118 years ago today, the sky split in two. That's how one witness described the Tunguska Event, a mysterious explosion over the skies of eastern Siberia. It began as a column of blue light moving through the atmosphere over the Podkamennaya Tunguska River. Minutes later, a flash filled the horizon, and a deafening boom shook the earth.
This phenomenon, recorded on June 30, 1908, would become known as the largest impact event in recorded history. Shockwaves from the blast could be measured from across the globe. An estimated 80 million trees were flattened. For nights after, the skies over Eurasia glowed. As massive as the impact was, much remains mysterious about the Tunguska Event, even down to what exactly caused it.
