An explosion flattened a vast Siberian forest
On 30 June 1908, the Tunguska explosion struck Siberia, flattening roughly 2,150 square kilometres of forest. It is generally attributed to a celestial object exploding in the atmosphere. Whether the object was an asteroid or a comet remains debated.
A blast in the sky left an enormous mark on the ground.
