Parallel field of Abell S1063

This part of the sky was observed in parallel with the galaxy cluster Abell S1063 and is also part of the Frontier Fields programme. While one of Hubble’s cameras observed the galaxy cluster itself, another simultaneously captured the spectacular scene pictured above, of an “unremarkable” patch of space. While not having the advantage of strong gravitational lensing this parallel field observation is still nearly as deep as the Hubble Ultra-Deep Field. Combined with other deep fields it helps astronomers understand how similar the Universe looks in different directions.
