Mars rocks may harbour signs of life

Iron-rich rocks near ancient lake sites on Mars could hold vital clues that show life once existed there, research suggests.

Quote

These rocks – which formed in lake beds – are the best place to seek fossil evidence of life from billions of years ago, researchers say.

A new study that sheds light on where fossils might be preserved could aid the search for traces of tiny creatures – known as microbes – on Mars, which it is thought may have supported primitive life forms around four billion years ago.

It would be just fantastic to discover microbial life on Mars. It would help confirm our Universe is possibly teeming with life. We have already discovered a multitude of planets that have the potential for this .The abscence of aliens as this link suggests then would possibly indicate figuring out the problem of interstellar travel ?

A Martian microbe..how cool would that be ! :yes:

I think that wherever life has a chance to spring up it does. I can't wait for us to explore more and find out!

I agree.When we consider the millions and millions of different species that inhabit and have inhabited this planet it would be naive to consider Earth life as unique. Life takes hold in the most hostile enviorments. Its resilient and seems a natural consequence given enough time

This argument is, unfortunately, a non sequitur. The process by which life fills every available niche, evolution, is not the same as the process by which life forms from none living matter, abiogenesis.

The fact that life is so ubiquitous on Earth, even in conditions which are harsh, allows us to conclude that the same is likely on other planets where life exists. It does not allow us to come to any conclusions about how likely it is that life will occur in the first place.

fair enough..but the obvious multitude of planets out there and given the right enviorment plus billions of years it seems pretty likely IMO

I agree that is seems likely but the universe has a way of doing the unlikely.

Finding life on Mars (or even evidence of extinct life) would be a good clue as to how common life is through out the galaxy. If it arose separately, on two different planets, in our solar system then it would seem highly likely that it is common.
