- NGC 5286 (also known as Caldwell 84) is a globular cluster of stars located some 35,900 light years away in the constellation Centaurus. At this distance, the light from the cluster has undergone reddening from interstellar gas and dust equal to E(B – V) = 0.24 magnitude in the UBV photometric system. The cluster lies 4 arc-minutes north of the naked-eye star M Centauri. It was discovered by Scottish astronomer James Dunlop, active in Australia, and listed in his 1827 catalog.

Cyrus II of Persia (Old Persian: 𐎤𐎢𐎽𐎢𐏁 Kūruš; c. 600–530 BC), commonly known as Cyrus the Great, was the founder of the Achaemenid Persian Empire. Hailing from Persis, he brought the Achaemenid dynasty to power by defeating the Median Empire and embracing all of the previous civilized states of the ancient Near East, expanding vastly and eventually conquering most of West Asia and much of Central Asia to create what would soon become the largest polity in human history at the time. Widely considered the world’s first superpower, the Achaemenid Empire’s largest territorial extent was achieved under Darius the Great, whose rule stretched from the Balkans (Eastern Bulgaria–Paeonia and Thrace–Macedonia) and the rest of Southeast Europe in the west to the Indus Valley in the east.
