I conclude, therefore, that this star is not some kind of comet or a fiery meteor... but that it is a star shining in the firmament itself one that has never previously been seen before our time, in any age since the beginning of the world.

There are some galaxies that not only teach us things but are just gorgeously beautiful to look at. My favorite example is the Antenne, which is a pair of colliding galaxies.
A supernova is one of the most powerful explosions in the universe. It's so luminous, it can be seen across billions of light years. It releases as much energy in an instant as our sun will produce over its 10-billion-year lifetime.
One naked star has waded through The purple shallows of the night, And faltering as falls the dew It drips its misty light.
