¿ Astronomy Picture of the Day [1]Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2020 April 7 [2]See Explanation.

The direction north on [4]the Earth, the place on your horizon below the northern spin pole of the Earth -- around which other stars appear to [5]slowly swirl, will remain the same. This spin-pole-of-the-north will never move from its fixed location on the sky -- night or day -- and its height will always match your [6]latitude. The further north you go, the higher the [7]north spin pole will appear. Eventually, if you can reach the [8]Earth's North Pole, the [9]stars will circle a point directly over your head. Pictured, a four-hour long stack of images shows [10]stars trailing in circles around this [11]north celestial pole. The bright star near the north [12]celestial pole is [13]Polaris, known as the North Star. The bright path was created by the astrophotographer's headlamp as he zigzagged up a hill just over a week ago in [14]Lower Saxony, [15]Germany. The astrophotographer can be seen, at times, in shadow. Actually, the Earth has two spin poles -- and [16]much the same would happen if you started below the Earth's equator and [17]went south.
