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.
I'd never heard of this Peter, but I've just looked it up. It's a fascinating event and it's mental that something like that can happen.
I'm sure there'll be some interesting books on it out there, could be my next read, although I'll end up settling for youtube videos no doubt 
I really want to learn more about Rasputin too.. a very interesting character from history IMO.
Rasputin really was a bit of a character. I like learning about historical figures. One of my favourites was Marc Anthony. Ghenghis Khan was a bit of a boy too.
Regarding that thing in Siberia, they reckon it was about 15 mega tonnes. In 2004 an asteroid, 99942 Apophus, was observed to have a trajectory which might hit earth in 2029 and with a narrow miss might hit again in 2036. It would have a 1200 megatonne impact.
Plans were made to look at diverting it, and millions were spent. We have even sent a craft to study it. But now it is looking like passing by us by 31000km. That’s still closer than satellites.
Chance of an impact though is now considered to be 150,000 to 1. Phew.
