On 28th  November 2016, the International Union of Pure and Applied Chemistry announced that the elements 113, 115, 117, and 118 are now formally named.

The name nihonium with the symbol Nh for element 113 was proposed by the discoverers at RIKEN Nishina Center for Accelerator-Based Science (Japan); the name came from Nihon which is one of the two ways to say “Japan” in Japanese, and literally mean “the Land of the Rising Sun”.

Moscovium, with the symbol Mc, for element 115 and tennessine with the symbol Ts for element 117 were proposed by the discoverers at the Joint Institute for Nuclear Research, Dubna (Russia), Oak Ridge National Laboratory (USA), Vanderbilt University (USA) and Lawrence Livermore National Laboratory (USA). Both are in line with tradition, honoring a place or geographical region. Moscovium is in recognition of the Moscow region and honors the ancient Russian land that is the home of the Joint Institute for Nuclear Research, where the discovery experiments were conducted using the Dubna Gas-Filled Recoil Separator in combination with the heavy ion accelerator capabilities of the Flerov Laboratory of Nuclear Reactions. Tennessine is in recognition of the contribution of the Tennessee region of the United States, including Oak Ridge National Laboratory, Vanderbilt University,and the University of Tennessee at Knoxville, to superheavy element research.

Lastly, in line with the tradition of honoring a scientist, the name oganesson and symbol Og for element 118 was proposed by the collaborating teams of discoverers at the Joint Institute for Nuclear Research, Dubna (Russia) and Lawrence Livermore National Laboratory (USA) and recognises Professor Yuri Oganessian (born 1933) for his pioneering contributions to transactinoid element research. His many achievements include the discovery of superheavy elements and significant advances in the nuclear physics of superheavy nuclei including experimental evidence for the “island of stability”.

EU Space Awareness: Inspiring a new generation of Space Explorers

The EU Space Awareness Project [EUSPACE-AWE] – funded by the European Union’s Horizon 2020 Research and Innovation programme – uses the excitement of space to attract young people to science and technology and to stimulate European and global citizenship. The main goal of the project is to increase the number of young people that choose space-related careers.
