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.

“I dont think there is anything on earth more wonderful than those wistful incomplete friendships one makes now and then in an hour’s talk.

—John Dos Passos (1896–1970)
“There have been heroes for whom this world seemed expressly prepared, as if creation had at last succeeded; whose daily life was the stuff of which our dreams are made, and whose presence enhanced the beauty and ampleness of Nature herself.”

“For tribal man space was the uncontrollable mystery. For technological man it is time that occupies the same role.”
