Caught in the act: galaxies turning into quasars
Rumors of a quasar’s death may have been premature
Astronomers find 83 quasars already shining in early universe
Seek out 3C 273, the brightest optical quasar, in the spring sky
Plumb the hidden depths of spring’s deep-sky by seeking out 3C 273, the optically-brightest quasi-stellar object (QSO) in the constellation of Virgo. Quasars are the intensely luminous centres of very distant and active galaxies, powered by a supermassive black hole. And don’t worry that you need a huge ‘scope to see it – a 15-cm (6-inch) instrument and a clear, moonless night are all you need.
