This artist's concept show how it is possible for a single collection of particles, which share a common family of orbits around the Sun, to produce the appearance of identical bands on either side of the zodical or ecliptic plane. The bands were discovered in data from the Infrared Astronomical Satellite. Also illustrated is the concept of a comet/asteroid collision which could have created a cloud of debris. The dust cloud, as depicted here, has the orbital parameters needed to produce the band structure observed by IRAS. ARC-1983-A83-0768-3

Milky way - This image of the center of our galaxy was produced from observtons made by the Infrared Astronomical Satellite (IRAS). The infrared telescope carried by IRAS sees through the dust and gas that obscures stars and other objects when viewed by optical telescopes. The bulge in the band is the center of the galaxy. The knots and blobs scattered along the band are giant clouds of interstellar gas and dust heated by nearby stars. Some are wrmed by newly formed stars in the surrounding cloud and some are heated by nearby massive, hot, blue stars tens of thousands of times brighter than our Sun. ARC-1983-A83-0768-1

This artist's concept illustrates the ring of material discovered by the Infrared Astronomical Satellite around the star Vega. IRAS scientists believe the material probably consists of dust and small objects resembling meteors. As depicted here, the ring of particles is thin enough toallow light from distant stars to shine through. The plane of the Milky Way is to the right. ARC-1983-AC83-0768-4
