There are thousands of stunning waterfalls worldwide. However, none are as unique as Antarctica's Blood Falls. The aptly-named waterfall, which flows from the tip of the Taylor Glacier, spurts out bright red water. The existence of this five-story-tall waterfall has been known for over a century. But the reason behind its crimson waters has remained a mystery. Now, a team led by  W. Berry Lyons of The Ohio State University may have finally found the answer.
