They are all originated from the same place. Researchers noticed 10 powerful bursts of radio signals approaching from the same location in space and now they have picked up 6 more of the signals apparently originating from the same location, outside of our Milky Way. These FRB (fast radio bursts) are some of the most indefinable and volatile signals ever noticed from space. They only last for milliseconds, but in that really short-period of time, they produce as much energy as the Sun in 24 hours. But in spite of how powerful they are, researchers are not sure about the cause of these powerful radio signals.
The reason we are so in the unaware about FRB is not that they are uncommon. Scientists have predicted that there are around 2,000 of these FRBs shooting across the Universe every day but that they are so incredibly lived for very shot-period of time that we try hard to detect them. It was only in year 2007 that we discovered fast radio bursts, and it was not until this year that scientists were quick enough to see one happening in real time. Ordinarily we have to research and investigate the events long after the fact occur. But now that we have noticed 6 of the signals and all coming from the similar location, researchers finally start to narrow down possibilities for what could be causing the FRB. The first 10 FRB noticed coming from this one location were first recognized in March last year, but that really happened in May 2015. 6 of the FRB were detected arriving at the ‘Arecibo Radio Telescope’ in Puerto Rico within just 10 minutes of each other.
When the group looked back over the data, they also saw a fast radio bursts from year 2012 that appeared to come from the same location too, making a total of 10 FRB from the one place, and indicating that there was something out there beyond the Milky Way that was continuously creating the extremely intense and short signals.
Now a team of scientists from McGill University in Canada has detected six more of the mysterious signals coming from the similar location, which has become known as FRB 121102, after the first FRB noticed there. "We report on X-ray and radio observations of the only known repeating FRB source, FRB 121102," wrote by the group in The Astrophysical Journal. "We have noticed 6 additional FRB from this spot: 5 with the Green Bank Telescope at 2 GHz, and 1 at 1.4 GHz with the Arecibo Observatory, for a total of 16 bursts from this spot."
