Re: APOD: The Last Days of Venus as the Star... (2022 Jan 06)

Re: APOD: Moons Beyond Rings at Saturn (2022 Jan 04)
I can't imagine any human will EVER visit Saturn, or even Jupiter for that matter - radiation and particles are killers, and what would humans do there anyway? I can't imagine any human will EVER… cross the ocean, explore the Arctic, work in Antarctica, travel into space, visit the Moon, … . But we...

Maybe they’ll finally realize that using highly paid scientists and pilots to clean floors and toilets is not a good idea and the...

I am curious why so much of the text of today’s APOD comes from this page…

Attribution is a good thing, even if the originator volunteers the text for APOD’s use.
