Presence in Space
The detection of glycine in the interstellar medium has been debated. In 2008, the glycine-like molecule aminoacetonitrile was discovered in the Large Molecule Heimat, a giant gas cloud near the galactic center in the constellation Sagittarius by the Max Planck Institute for Radio Astronomy. In 2009, glycine sampled in 2004 from comet Wild 2 by the NASA spacecraft Stardust was confirmed, the first discovery of extraterrestrial glycine. That mission's results bolstered the theory of panspermia, which claims that the "seeds" of life are widespread throughout the universe.

Famous quotes containing the words presence and/or space:
“Really, all things and persons are related to us, but according to our nature, they act on us not at once, but in succession, and we are made aware of their presence one at a time. All persons, all things which we have known, are here present, and many more than we see; the world is full.”
—Ralph Waldo Emerson (1803–1882)
“The peculiarity of sculpture is that it creates a three-dimensional object in space. Painting may strive to give on a two-dimensional plane, the illusion of space, but it is space itself as a perceived quantity that becomes the peculiar concern of the sculptor. We may say that for the painter space is a luxury; for the sculptor it is a necessity.”
—Sir Herbert Read (1893–1968)
