View Full Version : Magnetic Fields Confine a Dying Star's Jets

SUMMARY: Radio astronomers have uncovered a dying star with twin jets of material confined by a powerful magnetic field. The star is located about 8,500 light-years away from Earth in the constellation of Aquila, and it's in the process of forming a planetary nebula. Many stars like this produce elongated nebulae, where the star's outer envelope is pushed away and channeled into tight jets. The jets come out in a corkscrew shape, which means that the star is slowly rotating.

The resolution of the VLBA is amazing...

Splendid!

Now all we have to find out is where these magnetic fields come from and why are they arranged in this way.

Cheers.

In case you missed it, VanderL is making sort of an understatement joke, because the business of figuring this out is no simple trick.

Anyone friendly to the idea that the magnetic fields are direct evidence of current flowing?

I have recently 'converted' from the gravity only, theoretical view to an electrical interpretation. Quite interesting after many years in college and a lifetime growing up with the standard view.

Hi Halo, welcome to the BAUT forum.
We have a lot of discussion of the Electric Universe, but it is confined to a thread in the Against The Maintream section of this forum. This is your first post here, so no warning is issued. Please particiapte in the EU thread with your EU comments, and contribute any mainstream astronomy observations wherever it seems to fit.

you could of course take a middle position......considering that we appear to have 2 forces effecting astronomic events.

ie:

gravity and electromagnetics.

You could. I think it would be fair to say there are four forces. However, to say that EM confines the jets is within mainstream astronomy.

right....halo's interest in an "electrical" reasoning for some phenomena doesn't necessitate shunting him/her into the EU thread....just like having concerns over the accepted gravitic theories doesn't necessitate shunting people into the eg: mond theory.

a while back Nereid requested that if you are not a proponent of EU..then you should keep your nose out of that thread....so you should confirm that halo is such a proponent before sending him/her to that thread.

as antoniseb (and this article) have pointed out:
the standard view has changed over time...and includes explanations for both gravitic and electromagnetic space phenomena.
