Researchers using MeerKAT have found nine millisecond pulsars, the majority of them in uncommon and occasionally unusual binary systems.
A condensed collapsed star has chewed up and eaten almost the total mass of its stellar companion. In so doing, it has become the heaviest neutron star observed to date.
Quasars can eject material at high speeds, possibly helping to drive the blowout and regulate star formation in their host galaxies. However, many aspects of this evolutionary scheme are not understood.
Astronomers are now closer to understanding how gravity works across the universe, thanks to a 21-year study of a pair of stars, a pulsar and a white dwarf.
The Hubble Space Telescope has documented a set of enigmatic quasar ghosts. These ethereal green images mark the graves of these objects that flickered to life and then faded.
