Six years after the historic release of the first-ever image of a black hole, the Event Horizon Telescope (EHT) Collaboration unveils a new analysis of the supermassive black hole at the heart of the galaxy M87, known as M87*. This analysis combines observations made in 2017 and 2018, and reveals new insights into the structure and dynamics of plasma near the event horizon.

Researchers spot black hole feeding at 40x its theoretical limit
(arstechnica.com)
How did supermassive black holes end up at the center of every galaxy? A while back, it wasn't that hard to explain: That's where the highest concentration of matter is, and the black holes had billions of years to feed on it. But as we've looked ever deeper into the Universe's history, we keep finding supermassive black holes, which shortens the timeline for their formation.

What would the world around you look like if you were staring at a black hole? This application places a black hole in the field of view of your iPhone’s camera and gravitationally "lenses" the resulting live video feeds just as a black hole would warp the light from surrounding stars.

We propose that the ring structure found by the Event Horizon Telescope Collaboration (EHTC) as the black hole shadow of Sgr A* is an artefact caused by the bumpy point spread function (PSF) of the EHT 2017 data.

How do merging supermassive black holes pass the final parsec?

Galaxies have been merging into ever-bigger structures over the course of cosmic history. When galaxies merge, the supermassive black holes that sit in their centers must eventually merge, too, forming an even more gargantuan black hole.

A wobble from Mars could be sign of dark matter

In a new study, MIT physicists propose that if most of the dark matter in the universe is made up of microscopic primordial black holes—an idea first proposed in the 1970s—then these gravitational dwarfs should zoom through our solar system at least once per decade.
