Title: Cheap Astronomy – Dear CA #65: Unusual Orbits
Organization: Cheap Astronomy
Description: Cheap Astronomy stumbles around in the dark.
– How do stars in the galaxy orbit?
There is something weird about how stars orbit in the Milky Way Galaxy – and probably in any other rotating galaxy. But the physics of it is totally different to how things work in, say, our Solar System.
– Why doesn’t the image of the black hole in M87 look like the image of the black hole in the movie Interstellar?
So the back story here is that astronomers recently imaged the supermassive black hole within the elliptical galaxy M87 although when we say imaged it’s really radio telescope data converted into a visual light approximation, but it’s still an image – just perhaps not exactly what you’d see if you parked your spacecraft out at a safe distance and took a peek.
