The very first deep field image from the James Webb Space Telescope (JWST) has just delivered a new treasure from the early Universe.
In a splash of light that has traveled for 9 billion years to reach us, astronomers have spotted clusters of stars sparkling around a distant galaxy they have named the Sparkler.
"We hope the knowledge that globular clusters can be observed from such great distances with JWST will spur further science and searches for similar objects." However, we don't know a lot about how they formed, or where they came from. And it's pretty challenging to figure out how old they actually are.Finding them in the early Universe, with enough data to determine their nature, isn't easy either. Across such vast distances, small, dim objects become much harder to resolve.
