Ten years ago, astronomers made an epic discovery with the Laser Interferometer Gravitational-Wave Observatory. Cosmology hasn’t been the same since, and it might not stay that way much longer.
Ripples in spacetime? Neil deGrasse Tyson and comedian Harrison Greenbaum explore black hole collisions, quantum tricks, and how gravitational waves can help us uncover the early universe with MIT physicist and LIGO researcher Nergis Mavalvala.
Dark Enegy and Black Holes, What's the story here?
What if dark matter is just ordinary matter locked inside black holes – from which, after all, light cannot escape. Such massive, dark objects would trundle around the cosmos, nudging the motion of visible matter while evading direct detection.
If nothing gets out of a black hole, how does gravity do it? Something with virtual gravitons? Is this really necessary? It's tricky question, but this is what I can say without resorting to equations.
Black holes are weird already, but it turns out that the black hole at the centre of the Milky Way Galaxy is a particularly weird one
Black holes were thought to arise from the collapse of dead stars. But a Webb telescope image showing the early universe hints at an alternative pathway.

On May 12, 2022, astronomers on the Event Horizon Telescope team released an image of a black hole called Sagittarius A* that lies at the center of the Milky Way galaxy. Chris Impey, an astronomer at the University of Arizona, explains how the team got this image and why it is such a big deal.
The biggest reveal in human history: an image of the supermassive black hole, Sagittarius A*, at the center of our Milky Way galaxy.
