THIS FIVE-STORY, BLOOD-RED WATERFALL POURS very slowly out of the Taylor Glacier in Antarctica’s McMurdo Dry Valleys. When geologists first discovered the frozen waterfall in 1911, they thought the red color came from algae.
Description
The existence of the Blood Falls ecosystem shows that life can exist in the most extreme conditions on Earth. Though tempting to make the connection, it does not prove, however, that life could exist on other planets with similar environments and similar bodies of frozen water—notably Mars and Jupiter’s moon Europa—as such life would have to arise from a completely different chain of events.
Even if it doesn’t confirm the existence of extraterrestrial life, Antarctica’s Blood Falls is a wonder to behold both visually and scientifically.
