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.

Researchers Managed to Model Violent Flares in Centre of Black Hole System


An international team of astronomers has used the optical HiPERCAM camera of the Gran Telescopio Canarias in La Palma and NASA’s NICER X-ray observatory aboard the International Space Station to create a video of a growing black hole system at an unprecedented level of detail. The study has increased scientific understanding on the immediate surroundings of black holes.
