 (blā′zär′, -sär′, -zər, -sər)
A compact, extremely bright, active galactic nucleus characterized by strong and rapid changes in the intensity of electromagnetic radiation emitted over a very broad range of frequencies ranging from radio waves to gamma rays. Although the source of blazar energy is the material surrounding a super-massive black hole at the galaxy center, much of the blazar luminosity originates in powerful jets of material moving along the line of sight toward Earth at near light speed.

[Coined by Edward A. Spiegel (1931-2010), American astronomer, as a blend (influenced by blaze) of BL Lac object, a type of blazar once thought to be a variable star (after BL Lacertae, a blazar in Lacerta), and quasar.]
