Quasars

Quasar J0742+2704 (center) became a topic of interest for astronomers in 2020 after it was discovered to have a new jet emanating from the disk around its supermassive black hole. The discovery was made using the Karl G. Jansky Very Large Array (VLA) radio observatory. Follow-up observations were subsequently made with other observatories, with the aim of determining the properties of the galaxy and understanding what might have powered the jet. **Credit:** NASA, ESA, Kristina Nyland (US Naval Research Laboratory); Image processing: Joseph DePascala (STScI).
