researchers pick up sound from 5.5 billion light years from Earth

Contact ! A team of researchers from the University of Swinburne has just indicated that they have captured in real time what is called a rapid radio wave burst (FRB) of only a few milliseconds.

space The event took place on May 14, but the results have just been published. The source of the phenomenon is located some 5.5 billion light years from our Earth, outside of our galaxy. Radio waves travel at the speed of light, about 300,000,000 meters per second.

This is not the first time that we have witnessed this phenomenon, which was observed several times between 2007 and 2013. Last July, it was Arecibo's radio telescope located in the middle of the jungle that detected mysterious radio pulses ultrafast whose provenance is external to Earth.

By comparing the various observations, it is now clear that these are not "simple measurement errors", especially since this time, the Parkes observatory observed the phenomenon in real time.

Researchers say startle "could have potentially released as much energy in a few milliseconds as what the sun produces in 24 hours." Its origin remains uncertain. Some thus evoke the evaporation of a black hole, others the collision between neutron stars … Impossible to know for the moment what this burst corresponds to.

In the coming months, scientists will be listening to this type of signal to try to refine its location, in order to estimate the date.
