﻿ 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. 2022 August 16 [2]The featured image shows a composite image capturing many meteor streaks above the ruins of an ancient village. Please see the explanation for more detailed information. A Meteor Wind over Tunisia Image Credit & Copyright: [3]Makrem Larnaout Explanation: Does the Earth ever pass through a wind of meteors? Yes, and they are frequently visible as [4]meteor showers. Almost all meteors are sand-sized debris that escaped from a Sun-orbiting comet or asteroid, debris that continues in an elongated [5]orbit around the Sun. Circling the [6]same Sun, our Earth can move through an [7]orbiting debris stream, where it can appear, over time, as a [8]meteor wind. The meteors that light up in [9]Earth's atmosphere, however, are usually destroyed. [10]Their streaks, though, can all be traced back to a single point on the sky called [11]the radiant. The [12]featured image composite was taken over two days in late July near the ancient [13]Berber village [14]Zriba El Alia in [15]Tunisia, during the peak of the [16]Southern Delta Aquariids meteor shower. The radiant is to the right of the image. [17]A few days ago our Earth experienced the peak of a [18]more famous meteor wind -- [19]the Perseids.
