Deep-sea hydrothermal plumes--waters nearly two miles down in the ocean--are home to processes that effect life across the planet. However, high pressure and water temperatures that exceed 300 degrees Celsius have made research on the plumes very difficult.

Microbiologist Jill Mikucki first saw a photo of Blood Falls during a class for her master's degree at Portland State University. It immediately captivated her.

If you have been watching the new series "Cosmos" recently then you have see Tardigrades or "water bears" featured. These creatures are remarkably resistant to a wide range of conditions that humans would consider extreme - if not deadly.

Imagine you're a leech, happily making a living on a turtle in some quiet, freshwater pond. What do you do when winter comes and temperatures in your warm little habitat begins to dip below freezing?

Researchers from the British Antarctic Survey and Reading University have demonstrated that, after over 1,500 years frozen in Antarctic ice, moss can come back to life and continue to grow.

How Deep Inside Our Planet Can Life Exist?

The Sun was once thought to provide energy for all life on Earth - meaning that life could not survive without it. In the 20th century, as astrobiologists began to explore the Earth's most remote and harsh environments, scientists began to question that assumption.

After a three-year overhaul and major upgrade, the United States' deepest-diving research submersible, Alvin, has been cleared to return to work exploring the ocean's depths.

Poison-breathing Bacteria

Buried deep in the mud along the banks of a remote salt lake near Yosemite National Park are colonies of bacteria with an unusual property: they breathe a toxic metal to survive.

Halomonas are a hardy breed of bacteria. They can withstand heat, high salinity, low oxygen, utter darkness and pressures that would kill most other organisms.
