Photos from the James Webb Space Telescope have revealed more than 40 stars within the gravitationally lensed "Dragon Arc" galaxy, 6.5 billion light-years from Earth. It is the largest group of individually imaged stars ever seen at such a distance.
The newly imaged stars are located within the "Dragon Arc," a spiral galaxy roughly 6.5 billion light-years from Earth when the universe was around half its current age. Normally, such distant stars are too far away to be seen in detail. But part of the Dragon Arc has been magnified by gravitational lensing, a phenomenon first predicted by Albert Einstein's theory of general relativity in 1915.

Fascinating! Good article. I try to not imagine the overwhelming amount of algorithms and variables that enable understanding what is seen.
"But the launch of JWST has changed the game. The state-of-the-art telescope is exceptionally good at finding and resolving gravitationally lensed objects, which has helped to open up new windows into the hearts of warped galaxies like the Dragon Arc."
