What is the significance of the Webb telescope's discovery of 44 ancient stars in the Abell 370 galaxy cluster?

Using gravitational lensing, NASA's Webb telescope identified 44 ancient stars within the Dragon Arc of the Abell 370 galaxy cluster, located 6.5 billion light-years from Earth. This surpasses previous discoveries by the Hubble telescope, which only found around seven stars in similar distant galaxies. Many of these stars are red supergiants, comparable to Betelgeuse.
