A Practical Guide to Viewing the Universe
The Milky Way Galaxy is thought to be more than 13 billion years old, which means its first generation of stars formed shortly after the Big Bang. When the James Webb Space Telescope (JWST) looks at objects 12 to 13 billion light‑years away, we see them as they were immediately following their formation soon after the birth of the universe.
Using JWST’s Near Infrared Spectrograph, astronomers studied the light from several remote galaxies, barely visible as faint specks in the image on the facing page. At distances ranging from 11 to 13 billion light‑years, these galaxies were observed as they existed very early in the history of the universe.
Known as Webb’s First Deep Field, this image by the James Webb Space Telescope (JWST) was released on July 11, 2022. In addition to a few nearby stars (recognizable by the blue “spokes”), the image shows the massive galaxy cluster SMACS 0723. The lensing phenomenon is allowing astronomers to study very young galaxies at least 13 billion light‑years away.
