Though this 1970s-era spacecraft is pretty far out there by now and still sending back information, it’ll never be able to take a snapshot of the Solar System. Or the Milky Way. And definitely not the entire observable universe. But with a little math and artistic prowess, we can cobble together what we may look like from way, way, way out there.

The zone that defines where light can escape and where it can never return is known as the event horizon. But what actually happens at this point of no return? If you crossed it, what would you see? PBS SpaceTime uses a little-known physics tool to explore these questions.
