Show HN: Physically accurate black hole simulation using your iPhone camera (apple.com)
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.

The Event Horizon Telescope image might need a correction (academic.oup.com)
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? (quantamagazine.org)
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 (phys.org)
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.
