The new black hole photo polarized. On the left the real photo, on the right simulations of the powerful jets shooting out from its core

Back in March I posted about my trips to ALMA and in particular the first ever black hole photo that was produced by the Event Horizon Telescope. Now they´ve made an upgrade and have photographed the same photo with polarization showing the effects of the magnetic fields. Take a look at this.

One of the things I learnt from my trips to ALMA was that the first photo ever taken of a black hole was not a finished mission but actually would be an ongoing project for many years to come. Which is why I wasn't too surprised when ALMA came out with an upgraded version of the photo recently showing how it looks in polarized light.

Before and after. With and without polarization

Now, I can't even begin to do justice to how amazing this new photo is and what it means in terms of our discoveries, but I encourage you all to have a look on ALMAs website all about how they did it.

To summarize though the new improved photo shows light in polarization that is a result of the magnetic fields shooting out powerful jets from the core of the black hole. Yet another discovery in ALMAs long list of groundbreaking work.
