"Of all the dispositions and habits which lead to political prosperity, religion and morality are indispensable supports. In vain would that man claim tribute to patriotism who should labor to subvert these great pillars of human happiness -- these firmest props of the duties of men and citizens. . . . reason and experience both forbid us to expect that national morality can prevail in exclusion of religious principles."
George Washington

"Only a virtuous people are capable of freedom. As nations become more corrupt and vicious, they have more need of masters."

Why would this be 4 separate images rather than a continuous ring?

The gravity of the intervening galaxy isn't uniform.

Not sure how it works but if there were a ringed supernova, that'd make them have to rethink all this stuff from the beginning.

I am sure it's got something to do with how the image was taken that it would give them four different looks and magnify it too.

That makes sense.

Nothing should make a man happier than knowing his government couldn't care less about him.
I'd rather lose defending the constitution than win at its expense.
