Number 59 on my mission101 and my last little essay...for this time around anyway:)

Active Galaxies: Black Holes, Blazars, and Quasars
All images were snagged, with some thought and care, and even with some credit, from Google Images.

        Digression One: The Milky Way Galaxy, and its closest neighbor in our local group, the Andromeda Galaxy, will only be mentioned here and there in this the last of my little essays because they are both examples of a Normal Galaxy, which is one where:
       1) its total energy output equals the total emissions of all its stars and
       2) its centrally located supermassive black hole has very little gas for capture and so, hasn’t, and probably won’t, form a Quasar or a Blazer at its center and as cool as a normal galaxy is, it is nonetheless a subject best left for another time.

In summation
                And so, to quote one source (I forget where…sorry)
 ‘Quasars have been so elusive and mysterious that the hunt to define them would have taxed even the superior analytical skills of detective Sherlock Holmes’ (way to tie-in, am I right?)
                I don’t know about how right I am, but I certainly am nearly done. With each of these three little essays, I started out thinking I was researching one thing and, as I learned, I quickly, or sometimes not so quickly, realized I was actually researching something quite different. The way of life and just as it should be.
