Breakthrough Listen, an initiative to find signs of intelligent life in the universe, has detected 15 brief but powerful radio pulses emanating from a mysterious and repeating source – FRB 121102 – far across the universe.

Fast radio bursts are brief, bright pulses of radio emission from distant but largely unknown sources, and FRB 121102 is the only one known to repeat: more than 150 high-energy bursts have been observed coming from the object, which was identified last year as a dwarf galaxy about 3 billion light years from Earth.

Fast Radio Bursts Could be Caused by Pulsars Near Black Holes or Supernova Remnants 3 comments

Fast radio bursts (FRBs) may be caused by neutron stars (pulsars) experiencing unusual conditions, such as proximity to a black hole or a highly magnetized wind nebula:

The first FRB was discovered in 2007, in archived data from the Parkes Radio Telescope in Australia. Astronomers were searching for new examples of magnetised neutron stars called pulsars, but found a new phenomenon - a radio burst from 2001. Since then, 18 FRBs - also referred to as "flashes" or "sizzles" - have been found in total.

The mystery surrounding their nature has spawned a variety of different possible explanations, from black holes to extra-terrestrial intelligence.

Only one of these sources of radio energy has erupted more than once - a so-called burster catalogued as FRB 121102. This FRB has sent out around 150 flashes since its discovery in 2012.

Now, in the journal Nature [DOI: 10.1038/nature25149] [DX], a team of scientists explains how the emission might come from a neutron star, perhaps one near a black hole or one embedded in a nebula.

            I like how this is modded 'Interesting'. 'Fascinating, Captain', maybe. But Interesting? :)

            I'd go for "Kill all the men and take all the good looking nerdy girls between 18 and 25."

              Well, when this came out it prompted me to look up a great Star Trek: TNG episode "Who Watches the Watchers" [wikia.com] in which a Federation outpost studying a Bronze-age society of proto-Vulcans has its holographic cover blown and the crew of the enterprise has to go into full damage-control mode.

              It's a cool episode because the problem is not solved by force or technology. In fact, Captain Picard dares a motherfucker to shoot him with an arrow and gets hit to prove he's not God.

              That's one thing the prime directive never addressed - a situation in which civilizations were trying to reach out and respond to long-range radio bursts rather than just flying over and beaming down to the place.

              Now that would be great if the moderation options were replaced with:

              No. But it is... interesting!

            Except, little know fact, Ethanol_fueled is a woman. This is what happens when extra-stellar species arrive, and cannot figure out the local reproductive strategies. Sad thing, Eth will not realize this until well after his fleshlight gives out. So sad. But at least it stops with him. Or, um, her.

    I welcome our new high energy radio overlords.

    As long as it's rock/alternative radio overlords. No Michael Jackson or what today passes as pop music.

      If they beamed out details about their technology, it could improve our own, even if they stopped existing millions of years ago.
