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 in, presence and/or space:
“The Virgin filled so enormous a space in the life and thought of the time that one stands now helpless before the mass of testimony to her direct action and constant presence in every moment and form of the illusion which men thought they thought their existence.”
—Henry Brooks Adams (1838–1918)
“The presence of a grandparent confirms that parents were, indeed, little once, too, and that people who are little can grow to be big, can become parents, and one day even have grandchildren of their own. So often we think of grandparents as belonging to the past; but in this important way, grandparents, for young children, belong to the future.”
—Fred Rogers (20th century)
“The merit of those who fill a space in the world’s history, who are borne forward, as it were, by the weight of thousands whom they lead, shed a perfume less sweet than do the sacrifices of private virtue.”
—Ralph Waldo Emerson (1803–1882)
