Astronomers create most detailed 3D map of Milky Way dust

US-based Berkeley Lab researchers have developed the highest resolution 3D map of space dust in the Milky Way. The mapping was done by a 1.4-gigapixel camera combined with infrared spectroscopy. Dust in Earth's sky contributes to the reddish sunsets, similarly, cosmic dust can make distant celestial objects appear redder affecting calculations, researchers said, which led them to map the galaxy.
