As in the earlier article (http://wrfrbeameup.blogspot.com/2009/12/mars-rock-may-indeed-contain-signs-of.html) many scientists are of the opinion that life on the red planet may have very likely have existed at some point in the past.
Now according to a new article in Physorg online sent in by Shaun Saunders, there is compelling evidence to suggest life still flourishes beneath the surface. The article centers around the levels of Methane on Mars. Many scientists believed that the levels were being maintained through meteor impacts. But recent research shows that the amount of impacts is not sufficient to maintain methane at its current level. Methane is very short lived. In Mars' harsh environment, it is broken down in just a few hundred years. But instead of dissipating, the gas is being replenished and the levels are being maintained higher than can be supplied by meteor impacts.

From the article:
- This leaves only two plausible theories..... Either there are microorganisms... that are producing methane gas ... or methane is being produced as a by-product of reactions between volcanic rock and water.
