Explanation:
The explosion is over but the consequences continue.   
  
About eleven thousand years ago a star in the constellation of   
Vela could be seen  
to   
explode,   
creating a strange point of light briefly visible to humans living near the beginning  
of   
recorded history.   
  
The outer layers of the star crashed into the   
interstellar medium, driving a   
shock wave that is still visible today.   
  
A roughly spherical, expanding shock wave is   
visible in X-rays.  
  
The   
above image   
captures some of that filamentary and gigantic shock in   
visible light.  
  
As gas flies away from the detonated star, it   
decays and reacts with the interstellar medium,   
producing light in many different colors and energy bands.  
  
Remaining at the center of the   
Vela Supernova Remnant is a   
pulsar, a star as dense as nuclear matter that rotates completely around   
more than ten times in a single second.
