The stars Alpha Centauri (upper left) including A and B, are part of the same trinary star system as Proxima Centauri (circled). These are the three nearest stars to Earth, and they’re located between 4.2 and 4.4 light-years away. From a different location in space that was far enough away from Earth, the nearest among the stars in the field, including Alpha and Proxima Centauri, would appear to shift relative to the background, more distant stars. (WIKIMEDIA COMMONS USER SKATEBIKER)NASA’s New Horizons is the most distant technologically advanced observatory ever. And that makes all the difference.When you look at an object that’s very distant from you, how well can you tell how far away it truly is? Our ability to do this is known as depth perception. Although some of our depth perception arises due to things like relative motions, apparent sizes, texture gradients, and other things you can observe with a single eye, the most universal visual cue comes from our binocular vision: two eyes that are located in different places from one another.The separation between our eyes is key to three-dimensional imaging, or our sense of depth perception. In astronomy, this gets taken to the extreme, as two ...
