Explanation:
An  
energetic jet from the core of  
giant elliptical galaxy M87 stretches outward for 5,000 light-years.  
  
This monstrous jet  
appears  
in the panels above   
to be a knotted and irregular structure, detected  
across the spectrum, from  
x-ray to optical to  
radio wavelengths.  
  
In all these bands,  
the observed emission is likely created as high energy  
electrons spiral along magnetic field lines, so called  
  
synchrotron radiation.  
  
But what powers this cosmic blowtorch?  
  
Ultimately, the jet is thought to be produced  
as matter near the center of M87  
swirls toward a spinning, supermassive black hole.  
  
Strong electromagnetic forces are generated and eject material  
away from  
the black hole along  
the axis of rotation in a narrow jet.  
  
Galaxy M87  
is about 50 million light-years away and reigns as  
the large central elliptical galaxy in the  
Virgo  
cluster.
