NASA news conference

Thx OP
- expect it will be the discovery of some unidentified extremophillic microorganism (survives at extremes of temperature/pressure/pH/salt concentration/etc), which shouldn't be too much of a surprise to the scientific community - who will then begin work on isolating its potentially useful enzymes :)

"WASHINGTON -- NASA will hold a news conference at 2 p.m. EST on Thursday, Dec. 2, to discuss an astrobiology finding that will impact the search for evidence of extraterrestrial life. Astrobiology is the study of the origin, evolution, distribution and future of life in the universe...."

The cynic in me writes: Does this not usually mean that they're struggling for some sort of U.S. Gov't funding ?

That's not really cynical, it's a fact of life - any publicity whether it be this or publishing in top peer-reviewed journals usually encourages funding whether it be public sector grants or private funding (and with enzymes of special interest ... the chemical and biopharmaceutical industry should be interested)

From wikipedia:

The atmosphere of Titan is largely composed of nitrogen; minor components lead to the formation of methane and ethane clouds and nitrogen-rich organic smog.


I'd love to know if life there has an electron transport chain and what it would use instead of oxygen?

Any biologists here?

Potentially life there could be using ammonia as an energy source instead of sunlight due to very low intensity that far away. Could there be sulphur in the soil the life combines with the hydrogen instead to make hydrogen sulphide as an energy source?

Could the free hydrogen in the atmosphere then be ionised for some kind of transport chain using the energy from NH3/ H2S?

How else might the free hydrogen in the atmosphere be used instead of oxygen?

Even chemicals like ATP and NADP wouldn't exist without oxygen though. Truly fascinating thought.

****ing hell mate. That has sent shivers down my spine. Would give my right leg for that to be true. :thumbsup:

I'd be really interested to know what the metabolic pathways for a type of respiration with hydrogen are.

Keep your leg on (probably): Has NASA discovered extraterrestrial life?. And if I had 10p for every time someone had come to this Audio-Visual-Technology-based forum and started harping on about the "metabolic pathways for a type of respiration with hydrogen" I'd be 10p richer :)

Sure it isn't a viral for Monsters which is out soon and features a crashed NASA probe filling Mexico with aliens (not the sort that picks fruit either)?

I watched that film recently. It has a serene beauty to it like 'Solaris'. I really enjoyed it. :thumbsup:

One of the senior editors of The Atlantic claims to have read the upcoming NASA brief and he's tweeted that the press conference won't be announcing the discovery of extraterrestrial life.

Twitter / alexismadrigal: I'm sad to quell some of t ...

Hope he is very wrong. Would be so exciting to discover ET life on another body in our solar system.

Still, the panel of specialists NASA has selected to make the announcement certainly have interesting backgrounds.

James Elser - Specialises in studying the chemistry of environments where ecosystems flourish, as well as speculating about exotic environments that might support ET life.

“Follow the Elements” Astrobiology at Arizona State University

Benner - Part of Casini mission team comparing Titan's chemistry to primordial Earth.

Conrad - Concerned with potential habitability of other planets, presumably in our SS. Also works on remote sensing life on Mars by studying its geology.

Felisa Wolfe-Simon - Is a geomicrobiologist publishing work concerning the influence microbes have on geological processes.

The fact that Titan, a moon in our very own solar system, could potentially harbour life for me is a given that life exists elsewhere.

Everything is made up from the same matter that existed in the first micro-seconds of the big bang, and because everything is made up from the same matter everything has an equal chance of life, to evolve and exist.

It's big out there, really big, too big for us to be naive enough to think we are alone.

I read elsewhere that a NASA employee tweeted that the announcement tomorrow is nothing exciting. :(
Well not about extra-terrestrial life anyway.

the question is is this life elsewhere intelligent? Theres probably defintiely stuff up there somewhere but is it trying to get off it's but to try and find us like we are it?
