Here is an article from Space.com about observations taken by the Event Horizon Telescope. It also has a quiz about BH's but I'm not sure if it will come through with the article. Test your knowledge of black holes.

The question "black holes have infinite..." where the correct answer is "density" is a bit misleading. The singularity has infinite density, but a black hole's volume is typically defined with a radius at the event horizon inside which the density need not be unreasonably large.

Yes I agree Modest, If I remember correctly I think I got that one wrong.
