Document Summary
Reber detected strong radio emissions from sources in the constellations. Sagittarius is the galactic nucleus and cassiopeia is a supernova remnant, Cyg a was hard to categorize speed of 14,000 km/s. A galaxy associated with cyg a is very dim and the redshift corresponds to a. 17-1 quasars look like stars but have huge redshifts o o. 3c 48 and 3c 273 had a series of emission lines that no body could identify and looked nothing like a star"s blackbody spectrum. The h spectral lines were found at much longer wavelengths than usual o. Stars cannot move extremely fast relative to the sun without soon escaping. Subjected to a substantial redshift from the galaxy the speed of light. Schmidt concluded that 3c 272 is not a nearby star o. The redshift of 3c 273 corresponds to a speed away from us at almost 16% According to hubble law, this redshift implies a distance of 2 billion ly o.
