Redshift 4.75 Quasar

While this redshift 4.75 quasar may not be the most distant quasar known, it was first among its high-redshift brethren to be identified by Sloan Digital Sky Survey researchers. This photometric image from September can't reveal the most remarkable feature of the quasar, namely that the Lyman-alpha and Carbon-IV spectral emission peaks are unusually narrow compared to an average quasar.
