Why does the Moon appear larger when it's positioned near the horizon compared to when it's higher in the sky?
The phenomenon of the Moon appearing larger near the horizon remains an unsolved scientific mystery that has puzzled experts for over 2,000 years, dating back to Aristotle's observations. Despite extensive research and ongoing scientific experiments, there is still no definitive consensus on the exact cause of this optical illusion. While scientists have proposed various theories including atmospheric effects and the Ponzo illusion (a visual perception phenomenon), the complete explanation continues to elude researchers, making it one of astronomy's most enduring puzzles.

How is artificial intelligence transforming and optimizing processes across different industries and sectors of society?
AI is revolutionizing multiple domains by acting as an intelligent automation layer across industries. In healthcare, it serves as a diagnostic assistant, analyzing medical images to detect tumors and predicting future diseases while helping develop new drugs more efficiently. In astronomy, AI autonomously identifies celestial objects and optimizes telescope performance to discover exoplanets and cosmic events. The technology extends into education as a personalized teaching assistant, creating customized learning experiences and providing instant feedback. In finance, AI monitors transactions for fraud prevention and assists in trading decisions. Transportation benefits through self-driving capabilities and route optimization, while agriculture uses AI for crop monitoring and precision farming. From entertainment recommendations to robotic automation in warehouses, AI consistently demonstrates its ability to enhance productivity, accuracy, and decision-making across virtually every sector of modern society.
