On 30 June, 1908, a huge fireball crossed the night sky and then exploded.
The explosion happened in Siberia, in Russia, in a place called Tunguska. It was very strong. Forty thousand trees in the region of the river Podkamennaya Tunguska were burned and hundreds of animals were killed. Shock waves from the explosion were detected in different places around the world: in England, Germany and America.
