How deep is the ocean? How far down have humans traveled and what did we find when we went there? This Tech Insider animation shows us the “vast distance between the waves we see and the mysterious point we call Challenger Deep.” Travel down, down, down into the depths of our planet’s oceans to find blue whales, The Midnight Zone, hydrothermal vents, the RMS Titanic, the dumbo octopus, the Mariana Trench, and more.

Watch these videos next: How the Mariana Trench was formed, how the Titanic sank, a CGI animation, and what protects human deep divers down in the Mariana Trench?
