Take Flight with the Toucan and the Cluster: It may be famous for hosting spectacular sights, but the southern constellation of Tucana (The Toucan) also possesses a variety of unsung cosmic beauties, such as this open star cluster located within the Small Magellanic Cloud just under 200,000 light-years away. Open clusters such as this are collections of stars weakly bound by the shackles of gravity, all of which formed from the same massive molecular cloud of gas and dust. Because of this, all the stars have the same age and composition, but vary in their mass because they formed at different positions within the cloud.
