Approximately six years ago, a single burst of radio emission of unknown origin was detected outside our Galaxy but no one was certain what it was or even if it was real.
Now there is no doubt that they are real!
An international research team has indeed detected mysterious bursts of radio waves coming from billions of light years away by using the CSIRO Parkes 64metre radio telescope in Australia.
Based on physical properties such as brightness, distance and energy, the scientists could determine that:
- Their origin is celestial rather than terrestrial.
- They come from cosmological distances when the Universe was just half its current age
- They originate from an extreme astrophysical event involving relativistic objects such as neutron stars or black holes.
- One of these signals going off every 10 seconds.
Their findings are published in Science Magazine.
