The NASA’s JWST telescope has discovered what could be the earliest star clusters in the universe.
JWST spotted the five proto-globular clusters — swarms of millions of stars bound together by gravity — inside the Cosmic Gems arc, a galaxy that formed just 460 million years after the Big Bang.
The Cosmic Gems arc gets its name from its appearance: When seen from our solar system, the star-studded galaxy looks like a hair-thin crescent due to the powerful gravitational influence of a foreground galaxy, which magnifies and distorts the distant galaxy’s appearance.
