Dust is prevalent in the universe. Around the sun, in the paths of planets, in beautiful nebualas, dust is everywhere. Dust also accumulates in strange places. How strange?

Nebulas are made largely of dust, and it is in nebulas where stars are born. Dust also moves around the solar system, and in the universe in ordered patterns.
