Researchers from the International Centre for Radio Astronomy Research (ICRAR) in Western Australia used seven of the world’s most powerful telescopes to observe galaxies at 21 different wavelengths of light, from the far ultraviolet to the far infrared - the most comprehensive audit of the energy output of a nearby part of the Universe.

Highlights

  • Initial observations were conducted using the Anglo-Australian Telescope in New South Wales.
  • Two orbiting space telescopes operated by NASA and another belonging to the European Space Agency.
  • The research is part of the Galaxy and Mass Assembly (Gama) project, the largest multi-wavelength survey of space.
  • Study of over more than 200,000 galaxies has revealed that energy levels are falling and not even half of what it was two billion years ago, signaling an ageing Earth.
  • Scientists believe that the Universe has started its slow process of ageing and may die in the next 10 billion years.
  • Several research studies have explored the concept of the ‘ageing Universe’.
  • It is believed that when the Universe was created, it took place about 13.8bn years ago. The stars and galaxies are still expanding at an accelerating rate, suggesting there is a mysterious “dark energy” overcoming the unifying effects of gravity.
