Just over 3 years ago, I moved to a farm where I can see the Milky Way from my back door. Despite being an astronomer, I've never had that kind of personal access to a dark sky before, and it totally changed my relationship with the sky.

I have always loved looking at the stars, but now I also feel a shared ownership of this natural resource with all of humanity, past, present, and future. This is my sky! Our sky! Our human history!

@sundogplanets I once heard a theory that Starlink could set us back in an important way, by making it harder to detect potentially threatening asteroids. I've always wondered if there's any truth to this. NASA just took humanity forward by a giant step by proving it can protect the planet from this particular world-ending disaster. It only works if we can detect it though, and Starlink is setting us back again.
