www.nasa.gov/home/hqnews/2010/nov/HQ_M10-167_Astrobiology.htmlApparently NASA will be doing a great big announcement about some sort of great astrobiology finding (2 p.m. EST. Thursday, Dec. 2). Panspermia related findings? Lesser forms of life on mars? Something awesome? I don't know, but I sure as hell want to.

They found that guy that slipped off the space station sitting on Mars.  |

They're releasing The Beatles on the moon LOL. You're on a streak! I hope they give us exclusive rights to the actual south pole of the moon </hope> |

This is what is causing all the commotion. Shklee really isn't that bad though, so no reason for alarm.  |

Well, it's still a big finding, it changes the way we understand the structure of living things and it broadens the posible environments that can give origin to life.

It was some weird new bacteria they found in this place called Mono Lake. Dammit, I wanted little green men! No way dude, it's all about the little silver men...Wait, did that sound really really really really really really really gay? |

They discovered the chemical that makes life.. Yeah, that's pretty important.

They discovered that a chemical can replace Phosphorus in the basic structure of living things (sort of, I'm not sure if arsenic fully replaces Phosphorus on all of the bacteria's structure or just in some parts) Kind of FIX'd ;D |

Not quite Lyserg.
They found a bacteria that lives in a toxic lake in California. Since the bacteria lives in the toxic lake it primarily feeds on phosphorous, which is essential to life as it is found in DNA and RNA which make up all life on the planet earth (plant, animal, bacterial, and even viral life). They trained this bacteria to live on arsenic, which is a metalloid and completely non-essential to life. Without the intake of phosphorous, it would normally be assumed that the bacterium would not be able to reproduce properly due to the chemical deficiency. But it was discovered that replacing phosphorous with arsenic the bacterium were capable of adjusting, and no longer needed the phosphorous. Arsenic is similar to phosphorus in that the two elements bond similarly, but the two do have slightly different properties, of which I'm not going to list here.
The point of the matter, we assumed many years ago that planets with life would have to have a dense atmosphere (still true), and that the atmospheres had to be nitrogen rich (not true anymore) and that carbon, phosphorous, and oxygen had to be commonly occurring elements (not true anymore). This has exponential increased the number of planets who could possibly give rise to life.
