Because this light is less absorbed by dust than visible light, you could peer into the center of our Milky Way Galaxy. The stars there are normally hidden from direct view by the interstellar dust clouds which line the Galactic plane. ... Interplanetary dust , which tends to lie along the plane of our own solar system, scatters sunlight and emits radiation at these wavelengths too. ...
