KAO was named after the astronomer Gerard P. Kuiper. Carrying a 36-inch reflecting telescope, KAO was a converted C-141 military cargo plane with a 160-foot wingspan. Flying at altitudes of 41,000 to 45,000 feet, above 99 percent of the Earth's infrared-absorbing water vapor, KAO was capable of conducting infrared astronomy. Harvey would have observed from behind the telescope; the telescope was looking out the hole in the roof behind the cockpit. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/KAOflight/KAOflight.dc.xml Thu, 01 Jan 1970 12:00:00 GMT http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/Moseley_Yerkes_Telescope_apf2-08762r/Moseley_Yerkes_Telescope_apf2-08762r.dc.xml The 40-inch refracting telescope at the Yerkes Observatory of the University of Chicago. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/Moseley_Yerkes_Telescope_apf2-08762r/Moseley_Yerkes_Telescope_apf2-08762r.dc.xml Thu, 01 Jan 1970 12:00:00 GMT http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/NASA-COBE/NASA-COBE.dc.xml In 1989, the Cosmic Background Explorer (CoBE) spacecraft was launched into an Earth orbit to make a full sky map of the Cosmic Microwave Background (CMB) radiation. CoBE found very subtle irregularities in the otherwise very uniform CMB, findings that are considered important evidence in support of the Big Bang theory. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/NASA-COBE/NASA-COBE.dc.xml Thu, 01 Jan 1970 12:00:00 GMT http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/NASA-COBE-MAP/NASA-COBE-MAP.dc.xml The final CoBE all-sky map of the apparent fluctuations in the cosmic background, thought to be the seeds of the large scale structure of the Universe. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/NASA-COBE-MAP/NASA-COBE-MAP.dc.xml Thu, 01 Jan 1970 12:00:00 GMT http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/jp2.py/jp2.py.dc.xml Photocopy of a manuscript map showing conferederate defensive fortifications, roads, rivers and names of property owners of Chesterfield County, Virginia, in 1864. Today there is an unincorporated town in eastern Chesterfield County called Moseley, Virginia. Perhaps this town was named after one of Harvey Moseley's ancestors. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/jp2.py/jp2.py.dc.xml Thu, 01 Jan 1970 12:00:00 GMT
