This view represents more than 50% of the COSMOS-Web survey: the largest, deepest view of the Universe ever acquired with JWST. It provides us with our deepest wide-field view of the Universe ever taken, revealing how galaxies and larger structures evolve throughout cosmic history. Credit: ESA/Webb, NASA & CSA, G.

Technology The WorldA Part of the Universe Can Now Be Seen More Clearly Than Ever
Launched in 2021, NASA’s James Webb Space Telescope (JWST) was sent to map our universe’s wonders with the most incredible precision ever. The full 166-megapixel image obtained through the COSMOS-Web survey is finally available to the public.
The galaxy cluster surveyed is located 9.9 billion light-years away. Since JWST uses filters extending to much longer wavelengths than Hubble Space Telescope’s limit, JWST can reveal details that are completely invisible to Hubble.
The COSMOS-Web survey mapped 0.6 square degrees of the sky—or the area of three full Moons—with the James Webb Space Telescope’s Near Infrared Camera instrument while simultaneously mapping 0.2 square degrees with the Mid Infrared Instrument. This data should help explain how the universe grew. Our universe is 13.8 billion years old and contains trillions of galaxies with sextillions of stars.
