	National Park Service: Astronomy and Astrophysics (Allegheny Observatory)
		The Allegheny Observatory at the University of Pittsburgh is significant because of its association with the careers of astronomers Samuel Pierpont Langley (1834-1906), James Edward Keeler (1857-1900), and telescope maker John Alfred Brashear (1840-1920).
		Langley was professor of astronomy and physics at the University from 1867 to 1887 and director of the Allegheny Observatory.
		In 1867 the Allegeheny Observatory was transferred to the Western University of Pennsylvania, the forerunner of the University of Pittsburgh.

	The Allegheny Observatory
		The Allegheny Observatory was created by a group of civic-minded citizens of old Allegheny who formed the Allegheny Telescope Association in 1859.
		Because of the Observatory, the hill came to be called Observatory Hill, and, between 1890 and 1908, also became the campus of the Western University of Pennsylvania, now the University of Pittsburgh.
		Three other American observatories co-operated by focusing their telescopes on that star the night of May 27 and catching its light in a photo-electric cell, which transformed the beam into electricity which was transmitted to Chicago.

	Allegheny Observatory is put out to pasture
		Recently, the observatory laid off Tim Persinger, its chief technician, and Tom Reiland, the chief observer whose nighttime inspection of the skies compiled the data from which scientists like Gatewood deduced the presence of new bodies in the universe.
		In 1867, the observatory was donated to the Western University of Pennsylvania, forerunner to the University of Pittsburgh.
		One of the major discoveries made by the Allegheny Observatory in the late 1895 was that Saturn's rings, once thought to be solid, were made up of billions of particles held in place by the planet's gravity.

	Allegheny Observatory
		The observatory of the University of Pittsburgh, located in Riverview Park, Pennsylvania, 10 miles northeast of the main university campus.
		For most of the twentieth century, this facility has specialized in astrometric observations and its primary research goal continues to be high-precision astrometry, particularly as applied to extrasolar planets.
		Allegheny's main instruments are the Thaw Memorial 0.76-meter (30-inch) refractor, constructed in 1914 and used in the work leading to Gatewood's discovery, and the James E. Keeler 30-inch reflector, built in 1906 and also used for astrometric research.

	On the Allegheny System of Electric Time Signals (1873)
		In this, the only arrangements described are those in use at the Allegheny Observatory, with which the writer has become familiar from the responsibility of their initiation and superintendence.
		The observatory is on the summit of the ascent, on the northern side of the valley of the Ohio, about two miles in a direct line from the offices of the Western Union Telegraph Company in Pittsburg, and rather more from those of the Pennsylvania Central, and Pittsburg, Fort Wayne, and Chicago roads.
		The watchmakers and jewelers are in permanent telegraphic connection with the observatory by a wire which is devoted to their use--but distant cities, such as Chicago or Philadelphia, can be reached only by the wires of the telegraph or railroad companies which are too valuable to be exclusively employed for this purpose.

	The 360 Photo of the Week
		Located four miles north of downtown Pittsburgh in Riverview Park, The Allegheny Observatory is an important astronomical research institution owned and operated by the University of Pittsburgh.
		The primary goal at the Observatory is research - specifically, high-precision astronomy - including extra-solar planet detection and the characterization of planetary systems.
		The Observatory is home to three telescopes (one for each dome), one of which aided Observatory director Dr. George D. Gatewood in his preliminary finding of Lalande 21185, quite possibly a detection of another planetary system consisting of two Jupiter-like objects.
