First radio observations of the lonely, planet-like object OTS44 reveal a dusty protoplanetary disk that is very similar to disks around young stars. This is unexpected, given that models of star and planet formation predict that formation from a collapsing cloud, forming a central object with surrounding disk, should not […]

Quasars are luminous objects with supermassive black holes at their centres, visible over vast cosmic distances. Infalling matter increases the black hole mass and is also responsible for a quasar’s brightness. Now, using the W.M. Keck observatory in Hawaii, astronomers led by Christina Eilers have discovered extremely young quasars with […]
