A Cool GIF of a 2025 Perseid
Explanation: The camera battery died about 2am local time on August 12, while shooting in the bright moonlit skies from a garden in Chastre, Brabant Wallon, Belgium, planet Earth. But not before it captured the frames used to compose this cool animated gif of a brilliant Perseid meteor and a lingering visible trail known as a persistent train . The Perseid meteor, a fast moving speck of dust from the tail of large periodic Comet Swift-Tuttle , was heated to incandescence by ram pressure and vaporized as it flashed through the upper atmosphere at 60 kilometers per second . Compared to the brief flash of the meteor, its wraith-like trail really is persistent. A characteristic of bright meteors, a smoke-like persistent train can often be followed for many minutes wafting in the winds at altitudes of 60 to 90 kilometers.
