- This small and insignificant constellation in the southern hemisphere, representing an engraver’s chisel, is one of the inventions of the 18th-century French astronomer Nicolas Louis de Lacaille. He introduced it on his map of the southern stars published in 1756, where he gave it the French name les Burins (although in the accompanying star catalogue it was listed as Burin, singular). On the second edition of the map in 1763 this was Latinized to Caelum Scalptorium. In 1844 the English astronomer John Herschel proposed shortening the name to Caelum. Francis Baily adopted this suggestion in his British Association Catalogue of 1845, and it has been known as Caelum ever since.

Franklin Delano Roosevelt (1882-1945) was the longest serving President in US History, serving three full terms and starting his fourth when he died. No other President had even won a third term (a couple had tried — Grant and T.R. — but none were elected). And, thanks to the 22nd Amendment, no President since will be able to challenge his length of service (barring the very unlikely event of the 22nd being repealed).
