Tunguska Event Mystery

At 7.15 am, 30 June 1908, a large fireball shot past the sky like lightning and exploded above the Tunguska River in Siberia (Russia).

The immediate impact was felt 70 km away. Moments later, seismic tremors were recorded about 900 km away. The tremors travelled around the earth twice! The explosion scorched and levelled, in a butterfly shape, 2000 sq km of Siberian forest. (about 3 times the size of Singapore) For several weeks, the night sky was exceptionally bright throughout Europe and Western Siberia.

Due to internal conflicts and a lack of resources, the first expedition reached the site only in 1930. It was led by Professor Leonid Kulik.

There were many theories trying to explain the event: alien spaceship crashed? Nuclear explosion? Meteorite? Testing of a new military weapon?

The most logical explanation was that a medium sized meteorite exploded in mid air. Scientists believe the meteorite was reduced to dust and dispersed high into the atmosphere. This dust was carried around the globe. The help to explain 2 facts: firstly, why there was no crater at the site. Secondly, the strange glow in the night sky was caused by the dust reflecting sunlight.

Subsequent expedition found particles of dust which scientific tests found a close match with similar dust collected in Antarctica.

Ps: this is scary man! What if the meteorite hit our city tomorrow? Are you prepared to die?
