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).

Hubble's Spiral Surprise: Quasar Discovery That Disproves Theories

The Hubble Space Telescope has revealed a quasar inhabiting a spiral galaxy – a surprising discovery that challenges existing understanding of the structure of quasars and the origin of their jets of matter.

The divergent adaptation of cuckoos

Cuckoos develop eggs and chicks that resemble those of their hosts, to avoid detection. When they have more than one host, this can lead to the creation of new species of cuckoos – especially if they are “violent”.
