Large Quantities of Methane Being Replenished on Mars | Universe Today
The chances of anything coming from Mars are a million to one.
I want Mars to be rad as much as anyone but it seems like every time scientist tease us with something like this nothing ever seems to come out of it.
them alien cowpokes been eating beans again, woo.
I think its a lot more likely the methane is from non-biological sources. Gas giants are mainly methane as well, does that mean there might be life on them?
Damn, farting martians. T'aint ne'er seen that a'fer.
They say! OOoooooh OOOoooooH!
This does sound cool if it's real.
What's interesting is that, if you read the article, methane breaks down VERY quickly in Mars' atmosphere. Methane is constantly coming to the surface before breaking down. This means that the methane is being made or seeping up from some kind of deposit. Geologic activity can almost be ruled out because Mars doesn't seem to be geologically active (it seems to have gone dead millions of years ago which accounts for it's lack of a magnetic field, and the lack of a magnetic field is why Mars can't have a thick atmosphere like Earth). So either there's geologic activity that we're not picking up or there's another source for the methane. Many microbes produce methane so it's not unreasonable to wonder if this methane is produced biologically. There could very well be another source, we simply don't know. However, it biological hasn't been ruled out as a possibility.
PS: a thank you out to Dark Convoy who got me hooked on Universetoday.com
You posted pretty much what I was going to post, and you're welcome!
NASA needs to get Quaid's ass to Mars so we can finally get some answers.
Gas giants hold onto their original methane because of their larger gravitational fields, the presence of methane on rocky worlds is more interesting.
Sorry, that was me....
get yo ass to mahrs!!!
Definitely true, but I find it much more likely that this methane is a result of natural gas pockets evaporating due to leftover geologic heat. Even so, these natural gas pockets could be related (either chemically or geographically) to other hydrocarbons, which may be linked to previous life on mars, sort of like how our oil reserves on earth. And that would be pretty cool.
This to me is more plausible. But better yet, I think that its a chemical or geo reaction that we are not even familiar with or can even begin to speculate about. Thats because all we can do is compare what we see on other planets to Earth. We trace Earths sources of Methane & other gases like Oxygen to lifeforms on Earth. But that doesn't mean that Earth rules apply at all on Mars.
