The black hole at the heart of galaxy SDSS1335+0728, located 300 million light-years away, was quiet for decades as it consumed little matter and was in a dormant state. But recently it suddenly lit ...

Black holes are fundamental to the structure of galaxies and critical in our understanding of gravity, space, and time. A ...

We all know that black holes can devour stars, rip them apart and consume their remnants. But that only happens if a star ...

Astronomers have reached deeper into the heart of a brilliant cosmic engine than ever before, using NASA’s Hubble Space ...

Supermazes” are theoretical structures that provide a fresh blueprint for understanding the microscopic complexity of black ...

Mergers fuel the most energetic black holes, but not all black holes are fed by gas from a merger. In spiral galaxies, for example, less gas tends to fall into the center, and the central black ...
