View Full Version : The Early Earth's Atmosphere was Similar to Titan

The thick organic haze that shrouds Titan is similar to what we had here on Earth billions of years ago; an environment that might have helped early life get a foothold. NASA researchers set up several experiments that reproduced the atmosphere in the early Earth and Titan today. The Earth experiments produced tremendous amounts of organic material, which could have been one of the ways life first appeared.

Wow, this project is so cool. I wish to know how life was formed in an early stage. Sooner or later, the scientists might discover some facts that would explain how life is formed. Humans will know the secret of the space in the near time. I wish I could live longer so that the technology would be highly advanced that it would allow me to travel through space. Space, I love you. Feeling groovy.

Not to downplay the research but didn't Carl Sagan conduct similar experiments back in the 70s? I recall him mentioning in one of his books (maybe Pale Blue Dot?) his hypothesis that Titan's atmosphere was similar to the early Earth's and describing the experiments.

Absolutely. I was hoping the new research would shed light on the spectral distribution of what we see on the surface of Titan, but this does not appear to be the case.

Incidently, the atmosphere of Titan is much 'cleaner' than a smoggy day in LA - we cannot see through the haze because the atmosphere is so thick and dense, not because it is laced with large quantities of smoggy organics. T

What a lousy press release on the part of NASA! They present us with an absolutely exciting hypothesis, but not even the tiniest morsel of real information. This is a news release of a group who has been simulating the atmospheric chemistry of Titan and what may have been the atmosphere of early earth that led to life itself, and yet they didn't have one word to say about what those chemical reactions are, and how do the two atmospheres differ.

Are they so arrogant they think we couldn't understand it? What is the point of tantalizing us with this press release if they didn't intend to give us any real news, any details of any use at all? Shame on you NASA. Perhaps it is the fault of whoever wrote up the press release for you must have been someone with only a grade school education who didn't really understand what he/she was writting about. I would prefer no press release at all to this crap!

I thought there was a paucity of information in this release also. So I searched for the paper. The title came up, but no copy. So I contacted the author. Guess what, not released as of last week. Keep an eye on
