... the blast signatures of a detonated supernova and that of a nuclear bomb are identical. ↗

Pluto is currently designated a 'plutoid', and if you think that sounds ok, try adding 'oid' to your name. Her? She's a Susanoid. Hi, I'm a Davoid. It's demoralising. ↗

Recognize that the very molecules that make up your body, the atoms that construct the molecules, are traceable to the crucibles that were once the centers of high mass stars that exploded their chemically rich guts into the galaxy, enriching pristine gas clouds with the chemistry of life. So that we are all connected to each other biologically, to the earth chemically and to the rest of the universe atomically. That’s kinda cool! That makes me smile and I actually feel quite large at the end of that. It’s not that we are better than the universe, we are part of the universe. We are in the universe and the universe is in us. ↗

Unlike what you may be told in other sectors of life, when observing the universe, size does matter, which often leads to polite ‘telescope envy’ at gatherings of amateur astronomers. ↗

They say that even the brightest star won't shine forever. But in fact, the brightest star would live the shortest amount of time. Feel free to extract whatever life lesson you want from that. ↗

The bright sun was extinguish'd, and the stars Did wander darkling in the eternal space. ↗

The near side of a galaxy is tens of thousands of light-years closer to us than the far side; thus we see the front as it was tens of thousands of years before the back. But typical events in galactic dynamics occupy tens of millions of years, so the error in thinking of an image of a galaxy as frozen in one moment of time is small. ↗
