#TBT to @nasa's #APOD from yesterday. The universe is insanely #beautiful. Here's the explanation from #NASA for what you see: What's that #green streak in front of the Andromeda #galaxy? A #meteor. While photographing the #Andromeda galaxy last Friday, near the peak of the #Perseid Meteor Shower, a sand-sized rock from deep #space crossed right in front of our #MilkyWay Galaxy's far-distant #companion. The small meteor took only a fraction of a second to pass through this 10-degree field. The meteor flared several times while braking violently upon entering #Earth's #atmosphere. The green #color was created, at least in part, by the meteor's #gas glowing as it vaporized. Although the exposure was timed to catch a #Perseids meteor, the orientation of the imaged streak seems a better match to a meteor from the Southern Delta Aquariids, a #meteor shower that peaked a few weeks earlier. 📷 Image Credit & Copyright: Fritz Helmut Hemmerich #space #beauty #cosmos #luck #timing #perfectlytime...
