Summary

Gravitational lensing is one of astronomy's best tricks for seeing the early universe. When a massive galaxy cluster sits in between the observer and a distant object, its gravity bends and magnifies the distant object's light, acting like a giant natural magnifying glass. Galaxies that would otherwise be too faint to spot suddenly come into view because of gravitational lensing. Using this effect, astronomers have now identified a galaxy nicknamed Misty Moons that existed when the universe was less than 500 million years old.
