After capturing first black hole photo, Event Horizon Telescope focuses on cosmic jets

After capturing first black hole photo, Event Horizon Telescope focuses on cosmic jets CNET 3 hrs ago © Nature Astronomy Until now, the highest resolution image of Centaurus A s jet comes from the Tanami array (first panel). The EHT was able to zoom in 16x better than Tanami to produce the image in the middle panel of its plasma jet. The third panel is the plasma jet observed in the Messier 87 galaxy. Are all black holes functioning the same, regardless of size? We tend to think of black holes as gargantuan, light-eating behemoths. But even supermassive black holes, the gravitational sinkholes that exist at the center of galaxies, come in an array of sizes. Take M87 , which lies at the center of the Messier 87 galaxy. It s about 6 billion times more massive than our sun. Or you could look at Sgr A , which lies at the center of the Milky Way and is only (

Thousands of galaxies classified in a blink of an eye

Astronomers have designed and trained a computer program which can classify tens of thousands of galaxies in just a few seconds, a task that usually takes months to accomplish. In research published today, astrophysicists from Australia have used machine learning to speed up a process that is often done manually by astronomers and citizen scientists around the world.
