Arctic Circle 

1550s in astronomy, in reference to a celestial circle, a line around the sky which, in any location, bounds the stars which are ever-visible from that latitude (in the Northern Hemisphere its center point is the celestial north pole); the concept goes back to the ancient Greeks, for whom this set of constellations included most prominently the two bears (arktoi), hence the name for the circle (see arctic). In Middle English it was the north cercle (late 14c.).

In geography, from 1620s as "the circle roughly 66 degrees 32 minutes north of the equator" (based on obliquity of the ecliptic of 23 degrees 28 minutes), marking the southern extremity of the polar day, when the sun at least theoretically passes the north point without setting on at least one summer day and does not rise on at least one winter one.

Thule 

region or island at northernmost part of the world, Old English, from Latin, from Greek Thyle "land six days' sail north of Britain" (Strabo, quoting a lost portion of a work by Polybius, itself based on a lost account of a voyage to the north by 4c. B.C.E. geographer Pytheas). The identity of the place and the source of the name have sparked much speculation; Polybius doubted the whole thing, and since Roman times the name has been used in a transferred sense of "extreme limits of travel" (Ultima Thule).

The barbarians showed us where the sun set. For it happened in those places that the night was extremely short, lasting only two or three hours; and the sun sunk under the horizon, after a short interval reappeared at his rising. [Pytheas]

The name was given to a trading post in Greenland in 1910, site of a U.S. air base in World War II.
