What can the ocean teach us about life on other planets?

This item was filled under Facts, Ocean Life
Life on Earth is found in conditions ranging from the coldest arctic ice to extremely hot hydrothermal systems on the ocean floor. Microbes are also found in very acidic conditions, very salty conditions, and very alkaline conditions. These microbes are called “extremophiles” (which means 'lovers of extremes').
While conditions on the surface of the Earth where humans are happy are likely to be extremely rare outside of our home planet, the range of conditions in which microbes are found on Earth are more likely to be found on other planets and moons.
