I am not amused.

Sun and Earth relative size and distance.
For relative size and shape comparisons, remember this simple visualizing exercise: The Sun is an 8 inch bowling ball and the Earth is the size of a peppercorn placed 26 yards (78 feet) away!

“I feel big, because my atoms came from those stars.”
The most amazing fact about the Universe ~ Neil deGrasse Tyson
Astronomers unveil new images of a small sliver of the night sky after piecing together 10 years of Hubble space telescope images. The Hubble eXtreme Deep Field is the deepest view yet, adding 5,500 galaxies and showing celestial objects formed 500m years after the universe’s birth

“Look North of the Big Dipper”: A Tiny Field of View Yields 50,000 Galaxies
For over a decade astronomers have been probing a region of the northern sky, not far from the handle of the Big Dipper, that is relatively free of bright stars and the diffuse glow of the Milky Way. The scientists want to take advantage of the clarity of the sky there to peer beyond our galaxy to study remote galaxies in the distant universe. This region, about half the angular size of the full moon, is now known to have over 50,000 galaxies.

50,000 galaxies X 300,000,000,000 stars/galaxy = 15,000,000,000,000,000 stars. Wow. Considering that there may be 100 million habitable environments per galaxy, that would mean that within the small region the size of a full moon in our sky close to the handle of the Big Dipper, there may be 5 trillion places humanity could go to get away from the Republicans.

Two Black Holes Dancing in 3C 75
At the center of galaxy 3C 75 (300 million light-years from us) two co-orbiting supermassive black holes separated by 25,000 light-years are bound together by gravity in a binary system. The jets’ consistent swept back appearance are most likely due to their common motion as they speed through the hot cluster gas at 1200 kilometers per second, surrounded by multimillion degree x-ray emitting gas and blasting out jets of relativistic particles.
When I need humility, I can think of this.
