    Lightest Black Hole or Heaviest Neutron Star? MeerKAT Uncovers a Mysterious Object in Milky Way

    An international team of astronomers have found a new and unknown object in the Milky Way that is heavier than the heaviest neutron stars known and yet simultaneously lighter than the lightest black holes known.

    Using the MeerKAT Radio Telescope, astronomers from a number of institutions including The University of Manchester and the Max Planck Institute for Radio Astronomy in Germany found an object in orbit around a rapidly spinning millisecond pulsar located around 40,000 ligh...

    PSR J0952-0607: The Fastest and Heaviest Known Galactic Neutron Star
    A spinning neutron star periodically swings its radio (green) and gamma-ray (magenta) beams past Earth in this artist’s concept of a black widow pulsar.

    A dense, collapsed star spinning 707 times per second—making it one of the fastest spinning neutron stars in the Milky Way galaxy—has shredded and consumed nearly the entire mass of its stellar companion and, in the process, grown into the heaviest neutron star observed to date.

    Weighing this record-setting neutron star, which tops the charts at 2...
