Why Antarctica's Blood Falls appears to bleed red across the ice
In short: Antarctica's Blood Falls is a striking natural feature that seems to bleed onto the ice. This video follows researchers as they investigate the source of this red color, the resilient microbes living within the glacier, and what this extreme environment reveals about the potential for life on other planets.
Located in the Dry Valleys, about 60 miles from McMurdo Station, Blood Falls emerges from the Taylor Glacier and flows into Lake Bonney. The site has intrigued scientists for decades, prompting investigations into its unique chemistry and biology.
Microbiologist Jill Mikucki and hydrogeologist Peter Doran explain that the site is home to charismatic microbes. By using advanced technology, including probes, cameras, and sensors suspended from helicopters, researchers study these organisms to better understand how life might exist on celestial bodies like Mars, Jupiter's moon Europa, and Saturn's moon Enceladus.
