A ship full of marine scientists is floating over the deepest part of the world: the Pacific Ocean's Mariana Trench. They're sending down probes to study life in one of the most hostile environments on the planet.
This week the researchers are targeting the two deepest spots in the trench — the Sirena Deep and the Challenger Deep — which each extend down about 7 miles beneath the ocean's surface.
