Space and astronomy news
Anytime astronomers talk of mapping the Milky Way I am always reminded how tricky the study of the Universe can be. After all, we live inside the Milky Way and working out what it looks like or mapping it from the inside is not the easiest of missions. It’s one thing to map the visible matter but mapping the dark matter is even harder.
The international scientific journal Nature Astronomy recently published the paper “A slightly oblate dark matter halo revealed by a retrograde precessing Galactic disk warp.” This research, jointly led by the University of Chinese Academy of Sciences, Peking University, the National Astronomical Observatory of the Chinese Academy of Sciences, and Shanghai Jiao Tong University, introduced an innovative “motion picture” method to measure the precession rate of the Milky Way’s disk warp.

'Motion-picture' method reveals shape of the Milky Way's dark matter haloAn international team has pioneered a 'motion-picture' method for measuring the precession rate of the Milky Way's disk warp. Using a sample of Cepheid variable stars of different ages, this method allows the precession direction and rate of the Milky Way's warp to be clearly observed.
