Today’s Image of the Day from the European Space Agency (ESA) shows the impact of an air blast over Tunguska, Russia, after a meteor disintegrated only a few miles from the Earth’s surface in 1908. The explosion had the force of an estimated 15 megatons of TNT and flattened 770 square miles of forest.

According to the ESA, there are over 600,000 asteroids in the Solar System, and 16,000 of those have been designated as near-Earth objects.

On June 30, the ESA will stream a live broadcast for Asteroid Day 2018. Experts will share fascinating insight, including recent developments in the search for risky asteroids.
