Twin “Black Smokers”
Photograph by Emory Kristof

Billowing from otherworldly chimneys a mile and half down, seafloor hot springs spew water heated to as much as 760°F (404°C) by magma deep within the Earth. Carrying a stew of dissolved minerals, these “black smokers” create oases in the sunless cold of the deep ocean that support dense communities of organisms—most unknown to science as little as 25 years ago.
