In 1963, Maarten Schmidt of the California Institute ofTechnology found the most distant object that had ever been seen inthe universe so far. Called 3C273, it emitted electromagneticradiation with a power of 2×1013 Suns, or 100 times that of theentire Milky Way galaxy! Schmidt called 3C273 a \"Quasi-StellarRadio Source,\" a name that was soon shortened to \"quasar.\" Sincethen, astronomers have found many quasars, some substantially morepowerful and distant than 3C273. Quasar 3C273 is moving away fromEarth at about speed 0.16c. The Sun is 1.5×1011mfrom Earth andemits energy at a rate of 3.8×1026J/s caused by the conversion of4.3×109kg/s of mass into light and other forms of electromagneticenergy. The Hubble constant is
H=70.8km/sMpc=70.8103m/s3.09×1022m==22.9×10−19s−1
Estimate the mass of 3C273 that is converted to light and otherforms of radiation each minute. By comparison, the mass of Earth is6×1024kg.
