🌞 NASA Captures Mercury Crossing the Sun! 🪐 . In November 2019, NASA’s Solar Dynamics Observatory (SDO) recorded a rare cosmic event — Mercury passing directly between Earth and the Sun. This phenomenon, called a Transit of Mercury, won’t happen again until 2032! 🔍 Why is this significant? • It helps scientists measure the Sun’s atmosphere with extreme precision • Improves our understanding of planetary orbits and orbital mechanics • Sharpens techniques for detecting exoplanets using transit
