Astronomy Picture of the Day [1]Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2025 August 10 [2]A night sky is shown above a road going off into the distance. An unusual area of brightened sky that does not block background stars appears diagonally from the lower right across the sky. Please see the explanation for more detailed information. Zodiacal Road Image Credit & Copyright: [3]Ruslan Merzlyakov ([4]astrorms) Explanation: What's that strange light down the road? [5]Dust orbiting the Sun. At certain times of the year, a band of sun-reflecting dust from the inner [6]Solar System appears prominently just after sunset -- or just before sunrise -- and is called [7]zodiacal light. Although the [8]origin of this dust is still being researched, a leading hypothesis holds that zodiacal dust originates mostly from faint [9]Jupiter-family comets and slowly spirals into the [10]Sun. Recent analysis of [11]dust emitted by Comet 67P, visited by ESA's robotic [12]Rosetta spacecraft, bolsters this hypothesis. [13]Pictured when climbing a road up to [14]Teide National Park in the [15]Canary Islands of [16]Spain, a bright triangle of [17]zodiacal light appeared in the distance soon after sunset. [18]Captured on June 21, 2019, the scene includes bright [19]Regulus, the [20]alpha star of the constellation Leo, standing above center toward the left. The [21]Beehive Star Cluster (M44) can be spotted below center, closer to the horizon and also [22]immersed in the zodiacal glow.
