Astronomers used JWST and gravitational lensing to spot 44 individual stars in a galaxy 6.5 billion light-years away.

Taking advantage of a cosmic 'double lens,' astronomers resolved more than 40 individual stars in a galaxy so far away its light dates back to when the universe was only half its present age.
