  • Astronomers from Italy have captured the first image of an 'invisible galaxy' using Albert Einstein's general theory of relativity.
  • The galaxy is termed invisible because the light emitted couldn’t be seen from the earth.
  • Einstein's theory states that a mass distribution could act as a gravitational lens that bends light, and a team of astronomers from Italy used this idea to see the 'background' of the invisible galaxy.
  • The 'invisible galaxy' forms stars at about 1000 times the rate of the Milky Way.
  • And it is also very young - considering the big bang happened 13.8 billion years ago and formed two billion years later. 
  • The team used the ALMA (Atacama Large Millimeter/submillimeter Array) telescope in Chile to capture this unbelievable observation.
