Two reasons I like Astronomy Pictures of the Day (APOD): images are shown that I've never seen (or imagined) and would be unlikely to see and for the "short courses" APOD provides in the explainers below the image of the day.

You may already know the explanation which only adds to the lovely image

I'm grateful for the skywatchers and shooters who take these images and share them with us.
