Gravitational wave detectors have "heard" the ripples in space caused by the most massive black hole merger yet. One "forbidden" by current theoretical models.
Tens of thousands of pieces of space debris are hurtling around Earth right now. These defunct satellites, spent rocket stages, collision fragments and even a toolbox threaten active spacecraft and could trigger cascading disasters that make space unusable for generations. Since removing just a single piece of debris can cost tens of millions of dollars, the critical question becomes which ones should we prioritise?
