Reply to comment by dbrodbeck in Do crickets respond to TV’s and video audio, with their own sounds? by Bony_Geese
Playback experiments are how we've determined that prairie dogs have a pretty sophisticated language system that can specifically reference individuals within a group ('a name') and provide relevant information about abstract concepts such as color, direction, distance or friendly/dangerous.
We obvs can't speak prairie dog, but we can predict responses to some sounds for some groups of prairie dogs. Oh, yeah, they also apparently have dialects and proper different languages as different groups can't talk to each other.

Reply to comment by the_fungible_man in The vast majority of the 150-400 billion stars in the Milky Way haven't been directly detected. Alpha Centauri is the nearest known star to Sol. What is the probability that there are nearer stars that remain undiscovered? by [deleted]
The Centauri Solar Cluster has a high visual magnitude because it's a triple system where Proxima is the smallest of the three suns orbiting the barycenter. Proxima contributes very little light to that high visual magnitude, it's all mostly αCenA and αCenB, the other two stars in the system. A and B both together make it the third brightest star in the sky.

Nope. We aren't even sure it's there, we're just pretty sure.
