This vent differs from "classic" hydrothermal vents by being colder, although higher than surrounding seawater in levels of minerals like lithium, boron and calcium.

A slow-moving lava flow made of glass is still inching its way down a volcano in Chile, nearly a year after it first erupted, geologists recently discovered.
The lava is made of obsidian, or volcanic glass. Researchers visiting Chile's Puyehue-Cordón Caulle volcano in January 2013 found the obsidian flow was moving, even though the volcano stopped erupting in April 2012, NASA's Earth Observatory reported.

The northern lights recently made an appearance over Alaska's Denali National Park, and as the above photo shows, they did not disappoint.
Northern lights are powerful geomagnetic storms, also known as auroras. They are seen on Earth when charged particles from the sun hit the Earth's atmosphere. The light show was visible across Alaska this past weekend (Jan. 26-27).
