(DESCRIPTION) 
Galaxy of white, brown, and red 


The universe is full of dust 


stars and dust swirl, forming a spiral galaxy 


We see regions and lanes of dust within galaxies. 


Clouds of dust collapse and condense to form stars and planets. 


stars float among clouds 


It even drifts in the spaces between galaxies. 


But where does dust come from? 


Cosmic dust comes from stars. 


Stars spew dust as they grow older. 


And when massive stars explode, they can give off huge amounts of dust. 


This supernova, SN 1987A, was observed giving off enough dust to build 160,000 to 230,000 Earths.
