(DESCRIPTION) 
 Text, Somewhere in the universe, a star explodes. 


A bright white star goes supernova. A cloud of dust and gas expands outward. 


Text, The explosion sends a shock wave speeding into the cosmos. 


Not too far away, the shock wave slams into a cloud of gas and dust, pressing and squeezing the cloud's contents together. 


The shockwave compresses a red cloud of dust. 


Text, Clumps of material pull together and under the influence of gravity become ever and ever tighter. 


A bright spot appears in the red cloud and grows brighter. 


Text, Eventually these clumps become so dense and hot that hydrogen atoms start to fuse together. 


Several more bright spots appear. 


Text, This fusion process releases an enormous amount of light and heat. 


The bright spots grow intensely bright. 


Text, And from one star's death, other stars are born.
