Where is the Hubble Frontier Fields region?

The Hubble Frontier Fields are not one place but six cluster fields and six nearby parallel fields selected for their extreme lensing power. These regions are centered on massive galaxy clusters that bend light from very distant background galaxies. Hubble and other telescopes used them to detect galaxies from the early universe that would otherwise be too faint to see. The project began in the 2010s and became a key tool for studying early galaxy formation.
