In December 1945, five U.S. Navy bombers set out on a training mission from south Florida, heading east over the Atlantic Ocean. After the planes and their crew failed to return to base, another plane was sent out to find the missing men. Neither the original planes nor the rescue plane were ever seen again. Magazines and newspapers reporting on this mysterious event began to refer to the area as the Bermuda Triangle. Over time, the name stuck, as members of the media continued to catalog other strange disappearances and mysterious happenings in that area. In the last hundred years, countless lives have been lost but nobody is really sure why. People have blamed everything from space aliens to sea monsters for the disappearances of ships and aircraft between Bermuda, Puerto Rico and Miami. But what's really going on? Is it some form of extreme weather? Could it be a rare ocean phenomenon? Or is something else at work? In Curiosity's The Devil's Triangle, a team of investigators go deep into the triangle to explore ocean floor wrecks and stage experiments to tackle the mystery once and for all.

You probably already know that the sun is super old (4 billion years) and incredibly hot (10,000 degrees Fahrenheit). And you might even know that, since it's a giant ball of plasma, it's packed with energy (it will likely blaze for another 6 billion years). It's a friendly neighbor, too -- providing heat and light that make life here on Earth possible. But all isn't entirely rosy. Did you know our sun has a dark side? It's capable of massive destruction! On its surface, a massive storm is brewing -- one so large that it could knock out the power grid, crippling everything from communications systems to banking systems to our water supply. But how prepared are we for a massive solar storm? In this episode, Curiosity goes on a virtual expedition through the heart of the sun to see how these super solar storms form and more.
