Key Science
The VLA is a multi-purpose instrument designed to allow investigations of many astronomical objects, including radio galaxies, quasars, pulsars, supernova remnants, gamma ray bursts, radio-emitting stars, the sun and planets, astrophysical masers, black holes, and the hydrogen gas that constitutes a large portion of the Milky Way galaxy as well as external galaxies. In 1989 the VLA was used to receive radio communications from the Voyager 2 spacecraft as it flew by Neptune. It is not, despite depictions in popular culture, used to assist in the Search for Extra-Terrestrial Intelligence (SETI).

Famous quotes containing the words key and/or science:
“The key to the age may be this, or that, or the other, as the young orators describe; the key to all ages is—Imbecility: imbecility in the vast majority of men, at all times, and even in heroes, in all but certain eminent moments: victims of gravity, customs and fear. This gives force to the strong,—that the multitude have no habit of self-reliance or original action.”
—Ralph Waldo Emerson (1803–1882)
“Science without religion is lame, religion without science is blind.”
—Albert Einstein (1879–1955)
