Well, actually they found more than organic carbon. Some of the other elements which are necessary to Earth life, such as sulfur, were also found. The real interesting data should come from the mountain where rocks of different ages are exposed. We won't see that data for some time.

If you were an alien looking for life on Earth you would note the presence of liquid water and be hopeful. You would note the large amount of free Nitrogen and Oxygen, both of which are sufficiently reactive to be doomed to be locked up in soil and rocks unless replenished constantly and you would be optimistic. Living organisms keep our atmosphere composition in the highly improbable state of being composed of about 20% Oxygen and over 70% Nitrogen. If we spotted a similar atmosphere we would be confident that it is a world like our own.

Traces of CO2 would be intriguing to alien scientists. That is a fairly stable gas but it would seem odd that there is so little of it, but just the right amount to keep water liquid. Mars and Venus have atmospheres are are 98% or more CO2, one very thick and hot, one very thin and cool. Earth has a fine regulatory system that keeps things improbable and lively. It is life itself.

Methane would neither confirm life nor disprove it, but methane can be a sign of life. And of course, the man-made greenhouse gases would be a dead giveaway that the planet is inhabited by morans who haven't learn to work within the system rather than against it.

Mars has methane although it is not known whether the source is biological or geological. It is leaking out of the ground in some interesting places where life would be likely on, say, Antarctica.

The surface of Mars is rich in perchlorates. This is not a good sign, but it is not impossible that bacteria can use perchlorates to survive under harsh conditions or produce them as waste.

Life on Mars, if it was ever there and if it survives, is most likely underground, in the vicinity of volcanic vents and possibly mud volcanoes, liquid water below the surface, or possibly in the ice caps. It'll take some time to locate, but by looking at a variety of rock strata scientists should form a clearer geological picture of the history of Mars over the last four billion years, during which life very slowly evolved. About three billion years of that time life consisted of microbes.

Most of the work of evolution went into building cells and learning to control genetic information and gene expression so you get accurate transmission of information but not TOO accurate transmission, which would mean excessive conservatism and lack of innovation and adaptation. Once you have cells, you can stick them together into all sorts of interesting shapes like little computerized Lego bricks with tiny minds of their own. You can even build brains, although this is highly improbable and possibly counter-productive.

Like walking, evolution is a sort of controlled falling on your face.

That Reilly Monster: FTFA: Even with carbon and water, life needs other chemicals, such as sulfur, oxygen, phosphorous and nitrogen, to form and evolve.

Statements like this irk me. Would it be too much to ask for "life as we understand it needs other chemicals..."?


Bothered me as well. Should have read "Even with carbon and water, life on Earth needs yaddayaddayadda".

Silicone based life-forms frown on this reporters shenanigans.

ObscureNameHere: Did they find out where Han's vest disappeared to, then re-appeared from, just before he was frozen?

/go watch TESB closely....


WTF are you talking about? Han didn't wear his vest on Bespin, he had a jacket, which was gone when they brought him to the chamber and remained off through the freezing process and when he was thawed out on Tatooine.

Likewise, it's very evident that he's not wearing any sort of vest while in the carbonite.

...now that said, the arm-shackles that were wrapped around his biceps seems to have not survived the freezing process intact, since they aren't there when he thaws out.

See the difference? Are we clear now? What life forms are we talking about, exactly?

Go search for better articles. Carbon compounds were found.

I'm not breaking out the champagne over it, but it's more interesting than elemental carbon.

Also, Viking found these too but were dismissed as contamination, mostly because they had no way of knowing whether they came from earth or not. Later missions to mars would be better controlled to reduce this potential contamination.

4th most common element in the universe.
Atmosphere mostly CO2
Nearest planet loaded with carbon

Truly shocking finding!

So they found traces of carbon on Mars? Meh...I guess NASA never heard of carbonaceous chondrites, eh?

This is a shiatty headline and article, some careful reading is required to get any value out of it. They found carbon COMPOUNDS, specifically organic ones. They're not inherently indicative of life, but they are a requirement for life to exist which means it's one more item that Mars has which would allow for life to exist there.

Since Carbon is present in the entire universe well into the hundreds of parts per million, I would have been more surprised if they didn't find any.
