Tucana

Tucana is a constellation in the southern celestial hemisphere. Its name is Latin for the toucan, and it was introduced in the 18th century by the French astronomer Nicolas-Louis de Lacaille as part of his survey of the southern sky. Today Tucana is one of the 88 constellations recognized by the International Astronomical Union, with boundaries that were formalized in the early 20th century.

The constellation is primarily a southern sky feature and is most readily observed from southern latitudes.

Another significant object associated with Tucana is the Tucana Dwarf Galaxy, a faint dwarf spheroidal galaxy

Observationally, Tucana is a target for southern-hemisphere observatories and for large-aperture telescopes that study globular clusters
