrates its 18 mirrors.

Jun 22, 2023 · How did the universe become transparent after the Big Bang? New results from the James Webb Space Telescope show that ordinary galaxies cleared the primordial haze with their star formation and supernovae.
See how the Hubble Space Telescope's first image of a star cluster in 1990 revealed its sharper resolution compared to ground-based observatories. Learn about the history and significance of this milestone in astronomy.
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 · Chandra X-ray Observatory. 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. Details.
