New Astro-polarimeter Sees First Light at the Nordic Optical Telescope – Enables More Accurate Observation of Celestial Objects


Astro-polarimetry is an important method in astronomical observation, aimed at detecting and measuring polarisation of light emitted, reflected, or scattered by astronomical objects such as asteroids, planets, nebulae, stars and exoplanets.  The astro-polamiter built with the lead of a research group from the University of Turku made its first observations in July 2019 at the Nordic Optical Telescope on the Canary Islands. In October 2019, the University of Turku becomes the joint owner of the Telescope.
