Earth-Shrouding Plasma Tubes

If you haven't seen this by now, you'll want to check it out! It seems that the world of astrophysics has been set all agog by a brilliant Australian undergraduate student's recent discovery. Cleo Loi from the University of Sydney has used a combination of radio telescopes to prove the existence of earth-surrounding tubular plasma ducts. Travelling from the ionosphere to the edges of space, these multi-layered plasma tubes were believed to exist but were never proven ... until Ms. Loi and her team managed to image them:


What the implications might be when it comes to their influence on radio propagation, if any, remains to be seen but I suspect that astrophysicists all over the world are having a close examination of long-held theories and the implications on their own fields of study.

    trying to see the furthest reaches of the universe and until now did not understand the mechanics of objects close to home.
    Brilliant work. I hope this leads to more research which my help us to understand the impact of these tubes on the Earth as well as the ionosphere itself.

  • Richard KWøU:

    Really interesting. This might explain the Long Delayed Echoes that you occasionally hear on radio.

  • Sverre LA3ZA:

    I was thinking the very same thought as KW0U myself – maybe it could help to resolve e.g. the 3. mechanism for Long Delayed Echoes that I discussed here in “The Five Most Likely Explanations for Long Delayed Echoes” http://heim.ifi.uio.no/~sverre/LDE/, that is the mechanism for mode conversion involving coupling to mechanical waves in the ionosphere.

  • David WB4ONA:

    A .PDF of this paper seems to cost $38 USD to access and is controlled by Wiley. It also appears this research is Australian Taxpayer funded. So if you are an Aussie, you should be mighty angry about this.

    Fascinating!
