Alt text:
If you live in Los Angeles (around 33°52'N, roughly the latitude of Hermosa Beach) the black hole in V404 Cygni passes over you each day. On Christmas Day it will be directly overhead around 2pm.
I have read a short story about a world with like 9 suns and 3 moons. It's day all the time, except once every 2000 years, when there is a total solar eclipse. So every 2000 years society falls into chaos, most of the population kills themselves and only rich people, who can afford enough candles/fire or people who are passed out drunk survive the eclipse. At the time the story takes place one astronomer/scientist notices the pattern in their history and like predicts it or something.
Sadly I do not know the link. If anyone recognizes the story I would love to read it again.
It's called Nightfall, it's my favorite Asimov short story.
Thank you!
