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. 2024 December 4 IFRAME: [2]https://www.youtube.com/embed/7QB_MOemCqs?rel=0 Driveway Analemma Video Credit & Copyright: [3]Nick Wright Explanation: Does the Sun return to the same spot on the sky every day? No. A more visual answer is an [4]analemma, a composite of sky images taken at the same time and from the same place over a year. At completion, you can see that the Sun makes a [5]f[6]i[7]g[8]u[9]r[10]e [11]8 on the sky. The [12]featured unusual analemma does not, however, picture the [13]Sun directly: it was created by looking in the [14]opposite direction. All that was required was noting where the [15]shadow of an edge of a [16]house was in the [17]driveway every clear day at the same time. Starting in March in [18]Falcon, [19]Colorado, [20]USA, the photographer methodically marked the shadow's 1 pm location. In one frame you can even see the [21]photographer himself. Although this analemma will be completed in 2025, you can start drawing [22]your own driveway analemma -- using no fancy equipment -- as soon as today.
