The Engineering Research Institute "Ventspils International Radio Astronomy Centre" (VIRAC) of Ventspils University of Applied Sciences (VUAS) continues to develop its research infrastructure by implementing the project "Modernization of the Irbene Radiotelescope Complex Phase 4" (Project No. 1.1.1.2/1/25/I/005), funded by the European Regional Development Fund (ERDF) with co-financing from the Latvian state budget. The goal of the project is to enhance VIRAC as a centre of excellence of national importance with modern and sustainable scientific infrastructure. Several significant procurements and activities have been carried out as part of the project. To ensure the storage of large volumes of radio astronomy observation data, new hard drives with double the capacity were purchased using project funding for the Irbene Flexbuff data server. The Flexbuff server is used to store radio astronomy observation (typically VLBI) data. The previous data storage capacity was no longer sufficient, as both the transmission speed of observation data and the overall data volume have grown significantly in recent years. The new drives will ensure compliance with the increasing storage requirements of the EVN and CERN Tier-2. A contract has been concluded for the procurement of a six-wheeled ATV (quad bike) and its equipment. Such a mobile vehicle makes it possible to transport and test antenna, mobile satellite communication, unmanned, and floating equipment control and immunity solutions in motion. The vehicle is capable of transporting and testing research equipment in motion across the antenna complex's territory of more than 70 hectares, including forest and marsh conditions. Providing such equipment is essential for the developed systems to reach a high Technology Readiness Level (TRL) under real-world conditions. The engineering systems developed as a result of the research and tested with this vehicle have high dual-use potential. In May 2026, a MIG/MAG semi-automatic welding machine with the necessary peripherals and a set of materials suitable for welding aluminum and its alloys was purchased. The equipment is required for manufacturing feed systems for the RT-32 and RT-16 radio telescopes in order to expand their reception bands and promote new radio astronomical observations. As part of the modernization project, a procurement for the photogrammetry and alignment of the RT-32 radio telescope antenna surface will soon be concluded to improve surface accuracy, sensitivity, and performance at higher frequencies. Currently, the efficiency of the RT-32 antenna reaches only 35–38%, and in the highest frequency bands, it is even lower, making observations practically impossible. Photogrammetric measurements will make it possible to precisely determine the necessary position corrections for each primary mirror panel and adjust the panel mountings accordingly, reducing antenna surface error. Following the antenna surface alignment, the sensitivity, measurement accuracy, and observation capabilities of the radio telescope will improve significantly across all operating frequency bands. Taking into account that on December 15, 2025, a positive decision was received from the European Commission regarding amendments to the European Union Cohesion Policy Programme for 2021–2027, granting flexibility funding for its implementation, contract amendments for the project "Modernization of the Irbene Radiotelescope Complex Phase 4" were signed in July of this year. An additional EUR 79,151 was allocated, of which 85% is ERDF funding and 15% is Latvian state budget co-financing. With the additional funding granted, further procurements are planned within the project for the development of VIRAC's research infrastructure: purchase and installation of spare asynchronous electric motors and their control systems required to ensure the sustainability of the motor drives for the RT-32 and RT-16 radio telescopes; purchase of systems necessary to ensure the sustainability of the RF chain and control systems for the RT-32 and RT-16 radio telescopes; and the purchase of a portable handheld vector network analyzer with a bandwidth of at least up to 26.5 GHz. The EU financial support received under the project "Modernization of the Irbene Radiotelescope Complex Phase 4" (No. 1.1.1.2/1/25/I/005) strengthens VIRAC's capacity to conduct high-quality radio astronomical observations and develop new, dual-use research competencies, while ensuring the sustainability and international competitiveness of the Irbene Radiotelescope Complex.

How is the Baltic blue economy changing – and what kinds of technologies, skills and decisions are needed to support its sustainable future? MarTe has published a new collection of webinar and workshop recordings on YouTube. The videos bring together researchers, industry experts and public sector representatives from Estonia and Latvia to discuss the future of the Baltic blue economy from two perspectives: the bigger strategic picture and practical technology tools.

