This game was created for HunJam 2022 in 48 hours. It was inspired by the Event Horizon Telescope Collaboration's picture of the supermassive black hole Sagittarius A*.
27 Μαρ 2024 · A view of the Milky Way supermassive black hole Sagittarius A* in polarised light. The Event Horizon Telescope (EHT) collaboration, who produced the first ever image of our Milky Way black hole released in 2022, has captured a new view of the massive object at the centre of our Galaxy: how it looks in polarised light.
