Alien cosmic radio bursts of light, aka The Signal, aka Fast Radio Bursts were witnessed in real time on May 15, 2014 by astronomers in Australia.
Dr. Emily Petroff, a Veni Fellow at the University of Amsterdam Anton Pannekoek Institute , caught the mysterious signal as it happened using the Parkes Telescope in New South Wales.
The source of these alien signals is unknown and astronomers have no definitive answers as to what it is. Only eight of these fast radio burst (FRBs) have been recorded in the past and they were all discovered weeks, and sometimes years, after the actual event took place by studying old data—never at the time of the actual occurrence like this latest event.
The first fast radio burst was discovered in 2007,” Petroff told Fox News.
Data gathered by the Parkes Telescope sheds new information on the property of the bursts. The waves appear to be circularly polarized as opposed to linearly polarized, meaning they vibrate in two planes, not one. “It’s something nobody has ever measured before,” Petroff said.
According to Keith Bannister of Australia’s Commonwealth Scientific and Industrial Research Organization, “Nobody knows what to make of it. But, we alien hunters are told not to get our hopes up.
Petroff tells us, “We’re confident that they’re coming from natural sources, that is to say it’s probably not aliens, but we haven’t solved the case completely. The two most promising theories at the moment are that these bursts could be produced either by a star producing a highly energetic flare, or from a neutron star collapsing to make a black hole. Both of these things would be from sources in far-away galaxies just reaching us from billions of light years away.”
The following information is from the website of Emily Petroff on her research:
In recent radio surveys at Parkes astronomers looking for new pulsars also found a new type of pulsed object since called Fast Radio Bursts (FRBs). Fast radio bursts appear as single, bright, very short radio pulses that have never been seen to repeat. The pulses only last for a few milliseconds, similar to the duration of a pulsar pulse, but have properties that lead us to believe that they originate far outside the Milky Way, where normal pulsars cannot be detected.
So what could be the source of FRBs? Many different theories exist as to what causes FRB pulses but none has yet been confirmed. Some believe they are explosions in distant galaxies, or flares caused by distant magnetars, highly magnetic pulsars that emit bursts of powerful radiation. Others believe they originate in our own Galaxy, but from bursty flare stars. I work on several observing campaigns currently trying to answer these questions!
Based on the number of FRBs that have been found in radio surveys so far, we believe that up to 10,000 FRB bursts happen every day! Meaning that if our eyes could see at radio wavelengths, we could look up into the sky and see an FRB twinkle every 10 seconds!
FRBs are a new and exciting mystery object that I work to understand. Collecting data and testing theories is the best way to understand their origins and some of my most recent work focuses on these incredible new sources.
Cool video explaining FRBs.
A Big Picture
This sweeping bird’s-eye view of a portion of the Andromeda galaxy (M31) is the sharpest large composite image ever taken of our galactic next-door neighbor. Though the galaxy is over 2 million light-years away, The Hubble Space Telescope is powerful enough to resolve individual stars in a 61,000-light-year-long stretch of the galaxy’s pancake-shaped disk. It’s like photographing a beach and resolving individual grains of sand. And there are lots of stars in this sweeping view—over 100 million, with some of them in thousands of star clusters seen embedded in the disk.
This ambitious photographic cartography of the Andromeda galaxy represents a new benchmark for precision studies of large spiral galaxies that dominate the universe’s population of over 100 billion galaxies. Never before have astronomers been able to see individual stars inside an external spiral galaxy over such a large contiguous area. Most of the stars in the universe live inside such majestic star cities, and this is the first data that reveal populations of stars in context to their home galaxy. —Ray Villard Space Telescope Science Institute, Baltimore, Md.
Below is a video, set to music, of this bird’s-eye view of the Andromeda Galaxy. Be sure to watch until the end. You won’t be sorry. You might go: Oh, Wow! Like I did.
My Response to NASA’s Big Image
Mighty Big Picture for us Earthlings to assume all that vast unknown is just for us. Any thoughts? I love hearing from you.
