MAGIC Telescope System Detected Energetic Gamma-ray Emission from a Nova Eruption – Observation Provides New Insights into the Origin of Cosmic Rays


Using the telescopes of the MAGIC collaboration, scientists have detected very-high-energy gamma rays from the nova eruption of the RS Ophiuchi recurrent nova on the Milky Way.  The measured radiation is up to one hundred billion times more energetic than visible light. This is the first time such intense gamma rays have been observed from a nova. The observations provide new insights into the role of nova eruptions as sources of the mysterious cosmic rays.

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.
