Life's ingredients circle Sun-like star
http://www.newscientistspace.com/article.ns?id=dn8507

The first evidence that some of the basic organic building blocks of life can exist in an Earth-like orbit around a young Sun-like star has been provided by NASA's Spitzer Space Telescope.

Spitzer took infrared spectrograms of 100 very young stars in a nearby stellar nursery, a huge cloud of dust and gas 375 light years away in the constellation Ophiuchus. And one of those stars showed signs of the organic molecules, acetylene and hydrogen cyanide.

These gases, when combined with water, can form several different amino acids. These are needed to form proteins, as well as one of the four chemical letters, or bases, in DNA, called adenine.

The detection supports the widely held theory that many of the molecular building blocks of life were present in the solar system even before planets formed, thus assisting the initial formation of complex organic molecules and the start of life itself.

1. I will be delighted the first time exploration
turns up life on another planet, satellite, asteroid, or what have you, and yes, bacterial life will be sufficient.

Anything to shoot the fundies down on their egocentrism that states this is the only life in an otherwise dead universe.

2. But wait, Man has dominion over the beasts
Anything to shoot the fundies down on their egocentrism that states this is the only life in an otherwise dead universe.

Until a causasian-looking humanoid alien steps off his saucer with a copy of the King James, fundies won't acknowledge non-terrestrial life as anything more than dumb animals fit for subjugation.
