A team of astronomers at the Event Horizon Telescope (EHT) collaboration has just released an incredible new glimpse of the “heart” of a nearby galaxy. The organization previously unveiled the first-ever image of a black hole.
The heart, a supermassive black hole 55 million times the Sun’s mass, while not beating, is spewing a jet of high-speed particles. And it’s not clear exactly why.

SciTechDaily reported on the image of the supermassive black hole at the center of our nearest radio galaxy, Centaurus A. A radio galaxy is one that we Earthlings identify by its emissions in the radio frequency of the electromagnetic spectrum. Meaning the galaxy is so distant, the lightwaves that reach us are low frequency enough not to fall into the visual spectrum.

Now, I have joined the Event Horizon Telescope team in following up on their earlier achievement, by creating a new image showing jets of plasma being ejected from the core of a different supermassive black hole, at the centre of the galaxy Centaurus A.
Centaurus A’s black hole is about 120 times less massive than that of M87, the galaxy where the black hole halo was spotted (and which also has its own set of plasma jets). So no black hole shadow was expected or seen in Centaurus A’s case.
