Using the Very Long Baseline Array, researchers have conducted a detailed survey of young stellar objects within the Orion complex to map its three-dimensional structure with unprecedented precision. By detecting 216 compact radio sources and tracking the movement of 58 of them over multiple epochs, the study successfully measured their distances and motions. The findings reveal that the Orion complex spans distances from 380 to 440 parsecs, providing specific mean distances for key regions s...
