I can’t be the first

I can’t be the first person to arrive at this.

What has been written about the prospect of looking for other artificially lighted planets outside our solar system?

When the dark side of the planet is viewed from space our Earth is covered with lights. Much of Europe, all of the Eastern seaboard of the US (Boston to Washington DC), on the West coast San Francisco to San Diego, Asia and other points on the globe are clearly lighted.

We can’t be the only ones who see this. Could Hubble scan with such a criteria (is it even working any longer)? Wouldn’t this screen out the clearly lifeless planets? Do we only see planets lighted by their own solar systems?

Your humble Ratfish is a layman. I only have questions.

Thank you for your indulgence.
