Norma

Norma is a small and inconspicuous constellation in the southern hemisphere between Scorpius and Centaurus. Its name is Latin for normal, referring to a right angle, and is variously considered to represent a rule, a carpenter's square, a set square or a level. Norma, originally named l’Equerre et la Regle in French, was one of the constellations invented by Abbé de Lacaille in the middle of the 1750s, when he was measuring about 10,000 stars at the Cape of Good Hope.[1] Norma represents a carpenter's square, used in the Age of Exploration by carpenters on exploratory vessels.The Milky Way passes through Norma.
