How did the universe begin? Does it have an end? Answering these questions is the aim of the Subaru Prime Focus Spectrograph (PFS), which will be based at the Subaru telescope in Hawaii. Subaru is the Japanese term for the Pleiades star cluster, and the multi-million pound instrument will come into service in 2018. It will rely on PPC products to protect fiber within the Subaru PFS.
Detecting dark matter
The PFS will enable astronomers to study dark matter - the 80% of the mass in the universe that has never been directly detected, helping better understand the future of the cosmos. It will do this by measuring the motion of about one million stars in the Milky Way and Andromeda galaxies and looking at how they are distributed across a huge area of space. Due to the power of the Subaru telescope and the wavelength coverage of PFS it will allow the first true census of early galaxies, peering back in time and helping answer the question of why we are here.
