![]() This critical period, which occurred over 13 billion years ago, is when our universe became transparent, enabling us to see the surrounding cosmos as it is today.īefore the Epoch of Reionization, the gas between galaxies was largely opaque, researchers have found. The Epoch of Reionization is a critical moment in our universe's early history that scientists are still trying to understand. James Webb Space Telescope discovers 100s of new galaxies "Now, we can see that some of them are actually extended objects with visible structure."Īnd JWST didn't stop there. "Previously, the earliest galaxies we could see just looked like little smudges," astronomer Kevin Hainline of the University of Arizona said in a statement. ![]() This recent image from Webb offers astronomers an unprecedented, detailed look back in time. Scientists have been studying GOODS for years with various instruments, including the Hubble Space Telescope, Chandra X-ray Observatory, and Spitzer Space Telescope, to name just a few.īut JWST is by far the most powerful telescope to turn its sights on GOODS. ![]() Astronomers who want to spy on the earliest stages of our universe come here to look. It's actually a very famous region called the Great Observatories Origins Deep Survey, or GOODS. What you're seeing here isn't some random patch of space. If you had a lot of time on your hands, you could count 45,000 galaxies in this new photo from the James Webb Space Telescope. The new galaxies are helping scientists unveil the secrets of our early universe like never before. The James Webb Space Telescope released a recent image that contains 45,000 galaxies.Ībout 700 of those galaxies are new discoveries and some of the youngest ever observed. NASA, ESA, CSA, Brant Robertson (UC Santa Cruz), Ben Johnson (CfA), Sandro Tacchella (Cambridge), Marcia Rieke (University of Arizona), Daniel Eisenstein (CfA) James Webb Space Telescope has revealed 45,000 galaxies in this image, hundreds of which have never been seen until now.
