This is Mammoth Hot Springs located inside Yellowstone National Park, near the North Entrance.

Billions of heat-loving microorganism called "thermophiles" create the carpet of the spring. Thermophiles thrive in this hot spring, creating the tapestry of color. Some microorganisms live on sunlight. Others live on gases, such as hydrogen sulfide. (Spirulina is just one of many thermophiles living at Mammoth Hot Springs. When seen through a microscope, it's spriral shape is easy to detect.)

Finding a Niche:
As you look at the spring's patchwork of colors, you are looking at a world of thermophiles. Many species flourish here, each in a unique niche created by subtle differences in the spring.
- Temperatures vary - spots too hot or too cool for some are perfect for other thermophiles.
- Gases, most potent at the vent, are nutritious for some, but deadly for others.
- Swirling water or calm pools create different living conditions.
- The formation's miniature hills and valleys capture light and cast shadows, habitats for sun or shade-loving thermonphiles.

Extraordinary Life:
You are looking at billions of microorganisms living and prospering amid gases and heat, conditions that are lethal to humans. Some scientists study these remarkable thermophiles and their hot spring habitats to determine whether other worlds might support life. They are also learning about the kinds of evidence to search for in their quest to find life beyond Earth.
