A Sirius Leonid Meteor
Źródło i prawa autorskie: Wally Pacholka

Opis: In the sky or on the web, did you watch this year's Leonid meteor shower? If you did, meteors flashing through the night sky should be a familiar sight. Recorded last year during the 1998 apparition of the Leonids, this time-exposure of the sky around the constellation Canis Major (big dog) shows the trail of a spectacular fireball meteor. The meteor, by chance, seems to leap from the constellation's brightest star Sirius, near the top right. In the foreground is the beautiful desert scenery of Joshua Tree National Park. At this year's peak of the cosmic dust storm, observers in Europe and Africa reported intense rates of over 1600 meteors per hour for a brief period near 0215 November 18 (UTC). Awe inspiring as they were, the Leonids posed no danger to earthbound skywatchers.
