Recorded a mysterious radio signal outside our galaxy




Astronomers were in heaven fishing, catching pulses of neutron stars, and other radio bursts when they found something unexpected, whizzed into the sky and fall into the trap Parkes radio telescope in New South Wales, Australia. Let us not forget that the aliens, and the manifestations of their vital activity is a constant hunt .

Powerful signal that lasted only a millisecond, and could be a coincidence, but this was followed by three exactly the same energy flare emanating from different points in the sky. Subsequent analysis showed that in contrast to the majority of cosmic radio signals generated in the Milky Way or nearby galaxies , the four appeared beyond.

Whatever caused the signals, they came and went. The signals recorded in the period between February 2011 and January 2012, were single events, so many of them do not squeeze out.

What is known is that in just a few milliseconds each of the signals produced as much energy as the Sun radiates in 300 000 years.

“They have gone a long way so that by the time they reach the Earth, the Parkes telescope should have had a million years to collect the energy equivalent of a flying mosquito energy”, – said the astronomer Dan Thornton of the University of Manchester in a letter to Discovery News.

Scientists have produced a number of theories that could explain the birth of this exotic phenomenon. Among the contenders – the clash of magnetars, which are neutron stars with superstrong magnetic field, the evaporation of black holes, and gamma-ray burst from the birth of a supernova.

Or, according to Cornell University astronomer James Cordes, bursts could be born as a result of a completely new type of high-energy astrophysical events.

“It is too early to determine the origin of such a sufficiently obvious, but very rarely latched events” – Cordes wrote in an article published in the journal Science.

Whatever happens, it seems to be fairly common, but difficult to find the phenomena. According to astronomers, the sky is about 10,000 similar high-millisecond radio bursts every day.

“We need a very big telescope to detect them”, – adds Thornton.

As a general rule, telescopes observing at the same time only a very small piece of the sky, so “you have to look very long to see a lot of these events. That’s why we have a handful of them yet. ”

Previously detected similar signals, but astronomers could determine they made out of the galaxy or beyond.

Thornton and his team have made it through the characterization of the plasma through which passes the RF signal before it reaches the telescope. The waveform varies depending on the amount of plasma through which the signal passes.

The astronomers found that these four signals are passed through the plasma is much more than that which is in the interstellar gas of the Milky Way.

Scientists suspect that between galaxies have extra gas. This discovery opens the door to a potentially new technique of studying the content of distant galaxies and what lies between them.
