Rumor Roundup: Has NASA Discovered Alien Life?

Will we find evidence of a real-life E.T. in the very near future?
A NASA press release announcing "an astrobiology finding" -- something that will impact the search for extraterrestrial life -- has sent shockwaves through the blogosphere.

The press release simply announces an event, set for Thursday at 2 p.m. EST, to discuss an astrobiology discovery "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.

And the concept of NASA discussing alien life has everyone a-Twitter. Gawker, PC World, New Scientist and others have all speculated about the news -- even suggesting that the space agency may reveal that E.T. has finally arrived.

The reality may be less dramatic, though still intriguing: Based on the background of the four conference participants NASA cites, the announcement will probably concern lifeforms that live off of poisonous arsenic. Popular blogger Jason Kottke and others have concluded that the announcement will tie into the quest for life on Saturn's moon Titan.

"I'd say that they've discovered arsenic on Titan and maybe even detected chemical evidence of bacteria utilizing it for photosynthesis," Kottke theorizes, a hypothesis short of actually confirming alien life.

He notes that geobiologist Pamela Conrad was the primary author of a 2009 paper on geology and life on Mars, while oceanographer Felisa Wolfe-Simon has written extensively on photosynthesis using arsenic. Biologist Steven Benner is on the "Titan Team" at NASA's Jet Propulsion Laboratory; they're looking at Saturn's largest moon as an early-Earth-like chemical environment. And ecologist James Elser is involved with a NASA-funded astrobiology program called Follow the Elements, which studies the chemistry of environments where life evolves, not just water, carbon or oxygen.

Despite the hype and rumors, Phil Plait of Discover Magazine urged rational calm, noting that an announcement of the discovery of extraterrestrial life "seems really unlikely." Plait called overreactions par for the course, citing a June press release about the lack of acetlyne in Titan’s atmosphere "that sparked vast speculation."

"Even though the press release was clear enough, it was misleadingly reported as NASA finding sings of life on Titan," Plait wrote.

Forbes blogger Brian Caulfield agreed, noting that "Thursday’s news is probably a big deal" but "probably just not that big a deal."

Of course, there is always the chance that NASA has discovered alien life -- right? We'll know for sure tomorrow. Stick with FoxNews.com for complete coverage of NASA's news conference Thursday at 2 p.m. EST and be sure to check out our Twitter feed for real-time updates.

A lot of people are curious. It may also be evidence of Earth like planets as well.

It's been confirmed: NASA found a type of life form on Earth.

At their conference today, NASA scientist Felisa Wolfe Simon will announce that they have found a bacteria whose DNA is completely alien to what we know today. Instead of using phosphorus, the bacteria uses arsenic. All life on Earth is made of six components: carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur. Every being, from the smallest amoeba to the largest whale, share the same life stream. Our DNA blocks are all the same.

But not this one. This one is completely different. Discovered in the poisonous Mono Lake, California, this bacteria is made of arsenic, something that was thought to be completely impossible. While she and other scientists theorized that this could be possible, this is the first discovery. The implications of this discovery are enormous to our understanding of life itself and the possibility of finding beings in other planets that don't have to be like planet Earth.

Very cool! It opens up wider what we define as 'life'.

Even the Doctor has to teach kids how to cross a busy road.
