Nasa telescopes capture image of galaxy resembling eye

• The three telescopes were able to create the image of the galaxy NGC 4151 showing gas interacting with the growing black hole at its centre.
  
  
• The white spot which looks like the eye’s pupil is the black hole and the red circumference is hydrogen.
  
  
• The blue is created by X-rays which scientists are studying to understand how such black holes interact with the gas around them.
  
  
• NGC 4151 is one of the nearest galaxies which contains an actively growing black hole.
  
  
• It offers one of the best chances of studying the interaction between an active supermassive black hole and the surrounding gas of its host galaxy
