Sup Travellers?! That probe that landed on the comet as part of the Rosetta mission wasn't a big waste of money after all. According to reports from the Wall Street Journal, the probe has detected organic molecules in the comet's atmosphere.
It is still unclear what kind of organic molecules are in the atmosphere but they could very well hold a key to early life on Earth.
Organic molecules are any that contain carbon. We, being carbon-based life forms, are all made of such molecules, which may actually have extraterrestrial origins. Simulations have suggested that ultraviolet radiation bombarding icy particles can form organic molecules out in space. In turn, comets could have brought those molecules to Earth, providing the raw materials for life to emerge on our planet.
At this point the organic molecules can be anything from Methane to complex amino acids, the building blocks of proteins.
There's still a lot more to be done as scientists still need to analyze samples from beneath the comet's surface since their first attempt failed. There might be another chance if Philae gets more sunlight as the comet speeds toward the sun. Meanwhile Philae has gone dark, but scientists are still hard at work analyzing the data it sent back.
I don't think that there are going to find any complex organic compounds on the comet but I strongly believe that there is Methane. There have been multiple previous reports about Methane in space.
Titan, the largest moon of Saturn has Methane so I won't be surprised if the compound is found on random comets floating through space.
There is some speculation that comets brought organic molecules to earth and even though it seems like a valid theory there isn't enough evidence but I don't think that we need much evidence to prove that my name is Trinikid and you've just been informed.
