Astronomy

More than 70 years ago, astronomers were doing a sky survey when three bright stars they just saw disappeared, never to be seen again.

NASA has hit a significant problem. Two fasteners are stuck.

APOD October 22, 2023: Ghost Aurora over Canada

What does this aurora look like to you? While braving the cold to watch the skies above northern Canada early one morning in 2013, a most unusual aurora appeared. The aurora definitely appeared to be shaped like something, but what? Two ghostly possibilities recorded by the astrophotographer were "witch" and "goddess of dawn", but please feel free to suggest your own Halloween-enhanced impressions. Regardless of fantastical pareidolic interpretations, the pictured aurora had a typical green color and was surely caused by the scientifically commonplace action of high-energy particles from space interacting with oxygen in Earth's upper atmosphere. In the image foreground, at the bottom, is a frozen Alexandra Falls, while evergreen trees cross the middle.

So, I was looking at this:

https://en.wikipedia.org/wiki/Habitability_of_binary_star_systems

And I want to write a sci-fi story about Non-circumbinary planet in a binary system. (The "S type" shown on that wiki page.)

And although I'm not going hardcore for the "hard" sci-fi, I want to get at least a vaguely plausible idea of how day/night and year cycles might go for such a planet. If only so I can get an idea of how I need to set up my calendar, and brainstorm on how animal/plantlife might evolve differently if the day/night cycle and seasonal cycle is different enough from Earth.

Are there any tools out there where I can either find an existing binary star system out there and put a hypothetical planet around one of them and get a visual of how sunlight from the two stars might play out over the planet circling one of them, or where I can just straight-up plop stellar/planetary masses down and it'll let me play with orbits and such?

Back in the day there wasn't, but I feel like someone might have evolved some sort of toy that'll let me do this when I wasn't looking. I just don't know where to start.
