NASA’s “Alien Life” Lives in California, Eats Arsenic
Posted in: NASA, science, Space Tech, Today's ChiliYou know this week’s to-do about the discovery of extra terrestrial that was supposed to be announced at today’s press conference? Well, after a build up, disappointment was really inevitable, right?
NASA sent out a note to the press yesterday announcing that it would,
[H]old a news conference at 11 a.m. PST 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.
Naturally, the press ran with it, declaring that the organization had finally discovered alien life. The real announcement, however, was decidedly less sexy than that. The organization was actually referring to life right here on earth.
Scientists managed to “train” bacteria from California’s alkaline Mono Lake to subsist on arsenic, eventually trading its phosphorus atoms for that material. So, how does this relate to, you know, space?
Says astronomer Dimitar Sasselov of the discovery,
There is basic mystery, when you look at life. Nature only uses a restrictive set of molecules and chemical reactions out of many thousands available. This is our first glimmer that maybe there are other options.
Options like delicious arsenic, apparently.
