Definitions
from The American Heritage® Dictionary of the English Language, 5th Edition.
- noun 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.

qms commented on the word blazar
Some planets are lit by a quasar
And tonier 'hoods by a blazar,
But I, being done right
By moderate sunlight,
Am fond of our shabby old daystar.

When a black hole generates a brilliant jet of radiation, and that jet is aimed directly at Earth, scientists call the galaxy a “blazar.” -- July 12, 2018 Washington Post
