Won’t happen for 20-40 million years. I don’t plan to stay up to watch.

Paid to predict stuff that may or may not happen in twenty million years.

Nice work, if you can get it.

Will it nine, seven or just the one ring?

And I just pray I’ll wake upon the morn. How insignificant. Either, compared to the glory that commands it. Interesting to ponder though.

mars will be more happy with a ring than an impact from the thing...........

It’s an abandoned starship.

If the galaxy even lasts another 20-40 million years.

Once our own Sun has consumed all the hydrogen fuel in its core, it too will reach the end of its life. Astronomers estimate this to be a short 7 billion years from now. For a few million years, it will expand into a red giant, puffing away its outer layers. Then it’ll collapse down into a white dwarf and slowly cool down to the background temperature of the Universe.

I’m sure you know that some other stars explode when they die. They also run out of fuel in their core, but instead of becoming a red giant, they detonate in a fraction of a second as a supernova.

So, what’s the big difference between stars like our Sun and the stars that can explode as supernovae?

Mass. That’s it.

Phobos survived a giant impact early in its history,

Or it was arc pitted when zapped from the Martian surface.
