Research investigates radio galaxy 3C 84
An international team of astronomers has conducted a detailed kinematic study of a radio galaxy known as 3C 84. The research sheds more light on the properties of this source and its connection to gamma-ray emission. The ...
Could we harness energy from black holes?
A remarkable prediction of Einstein's theory of general relativity—the theory that connects space, time, and gravity—is that rotating black holes have enormous amounts of energy available to be tapped.
