Description
Deux nuits pour une seule photo, 1h30h d’exposition pour le ciel et 50h de donnรฉes pour les รฉtoiles filantes en utilisant 4 camรฉras et 3 filtres astronomiques pour combattre la pollution lumineuse.
Au temps des Grecs et des romains, les gens croyaient qu’ร chaque personne correspondait une รฉtoile. Quand la personne mourait, elle tombait du ciel et devenait une รฉtoile filante.
C’est unique d’รชtre lร , seul dans le silence au milieu de nulle part et en plรฉnitude face ร cette nature

A Meteor Wind over Tunisia
Image Credit & Copyright:ย Makrem LarnaoutExplanation:ย Does the Earth ever pass through a wind of meteors? Yes, and they are frequently visible asย
meteor showers. Almost all meteors are sand-sized debris that escaped from a Sun-orbiting comet or asteroid, debris that continues in an elongatedย
orbit around the Sun. Circling theย
same Sun, our Earth can move through anย
orbiting debris stream, where it can appear, over time, as aย
meteor wind. The meteors that light up inย
Earth’s atmosphere, however, are usually destroyed.ย Their streaks, though, can all be traced back to a single point on the sky calledย
the radiant. Theย
featured imageย composite was taken over two days in late July near the ancientย
Berberย villageย
Zriba El Aliaย inย
Tunisia, during the peak of theย
Southern Delta Aquariidsย meteor shower. The radiant is to the right of the image.ย
A few days agoย our Earth experienced the peak of aย
more famousย meteor wind —ย
the Perseids.
