On 26 May 2026, a joint press conference was held in Santa Cruz de La Palma, Canary Islands (Spain) with representatives from the CTAO Central Organisation (CTAO ERIC), the CTAO LST Collaboration, the Cabildo de La Palma, and the Instituto de Astrofísica de Canarias (IAC) to underscore the CTAO project’s advancement towards groundbreaking science and to announce the upcoming inauguration of the four Large-Sized Telescopes (LSTs) on 15 October 2026 at the CTAO-North site.

A collaborative team jointly led by Prof. YIN Zongjun from the Nanjing Institute of Geology and Palaeontology of the Chinese Academy of Sciences (NIGPAS), together with Profs. SHEN Bing and ZHOU Jihan from Peking University, has conducted systematic studies of impact-glass particles associated with Chang'e-5 lunar regolith grains.

An international experiment that has already broken several records. The KATRIN project (KArlsruhe TRItium Neutrino Experiment), led by KIT–Karlsruhe Institute of Technology in Germany and involving 20 institutions from seven different countries, including the Politecnico di Milano, celebrated the achievement of 1,000 days of neutrino measurements with the inauguration of phase 2 of the project: the commissioning of a new and more sophisticated detector, TRISTAN. The RadLab group of the Department of Electronics, Information and Bioengineering – DEIB at Politecnico di Milano, led by professors Carlo Fiorini and Marco Carminati (the latter being the national coordinator for the experiment), also supported by the National Institute for Nuclear Physics, made a significant contribution to the creation of the new detector by designing and developing the detection modules and the low-noise, highly compact readout electronics of the SDD detector.

Student teams from Monta Vista High School in Cupertino, California, and Sierra Vista Middle School in Irvine, California, took top honors at the 42nd Annual Science Olympiad National Tournament at the University of Southern California on Saturday, May 23, 2026. This is the second time that Monta Vista High School has captured the title and adds a back-to-back championship for Sierra Vista Middle School. 

The LIGO–Virgo–KAGRA Collaboration released today a new catalog of gravitational wave events. A total of 161 events, detected between April 2024 and the end of January 2025, have been added to the collection, bringing the total number of gravitational wave signals detected to date to 390. Among the most significant findings are: evidence for the existence of second-generation black holes, the most precise sky localization ever achieved for a gravitational wave source, and the clearest gravitational wave signal ever recorded.
