Some More Mysterious Extragalactic Signals Detected

Some More Mysterious Extragalactic Signals Detected

Remember the ‘Independence Day’ starting? Same happened twice recently, according to an online report published at Cornell University Library website. Two mysterious radio wave bursts were captured which came from out space. Four more flashes were detected as well.

The report said that in 2007, the first burst was detected. It stayed for a few milliseconds and was quite a bright radio energy burst. So far, in total nine reports of this type of incident has been recorded. All these are believed to be came from outside of milky way. But scientist found no more information in later searches, even using non-radio telescopes.

In Australia, Parkes radio telescope caught five signals. One of them, had an exception. It blasted twice, in between 2.4 milliseconds. According to scientists in Germany’s  Max Planck Institute for Radio Astronomy, It had the same pattern that happened 9 billion years ago in the constellation Octans.

Till now, there was the concept that two neutron stars, dense cores left behind by dead massive stars, can collide only once. Rare vigorous blasts from pulsars might fit the bill, as would hyperflares from haphazard sources of gamma rays and X-rays known as “soft gamma repeaters,” possibly triggered by starquakes on highly magnetic neutron stars. But after these unusual incidents, they are being revived.
