Chinese scientists calculate the Milky Way's mass as 805 billion times that of our Sun

ALSO: Australia says offensive hacking is working; DJI hit with $279m patent suit; Philippines Police leak data; and more

Asia In Brief Chinese scientists have estimated the mass of the Milky Way.

To do so the authors considered 260,000 stars – a larger number than has previously been used for a study of this type – many of them identified by the European Space Agency's GAIA observatory. GAIA was designed to observe distant stars with greater precision than has previously been possible.

As detailed in a paper in The Astrophysical Journal, researchers from the National Astronomical Observatories of the Chinese Academy of Sciences conducted a survey of our galaxy and measured its rotation curve – the orbital speeds of visible objects compared to their radial distance from the galaxy's center.

The study also considered dark matter and came up with the figure of 805 billion solar masses as the likely mass of the entire Milky Way. Which is quite a lot and would ruin your appetite if you ate a whole one.

According to the National Observatories, the paper's reviewers hailed the research as the most accurate to date.
