Castor and Pollux Castor and Pollux Castor and Pollux (or in Greek, Polydeuces) were twin half-brothers in Greek and Roman mythology, known together as the Dioscuri. Their mother was Leda, but they had different fathers; Castor was the mortal son of Tyndareus, the king of Sparta, while Pollux was the divine son of Zeus, who seduced Leda in the guise of a swan.

LEDA 1000714 LEDA 1000714 LEDA 1000714 is a ring galaxy in the constellation Crater. LEDA 1000714 is one of a very rare group of galaxies called Hoag-type galaxies, named after the prototype, Hoag's Object – it is estimated that roughly 0.1% of all galaxies are this type. LEDA 1000714 is unusual because it is a Hoag-type galaxy with two nearly round rings, but with different characteristics. It has been nicknamed Burçin's Galaxy, after Burçin Mutlu-Pakdil, the leader of the photometric study of this galaxy. The structure and photometry of LEDA 1000714 was studied with significant detail in 2017. The core of the
