It’s safe to say that we know more about outer space than what’s in the deepest hole on Earth. The tunnels that infiltrate earth and what’s remained underneath it all these years has remained a mystery until now.
The Kola Superdeep Borehole (which took 24 years to drill) gave us insight into more of earth’s secrets when it drilled into its crust more than 7.5 miles deep. That’s deeper than the deepest point of the ocean. The hole sits on the Kola Peninsula of Russia.
Scientists found microscopic fossils of single-celled organisms and water approximately 4.3 miles down. What was even more surprising was how outrageously hot it was; a blistering 356°F that caused the drilling to stop.
Drilling ended in 1994 and scientists discovered that the distance to the center of the Earth is nearly 4,000 miles. Their 7.5 miles journey didn’t even make a dent.
