    Scientists pinpoint location of unexplained space radio signals

    Fast radio burst is coming from a dwarf galaxy over three billion light years from Earth

    A decade ago, scientists first detected fast radio bursts (FRB). They’re so-called because they’re incredibly powerful bursts of radio signals, but they’re extremely short-lived: a few milliseconds in length. Last year, scientists finally managed to catch one happening in real-time. And now we’ve managed to pinpoint where a repeating signal – FRB 121102 – is coming from. What is causing it is still open to speculation.

    “We now know that this particular burst comes from a dwarf galaxy more than three billion light years from Earth,” explained Cornell University’s Shami Chatterjee.

    1. fascinating

    How long did it take to come three billion light years?  I want to know more!!

      3. Three billion years.

      It’s travelling at the speed of light.

      8. A "light year" is actually a unit of measurement, not time.

      A year is a year – so Manny is correct.

      FYI

      A light-year, abbreviation: ly is a unit of length used informally to express astronomical distances. It is approximately 9 trillion kilometres or 6 trillion miles.  https://en.wikipedia.org/wiki/Light-year

      So – it’s a long ways away!

        10. Thank you.

        So maybe the galaxy is no longer there?  This is so curious!  Were the blips a signal?  A blow up?  Zowie, fascinating.

          14. No it isn't there.

          The galaxy is receding from us at a reasonably fast rate of speed. The galaxy we see now was the galaxy as it was and where it was 3 billion years ago. That being the case, the galaxy is now in a completely different place in the universe as it expands. The 3 billion year time lag is referred to as ‘look back time’ since that is exactly what is happening, we’re looking back 3 billion years.

          It gets even weirder. Nothing is where you see it if it is moving relative to you. Not even your hand if you’re waving it in front of your face. There is a very short time lag between the light reflected by your hand to reach your eyes and change into the signal you see.

        19. I knew that three semesters of college physics would be useful someday

        If I ever find a use for Pauli Exclusion Principle, or the Completion Backward Principle for that matter, I’ll be in heaven.

        Talk to ya later!

    2. Intriguing. My grandchildren will probably learn about where these

    signals come from.  Until then . . . .

    4. Wow, that is one big smash-up of galaxies!

    There are at least three galaxies involved in the collision – the two spirals at the nether ends of the spectacle and what appears to be a third in the middle, which appears to be getting pulled apart by the other two.  The wreckage in the middle appears to have been a spiral with a bar still in tact, and the arms that normally spin off the bar have gone all whacky-shaped but still resemble the spiral arms of a disturbed galaxy.  The one-sided, intense brightness and ramrod straightness of the bar in the middle (torn apart) spiral, however, is very unusual looking.  I’ve never seen anything quite like it.  I’m a Galaxy Zoo participant, so I’ve helped to classify thousands of galaxies.  I don’t recognize this one.

    I’m pretty certain that this is NOT a picture of the Fast Radio Burst dwarf galaxy.  It’s just a random image to go with the article, sort of.  Another article on this same subject doesn’t show this photo.

    http://phys.org/news/2017-01-fast-radio-tied-distant-dwarf.html

    Some of the objects in the Universe that have been discovered recently using humanity’s fantastic new technologies and telescopes really defy the imagination.  Some are so unusual that they inspire hopeful speculation about alien civilizations.  However, this radio burst – and magnetars in general – seem so off the charts as to amounts of energy involved, that it is quite difficult to imagine even a very, very, very advanced civilization capable of producing it.  One thinks of “gods” rather than humanoids.  But, as others have pointed out, if we were to be transported back in time to the Middle Ages, with our watches and our hand-held devices with calculators, compasses, levels, aps showing the mapped universe, the Encyclopedia Britannica and more – if not with satellite communications (obviously) – our just with our flashlights and shiny little packets of food-energy – or even just a Bic lighter – in tact, we would be considered “gods” ( or “devils”!).

    SO MUCH has been discovered recently, in astronomy, that is extremely tantalizing, and for sure offers relief from what seems to be “the fall of the Roman Empire Part II” – that is, our civilization coming apart.  For instance, there is water everywhere in the Universe.  It is abundant.  There is water throughout our solar system – on Mars, on the moons of Jupiter and Saturn, on Pluto, on asteroids; I think they even found water on Mercury.  Or: There is at least one earth-like planet around every five stars in our galaxy, and there are one hundred billion to four hundred billion stars in our galaxy.  And there are, of course, billions of other galaxies in the Universe.   A hundred years ago, we didn’t  know there were other galaxies.  We thought the Milky Way was IT.  Boy, were we wrong!  As for the moons of the outer planets spewing volcanoes of water into space, or harboring vast oceans beneath layers of ice, we are talking about a 9.0 earthquake to our poor little psyches, as we realize how vast and rich with the elements of life it all is, and how much we don’t know.

    5. 3 billion light years …….

    And life here on earth started about 3 billion years ago.

      6. Thats not what the fundies would say.

      They would claim about 300,000 or maybe 3000. But not 3 billion. Heavens no.

      Those fundies have to be relevant sometimes with their unscientific babble.

      BTW, those radar dishes appear to be at the New Mexico testing range area near White Sands.

        Wouldn’t it be interesting if these packets of signals contained a message

              16. I had a really good friend that actually did this back then.

              He was really pissed off too.

        15. They're near Magdelina west of Socorro on

        the Plains of Saint Augustine. In the spring and fall you can go visit on special days and have really good personalized tours of the facility and sometimes they partner with New Mexico Tech for a telescope observation party at NMTech that night. Oooops, they have the tours every first Saturday of the month from 11 am to 3 pm.

        You should go check it out sometime.
