Oh, no. It is due to my ignorance about astronomy. I'm strange to this field. I even didn't know what supernova is until I checked the information about it online. Now I've just learned that supernove is the dying star which can be brighter than the living star. Maybe your haiku tries to express such a view: No matter how stars go through all the vicissitude, experiencing the changing fortunes, our earth remains the same. Or maybe I'm completely wrong.
But it is absolutely not your haiku's fault. You know many times a good poem just cries for a proper person to find it, understand it and enjoy it. I can only say that I'm that lucky one who finds and enjoys your haiku--the sunset's adagio, since I'm familiar to the sunset secenary. I still remember when I read Li Qingzhao's poem 落日溶金 at first, I had not very special feeling. However one day when I looked up the sky, while walking on a road by nightfall, I suddenly realized the poem's beauty. My God, the sunset looked so beautiful and gorgeous, and it kept on moving slowly really like the gold melting. What's more, we have a lot of books/videos teaching people how to analyze and enjoy ancient Chinese poetry. So I wrote that your haiku---sunset's adagio is an audi-visual feast. We analyze poetry from time to space, as well as different sensory pleasures, (seeing, hearing, smelling, tasting...)etc. Pitifully I still don't know how to appreciate the beauty of Sabi. When you told us ''the starlight we perceive may be from millions of years ago, I felt happy for a long time. I guess maybe I have understood the beauty of Sabi a little. Thank you again!
