NASA เตรียมแถลงการค้นพบสิ่งมีชีวิตนอกโลก

ในวันที่ 2 ธันวาคม นาซ่าจะออกมาแถลงข่าวอย่างเป็นทางการในการค้นพบ
สิ่งที่เจอน่าจะเป็นแบคทีเรียที่สามารถสังเคราะห์แสงหรืออย่างไรนี่แหละครับ

NASA Sets News Conference on Astrobiology Discovery; Science Journal Has Embargoed Details Until 2 p.m. EST On Dec. 2


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 news conference will be held at the NASA Headquarters auditorium at 300 E St. SW, in Washington. It will be broadcast live on NASA Television and streamed on the agency's website at http://www.nasa.gov.

Participants are:
- Mary Voytek, director, Astrobiology Program, NASA Headquarters, Washington
- Felisa Wolfe-Simon, NASA astrobiology research fellow, U.S. Geological Survey, Menlo Park, Calif.
- Pamela Conrad, astrobiologist, NASA's Goddard Space Flight Center, Greenbelt, Md.
- Steven Benner, distinguished fellow, Foundation for Applied Molecular Evolution, Gainesville, Fla.
- James Elser, professor, Arizona State University, Tempe

Media representatives may attend the conference or ask questions by phone or from participating NASA locations. To obtain dial-in information, journalists must send their name, affiliation and telephone number to Steve Cole at stephen.e.cole@nasa.gov or call 202-358-0918 by noon Dec. 2.

Has NASA discovered extraterrestrial life?

Here's a curious press release from NASA:

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.
​

I did a little research on the news conference participants and found:
1. Pamela Conrad (a geobiologist) was the primary author of a 2009 paper on geology and life on Mars
2. Felisa Wolfe-Simon (an oceanographer) has written extensively on photosynthesis using arsenic recently (she worked on the team mentioned in this article)
3. Steven Benner (a biologist) is on the "Titan Team" at the Jet Propulsion Laboratory; they're looking at Titan (Saturn's largest moon) as an early-Earth-like chemical environment. This is likely related to the Cassini mission.
4. James Elser (an ecologist) is involved with a NASA-funded astrobiology program called Follow the Elements, which emphasizes looking at the chemistry of environments where life evolves (and not just looking at water or carbon or oxygen).
So, if I had to guess at what NASA is going to reveal on Thursday, I'd say that they've discovered arsenic on Titan and maybe even detected chemical evidence of bacteria utilizing it for photosynthesis (by following the elements). Or something like that. (thx, sippey)
Update: According to Alexis Madrigal, the answer to the hyperbolic question in the headline is "no".

I'm sad to quell some of the @kottke-induced excitement about possible extraterrestrial life. I've seen the Science paper. It's not that.
