Orientation of the Central Engine and Its Jets

Description
Orientation of the Central Engine and Its Jets
BL Lacertae objects, quasars, and double-radio sources appear to be the same type of object viewed from different directions. If one of the jets is aimed
almost directly at Earth, we see a BL Lac object. If the jet is somewhat tilted to our line of sight, we see a quasar. If it is tilted farther, we see an active
galaxy. If the jets are nearly perpendicular to our line of sight, we see a double-radio source.
