An enigmatic radio signal is an aid to astronomers in solving the puzzle that is the universe.

Astronomers have detected a radio burst which has its origin in deep space. This one is the strongest one to reach earth so far. It is in fact the 18th fast radio burst (FRB).

Scientists however do not know exactly what these bursts of energy happen to be in the first place. The source has been given a focal point by the astronomers though.

Scientists have been able to figure out the depth and movement of the intergalactic particles that lie between the earth and this source of FRBs. 

The materials from which galaxies are formed and what the universe is made of can be better known via this method. Recording FRBs is a very clean cut way of exploring space.

The flashes are only for a few milliseconds. They seem to arrive from a source away from the Milky Way Galaxy. A dozen of these bursts have been detected so far.

Yet astronomers are sure that thousands of these bursts take place in the sky every day. The fact remains that there is no consensus about what causes these bursts in the first place. 

Some say that collisions between neutron stars cause them to occur. It is entirely possible that multiple causes lie behind these bursts. What we do know is that these radio waves occur at gigahertz frequencies.

These are on the same wavelength as cell phones. Also telescopes exist that can pick up these signals in a jiffy. One such telescope is the CSIRO Parkes observatory in Australia.

The FRB found via this telescope was high energy and the research team could detect its source in the sky. It was a billion light years away, according to The Verge

Many possible galaxies could have been the source points for this signal. The topmost choice is VHS7. It is still a moot point though. A large part of the universe is in the form of plasma matter.

This was known through this FRB which illuminated the matter that lay in between stellar and intergalactic stuff. This is the first time that such indirect measurements were taken of the universe. The evolution of the universe and its large-scale structure can be gauged through this methodology.
