Blood on the antarctica
Roughly 2 million years ago, a small amount of water was trapped beneath a glacier mixed with an ancient community of microbes. They continue to evolve even today, without access to light, water or oxygen. It has a very high salinity and is rich in iron, which gives its red color.
And a small crack allows a small amount to squeeze out since it was first discovered in 1911. Now it just looks eerie but it raises the possibility that life form can evolve under extreme conditions. Something to think about when we question about life on icy planets.
Here are the pictures:
