Subj : Daily APOD Report To : All From : Ben Ritchey Date : Sun Aug 12 2018 13:01:47 Astronomy Picture of the Day Astronomy Picture of the Day Discover the cosmos! [1] Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2018 August 12 [2] Meteor before Galaxy Image Credit & Copyright: Fritz Helmut Hemmerich [3] Explanation: What's that green streak in front of the Andromeda galaxy? A meteor. While photographing the Andromeda galaxy [4] in 2016, near the peak of the Perseid [5] Meteor [6] Shower [7] , a sand-sized rock from deep space crossed right in front [8] of our Milky Way Galaxy [9] 's far-distant companion. The small meteor [10] took only a fraction of a second to pass through this 10-degree field. The meteor flared [11] several times while braking violently upon entering Earth's atmosphere [12] . The green color [13] was created, at least in part, by the meteor's gas glowing as it vaporized. Although the exposure [14] was timed to catch a Perseids meteor [15] , the orientation of the imaged streak seems a better match to a meteor from the Southern Delta Aquariids [16] , a meteor shower [17] that peaked a few weeks earlier. Not coincidentally, the Perseid Meteor Shower [18] peaks again tonight [19] .
