[Daily Mail, where America gets its news] ‘Einstein Ring' galaxy captured by the Hubble Space Telescope is more than NINE BILLION years old and was formed as the universe was going through a 'baby boom', scientists say
  • The Einstein Ring was 3.5 billion light-years away in the Fornax constellation

  • It is the result of light from a distant object passing through a large gravity field

  • This magnifies the distant light, making it easier to observe from the Earth

  • In this case astronomers could study the light from a nine billion year old galaxy

  • The phenomenon was first predicted by Albert Einstein in 1915, which he referred to as gravitational lensing, and formed part of general relativity
