P or the first time, astronomers were able to identify the source of a “quick start radio” cosmic phenomenon still mysterious . This very brief flash of radio waves spotted by telescopes came from a galaxy 6 billion light years from Earth, according to a study released Wednesday.
“quick bursts radio” their nickname FRB (Fast radio burst) were highlighted in 2007 by a team of scientists led by Duncan Lorimer, from data collected by an observatory.

in a millisecond, they emit as much energy as the Sun in 10 000 years.
It is very difficult to detect directly. This is what the Parkes radio telescope in Australia April 18, 2015, bringing to 17 the number of FRB identified to date.

The cause of the radio flashes is unknown and hypotheses abound.
“There are currently more ideas on the nature of the source of the FRB has identified that there FRB”

They may result from the neutron stars merge (tiny but very dense stars), says Evan Keane, senior author of the study published in the British journal Nature.
Aliens signals?
Other scientific even imagine extraterrestrial signals. What about him? “No, sorry,” answered Evan Keane, one of the architects of the International SKA radio telescopes network project.
When the Parkes radio telescope, which measures 64 meters in diameter, detect the FRB 150418, an international alert was given for other telescopes mobilize immediately.
Soon after, afterglow FRB are marked. They were followed for six days.
A telescope on Hawaii Island then establishes that the FRB comes from an elliptical galaxy at 6 billion light-years . A light year corresponds to 9461 billion kilometers.
