The Tunguska Event is the largest impact event on Earth ever recorded. On January 30, 1908, something hit the Earth’s atmosphere or ground with a force 185 times greater than that of the atomic bomb that hit Hiroshima. Problem is, it was in such a remote area that nobody could get there to study it until almost 30 years later. What really happened in that forest in Siberia remains a mystery but we have a few theories of what we think happened.
