Word of the Day: Astrolabe

Today's word of the day 'Astrolabe' refers to an ancient astronomical instrument that once helped people navigate both time and space. An astrolabe is a small, handheld instrument once used to observe the sky and calculate the position of stars, planets, and the sun. Long before GPS or even the sextant, it helped astronomers, sailors, and scholars understand where they were—and what lay above them.
