Cosmic telescope effect finds Universe's brightest galaxies
NASA's Hubble Space Telescope has captured close-up views of the universe's brightest infrared galaxies, 10,000 times brighter than Milky Way. The images were captured using a phenomenon called gravitational lensing, where light from a distant star is bent by another star's gravity magnifying it like a telescope before it reaches Earth. Lensing helps find distant exoplanets and stars.
