A massive explosion in the sky occured above Siberia. Without warning, forces equivalent to 185 Hiroshima bombs cut through the air.

770 square miles of forests were flattened in an instant and all animal life was destroyed.

Scientists have studied this event, knows as the Tunguska Event ever since. For a long time it was a complete mystery but over time the most common theory is that the explosion was an air burst from an exploding comet or meteor which had penetrated Earth’s atmosphere.

Due to the remoteness of the location there were no confirmed human casualties but still, pretty scary. If it happened above a metropolitan area it would be immediate death for millions.

Over 1000 papers have been written and there are many different theories, but the Tunguska Event fascinates me.
