Researchers detected six radio energy bursts which may be three billion light years away from the earth. The detection also followed 11 old blasts from same place. The exact place of the radio energy is unknown, but according to researchers it could be a neutron star.
The first signals were received in Puerto Rico at the Arecibo radio telescope within just 10 minutes of each other. The researchers from McGill University in Canada also reported the signals from the same location, in the Auriga constellation, which is about 2 billion lightyears away from Earth. There were already 18 FRBs detected and recorded since 2007. The scientists are searching for the probable source of the repeating signals.
The findings of the discovery were printed in The Astrophysical Journal on Dec. 20, 2016. The scientists said that they report on radio and X-ray observations of the only known repeating fast radio burst source, FRB 121102. They further said that they have detected six additional radio bursts from this source: five with the Green Bank Telescope at 2 GHz and one at 1.4 GHz with the Arecibo Observatory, for a total of 17 bursts from this source.
Science Alert reports that these fast radio bursts (FRBs) are some of the hardest to pin down and the most explosive signals ever detected from space. They only last milliseconds and generate much energy as the Sun in the whole day. Scientists are puzzled of what causes them.
The team also cannot figure out the exact location of FRB 121102. On the other hand, based on the way their lower frequencies are slowed, the team thought that they might come from far beyond the Milky Way. This could give hints of what trigger the events.
Meanwhile, the team said that whether FRB 121102 is a unique object in the currently known sample of FRBs, or all FRBs are capable of repeating, its characterization is extremely important to understanding fast extragalactic radio transients. Scientists have been keen on detecting more of these FRBs and are trying to identify where they come from that would later give insights into the mysteries of the universe.
