What can astronomers learn from observing black holes that suddenly wake up? This is what a recent study published in Nature Astronomy hopes to address as an international team of researchers ...

Physicists have not yet watched a black hole literally blow itself apart, but they are closing in on the conditions where such an event might finally be seen. At the same time, telescopes are catching ...

Some things in cosmology may simply be unknowable. Why is there something rather than nothing? What lies outside the universe? What is inside a black hole? That last one has been niggling at ...

A new book demystifies black holes and explores what we still don’t know about them James Trefil and Shobita Satyapal The first direct visual evidence of the supermassive black hole in the centre of ...
