The final observations of the Frontier Fields project are now in the books, although the hard work of analyzing the data has just begun. Views of the stunningly beautiful galaxy cluster Abell 370 and its parallel field mark the end of this ambitious observing campaign, which began in October 2013.
The photogenic Abell 370 contains an astounding assortment of several hundred galaxies tied together by the mutual pull of gravity. Located approximately 4 billion light-years away in the constellation Cetus, the Sea Monster, this immense cluster is a rich mix of a variety of galaxy shapes.
