A photograph featured by NASA's Astronomy Picture of the Day shows a fireball meteor flashing across the northern horizon under the constellation Ursa Major. The image was taken on November 14, 2017, from a mountain pass in Italy's Dolomite Alps, and it captured the meteor by chance during the camera's exposure.
The meteor was seen to flash from east to west across the horizon, and its appearance was particularly stunning against the soft pinkish colors of the fading twilight. The fireball meteor was widely reported in European skies, with many sightings documented by the American Meteor Society and the International Meteor Organization, making it one of the most reported fireball events ever.
The meteor's track over Germany was consistent with its origin near the active radiant of the Northern Taurid Meteor Shower, which is associated with dust from Encke's comet. This information provides context for the meteor's appearance and origin.
The photograph itself shows a serene and rugged landscape, with snowy peaks and the village of La Villa, Alta Badia, nestled below, and the constellation Ursa Major hanging over the northern horizon. The image is a striking example of the beauty and wonder of the natural world, and it highlights the importance of capturing and documenting rare astronomical events.
The fireball meteor's appearance in the photograph is a remarkable coincidence, and it adds to the image's beauty and significance.
