An instrument that will help astronomers study dark matter and galaxies in detail has begun to be assembled at the Subaru Telescope in Hawaii.

The Metrology Camera is the first of several sub-components currently under construction worldwide to be assembled at its final destination in order to create the Prime Focus Spectrograph (PFS). When the PFS is mounted on the telescope, it will be able to measure spectra of up to 2400 celestial objects in the night sky all at once. This is important because it will help astronomers understand how stars and galaxies are distributed, and how they move around us, affected by the presence of dark matter. Studying millions of stars and galaxies across large areas of sky will therefore help create a dark matter map of our Universe.
