"Sometimes astronomers come across objects in the sky that we can’t easily
explain. In our new research, published in
Science, we report such a
discovery, which is likely to spark discussion and speculation.
Neutron stars are some of the densest objects in the universe. As compact as an
atomic nucleus, yet as large as a city, they push the limits of our
understanding of extreme matter. The heavier a neutron star is, the more likely
it is to eventually collapse to become something even denser: a black hole.
These astrophysical objects are so dense, and their gravitational pulls so
strong, that their cores – whatever they may be – are permanently shrouded from
the universe by event horizons: surfaces of perfect darkness from which light
cannot escape.
If we are to ever understand the physics at the tipping point between neutron
stars and black holes, we must find objects at this boundary. In particular, we
must find objects for which we can make precise measurements over long periods
of time. And that’s precisely what we’ve found – an object that is neither
obviously a neutron star nor a black hole."
