Professor Chris Ballentine, a researcher at the University of Manchester (UK) and colleagues discovered water source in a copper and zinc mine in Ontario, Canada. It lies about 2.4 km from the ground and contains the chemicals necessary for life - such as hydrogen, methane, nitrogen, helium. They said that this water source has age of at least 1.5 billion years old, and the actual number may be longer , Mirror reported.

"This discovery helps us to have better understanding the development of microorganisms in cramped environments, lack of light in the early stages of the globe. They are not affected by the events on the ground", Ballentine commented. Previously, it was only found _ water has age of billions of years in the small rocks on the ground and they run very slow. But from the mineral water flows outside at a rate of Canada nearly two liters per minute.

"The Our ​​Canadian colleagues are trying to find out the source of groundwater that contains live is exsited  or not. However, we have identified how the planets can create and maintain a friendly environment for  microorganisms in billions of years. this means that we have a basis for predicting a similar environment under arid surface of Mars, "said Dr. Greg Holland, a member of the research team working at Lancaster University, said.