A team of solar physicists has discovered a new way to detect and measure entropy variations in the Sun’s atmosphere – a breakthrough that could help researchers better understand how energy moves through the solar corona and why the Sun’s outer atmosphere is millions of degrees hotter than its surface. Entropy is a concept that dates back to the 1860s, when German physicist Rudolf Clausius introduced it while studying the efficiency of heat engines and the famous Carnot cycle. Since then, entropy has become one of the most fundamental ideas in physics, helping scientists describe how energy is distributed and transformed in systems ranging from steam engines and black holes to stars and even the Universe itself. Despite its importance, entropy has remained notoriously difficult to measure directly in the Sun's atmosphere. In a new study currently in press in The Astrophysical Journal Letters, researchers from the University of Warwick, the Ventspils International Radio Astronomy Centre (VIRAC, Ventspils University of Applied Sciences), and University College London have shown that entropy leaves observable fingerprints in waves that travel through the Sun's hot, magnetised atmosphere, known as the corona. "Entropy is one of the key quantities that tells us how energy is organised within a physical system," explains lead author Dmitrii Kolotkov, Stephen Hawking Fellow. "In a conceptual sense, we can think of solar active regions as natural heat engines, continuously converting and transporting energy through hot magnetised plasma. Their behaviour and efficiency are closely linked to entropy. The concept itself has deep roots in thermodynamics and even plays a central role in black hole physics, where entropy is associated with the fundamental limits of information and energy storage. When entropy remains unchanged, energy tends to stay more organised and localised. When entropy is perturbed, energy becomes redistributed and spreads through the surrounding plasma. If we can measure how entropy changes in solar active regions, we gain a new way of tracking how energy is transported, dissipated, and ultimately converted into heat."

On 18 May, the first EDI (Equality, Diversity, Inclusion) seminar, implemented within the COLOURS project, was successfully held at the café “Panorāma.” The aim of the seminar was to promote understanding of equality, diversity, and inclusion, as well as to strengthen cooperation between different groups of society. The seminar brought together 53 participants, including local students, international students, Erasmus+ students, administrative and academic staff, as well as members of the wider community. The event also attracted a broad range of participants: volunteers from the “Youth House,” city residents, secondary school students, participants of the Lifelong Learning Centre (MIC) alumni courses, and a guest lecturer from the University of Brittany in France. This diversity of participants ensured the practical implementation of the Quadruple helix principle, fostering collaboration between academia, industry, society, and the youth sector. The seminar was led by students Līva Slesare, Amanda Gintere, and Tillija Naumann, demonstrating the active involvement and leadership of young people in building an inclusive education and society. All seminar participants received a COLOURS virtual badge, serving as proof of the knowledge and skills acquired, and can be used for personal and professional development, including on LinkedIn profiles. It is planned that starting from autumn 2026, this training seminar will also be offered in an online format in both Latvian and English. This will make it accessible to a wider audience. Everyone – students, staff, and city residents alike – will have the opportunity to participate, gain knowledge about EDI, and receive the COLOURS badge. This initiative is seen both as an opportunity and a responsibility –to jointly build a more inclusive, open, and understanding society.

Ventspils University of Applied Sciences has officially adopted the COLOURS Alliance EDI Policy – a shared framework for equality, diversity and inclusion. The policy will now be adapted and implemented within the university’s operations. The aim is to strengthen inclusion across education, research, and everyday practices. The policy can therefore be seen as both a pedagogical and strategic implementation tool to prevent discrimination, increase understanding of differences, and equip students and staff to perform at their best in diverse teams. EDI stands for equality, diversity and inclusion. The training in EDI is designed to strengthen interpersonal relationships, raise awareness of the value of diversity in innovation, creativity and knowledge development, and encourage reflection on one’s own position and approach to others. The implementation of the policy contributes to the development of generic competences and critical thinking among both students and staff. This EDI policy is part of a much larger context, as we are one of nine higher education institutions in Europe adopting the same framework. EDI as a driver for an inclusive society The policy also emphasizes the importance of collaboration through the Quadruple Helix model, where universities, industry, the public sector, and civil society work together. The goal is not only to develop knowledge within EDI, but also to disseminate it and create societal impact. The policy marks the starting point for new initiatives and serves as a bridge to society. EDI strengthens the quality of education and research and is an important tool for both current operations and future needs. Signed policy is available HERE
