Black holes are places where gravity is so powerful that nothing — not even light — can escape. Rather than being empty, black holes are chock full of matter that gets squeezed into a teensy space.

How did supermassive black holes get big so fast? Astrophysicist Souphie Koudmani tells us how she and her colleagues are finding out. A fresh analysis of decades-old X-ray black hole jet data has ...

The newly discovered "blazar," which has a mass equal to 700 million suns, is the oldest of its kind ever seen and changes what we know about the early universe. What knocked this black hole over onto ...
