In a accelerated article preview in
Nature published on 16 Oct 2017,
the LIGO Scientific Collaboration and the Virgo Collaboration report
on a new measurement of the Hubble constant, Ho (H-zero),
using observations from the recent neutron star merger event.
They report Ho = 70 (+12.0/-8.0) kilometres per second per megaparsec,
which is "consistent with existing measurements, while being completely independent of them".
They also report, "Our measurements do not require any form of cosmic ‘distance ladder’;
the gravitational-wave analysis directly estimates the luminosity distance out to cosmological scales".
