The New Horizons Spacecraft Just Helped Make First Stereoscopic Image Of A Star's Location

Much of astronomy is based around measuring the distances to celestial bodies, and the distances are all rooted in a technique called stellar parallax. This has been used since the 19th century to measure the distances to stars, and all measurements of interstellar and intergalactic distances are based on the measurement of the tiny wobble in a star's apparent position.
The problem is, despite it being a fundamental technique at the core of astronomy, nobody has ever been able to make a simple, obvious demonstration of it, until now.
