Messier 7, also known as the Ptolemy cluster, was identified in ancient times, first noted in writing by Ptolemy in 130 AD. It is located in the constellation Scorpius and is just under 1,000 light years away, which means that the light that this photo collected was created by these stars just a few decades before the Norman Conquest of England in 1066.
