The True Scale of the Orion Arm... And How Small We Really Are

The Orion Arm is our home in the Milky Way — but its true scale is almost impossible to comprehend. In this cinematic space documentary, we journey from Earth beyond the Solar System, through the Orion Arm, across the Milky Way, and toward the largest structures in the observable universe. Along the way, we explore the Solar System, Sagittarius Arm, Perseus Arm, the galactic center, Andromeda, the Local Group, the cosmic web, and the observable universe itself. We also ask some of astronomy’s biggest questions: How large is the Orion Arm? Where is our Solar System inside the Milky Way? Could humanity ever cross it? How many planets may exist around us? And why does space seem so silent? Earth. The Solar System. The Orion Arm. The Milky Way. The universe. The farther we travel... the smaller we become.
