The 1st image of a black hole’s magnetic field
Using the data from the first image of a black hole, obtained in 2019, scientists have now extracted evidence of the magnetic field lines near the event horizon, and from this produced the first image of such lines.
The image to the left, reduced to post here, shows the spiraling magnetic field lines against the bright event horizon ring.
As the Event Horizon Telescope (EHT) team describes today in a pair of papers in Astrophysical Journal, the new picture uses the same data as in the original image, produced from a series of observations in 2017 of the supermassive black hole at the core of nearby galaxy M87, using the combined collecting power of eight radio observatories across the world. To extract the polarization information, the data have gone through many months of additional analysis.
The scientists also note that the orientation of the field lines might eventually help explain the jets being thrown from its poles.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon or from any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.

Aren’t magnetic field lines “loops”? These seem to arc out into nowhere.
We’re looking at a 3D (4D?) object from a 2D perspective. That field lines are discernable is amazing.
Interesting. The theory’s concerning Black holes very widely. From a super dense ball, to a flat disk.
The difference depends on how fast it is spinning?
The interesting thing is, although “matter” such as light cannot escape a black hole, natural “forces” such as gravity and magnetism is unaffected. Noticing that the rotation of the black hole bends the toroidal magnetic field around it’s self in a curve, I wonder if the effects of the time distortion are visible in this manner from an object so far away. (Although it is spinning very fast, it is not spinning at all from our frame of reference because inside the gravitational field, time has stopped, allowing us to get a good picture of the magnetic field loops which would normally be blurred)
The implications are considerable as it shows a kind of fiction between what we are told, and what our lying eyes tell us differently.
