One of the first publicly released images from the James Webb Space Telescope , released on July 11, 2022, captured at least 7,000 galaxies in a sparkling deep field view.NASA's James Webb Space Telescope has helped astronomers determine the distance to nearly 200 galaxies and galaxy clusters formed in the universe's early days.
Other findings came to light as well. The team spotted three objects with greater-than-normal densities, or overdensities, than one would expect in a lone galaxy. The discovery suggests that SMACS 0723 may host three newly found galaxy clusters roughly eight to 10 billion light-years away from Earth. revealed in September 2022. Sparkler is nine billion light-years away and could host the universe's first star clusters.
Members of the Canadian NIRISS Unbiased Cluster Survey, including the study authors, will use the instrument once again during JWST's second year of observations. They plan to peer even further into the deep field to seek new galaxies, galaxy clusters and overdensities.
