(DESCRIPTION) 
 Text, Did You Know? Recycling in the Universe 

The Sun (Solar Dynamics Observatory) The Sun is made of recycled matter from other stars. 

The Sun formed billions of years after the big bang 

Most of the atoms that make up the Sun formed during the big bang. 

Some have formed inside the Sun itself. 

A formation of purples and teals. Text, Supernova Remnant W 498 (Chandra X-ray Observatory, Palomar Observatory, Very Large Array). But the Sun also contains elements that could have formed only inside the cores of earlier stars. 

Other elements in the Sun form only when more massive stars explode or collide. 

Many generations of stars must have lived - and died - before the Sun. 

The Sun is made of the recycled remains of its ancestors.
