Hubble Uses Galaxy Clusters as Natural Lens to Collect More Data

The Hubble Frontier Fields program uses the galaxy cluster Abell S1063 as a cosmic lens to collect more data about deep space objects. Because of its mass, the gravitational pull of Abell S1063 forms the lensing effect that enables Hubble to locate more galaxies. One of them is an ancient galaxy that is only 1 billion years younger than the Big Bang.
