Six more radio signals from deep space deepen mystery …
A total of 17 such radio signals — called fast radio bursts (FRBs) — have been received from this location in space since their discovery in 2007.
Scientists have discovered six more bursts of radio signals coming from a place in deep space outside our galaxy from where similar signals were detected earlier this year and in 2012.
A total of 17 such radio signals have been received from this location in space, and given their nature, speculation has already begun on whether we are being hailed by extra-terrestrial life forms.
The signals — detected at the Green Bank Telescope in the US and the Arecibo Observatory in Puerto Rico, according to an article in the Astrophysical Journal — are described as Fast Radio Bursts (FRBs). Discovered only in 2007, FRBs are really fast radio signals that last for only a few milliseconds, and can be detected only with special equipment.
What’s also special about these FRBs is that even though they exist for such small duration, they tend to generate so much energy that it could parallel the amount of energy generated by the Sun for a whole day!

It is this aspect of the signals — as well as the fact that now a total of 17 such signals have been detected so far from the same region in deep space well beyond our galaxy — that is leading to speculation that there may be a sufficiently advanced extraterrestrial civilization behind them.
KARDASHEV SCALE
The technological expertise of civilizations is often determined by the Kardashev scale, named after the Russian scientist who proposed it in 1964. It proposes that there are three kinds of civilizations across the universe: Type I, which utilizes only that much energy which reaches it from its nearest star; Type II, which has harnessed entire energy of its nearest star for use across various planets; and Type III, which has harnessed the energy of stars across its entire galaxy.
Given the nature of the newly-received FRBs — specifically their energy — it is being speculated that if their source is artificial, they could have been sent by at least a Type-II extraterrestrial civilization as a means to reach out to other, similarly intelligent civilizations. That is because the amount of energy in these FRBs cannot be produced by any conventional means known to man, but could be emitted by an artificial source from a civilization that has harnessed the power of an entire star.
