Unexplained radio waves from space have for several years puzzled scientists. Now they are closer to an explanation.
In the past eight years, scientists have been mystified by a short, sudden and inexplicable burst of radio waves from space.
According to Nature News, the most detailed study has finally provided a hint about where the radio waves may originate from.
The rapid burst of radio waves, according to the study, comes from a magnetized region of space and are probably sent from a young neutron star - a compact star, which consists primarily of neutrons.
The rapid burst of radio waves lasts no more than a few thousandths of a second, and when they were first discovered in 2007, several experts, according to Nature News, considered that it was merely errors in the measurements.
But in the past three years, 15 other radio waves have been discovered, and it has led researchers to believe that the radio waves have their origin in the cosmos.
In a number of media there are more or less spectacular theories put forward - such as the radio waves could come from life forms in other galaxies.
However, in the new and thorough study, the researchers reviewed data from the Green Bank telescope Hydrogen, which is in West Virginia, USA.
The researchers' analysis suggests that a radio wave outbreak in May 2011, has its origins extremely far away from Earth - about six billion light years away.
Scientists believe the radio waves have been created by a star-quake - that is shaking of the star, reminiscent of earthquakes on Earth.
An alternative explanation, according to researchers, could be that a young but very large neutron star may have sent out a radio wave when it suddenly collapsed to form a black hole, writes Nature News.
Although the new study brings us one step closer to an explanation of the mysterious radio wave signals, the mystery remained unresolved.
The study was published in the scientific journal Nature.
