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.
