The 1908 Tunguska event, the largest asteroid-related blast in history, is commemorated annually on June 30th as International Asteroid Day. NASA satellite imagery reveals no impact crater at the Siberian blast site, despite eyewitness accounts describing a fiery explosion and widespread devastation. While the exact cause remains debated (asteroid or comet), the event underscores the potential danger of near-Earth objects (NEOs). NASA's Planetary Defense Coordination Office monitors NEOs, bolstered by international collaborations like the International Asteroid Warning Network, highlighting the need for global preparedness against asteroid threats.
