"What's your favourite black hole?"
We put your Twitter questions about black holes to space expert and astrophysicist Elizabeth Pearson from Sky At Night Magazine.
Unless you've been hiding behind Planet X for the last few days, you've probably heard a thing or two about black holes, specifically Messier 87. The reason a celestial object some 55 million light years away is hitting the headlines is because astronomers using the huge, planet-sized Event Horizon Telescope have captured an image of a black hole. It's the first time we've seen an actual "photo" of a black hole, and M87 makes a very fetching model indeed.
All this excitement got us thinking about black holes, and how much we don't actually know about them. We've answered a fair few questions about them in our time, but we're well aware of the gaps in our knowledge, which is why we asked Elizabeth Pearson, the resident space expert at Sky At Night Magazine, to enlighten us and our followers on Twitter.
Here's a selection of some of the best questions below, but if you do have any more black hole questions, or questions about anything, email us at firstname.lastname@example.org (don't forget to include your name and location) or tweet @sciencefocusQA.
