Frontier Fields

The Frontier Fields was a NASA project that used the Hubble Space Telescope to photograph some of the universe's most distant and faintest galaxies. By targeting massive galaxy clusters, the project utilized a phenomenon called gravitational lensing, where these clusters bend and magnify light from galaxies far behind them. This allows astronomers to see and study galaxies that would otherwise be too faint or small to observe. The goal was to explore the early universe, understand galaxy formation, and uncover objects that are critical to understanding cosmic history.
