Thirty Years of the Telescopio Nazionale Galileo

---

Celebrating Past, Present and Future of the Largest Italian Optical Telescope

 

2026 marks the 30^th anniversary of the inauguration of the Telescopio Nazionale Galileo (TNG) and provides an opportunity to meet for a Great Celebration and to reflect on the impact of our telescope on the astronomical community under several aspects:

• the technical and scientific achievements during these 3 decades;

• the institutional and international collaborations born to exploit its capabilities;

• the availability to students and researchers of state of the art instrumentation;

• the legacy of inspiration and values that brought together the Italian community to obtain, maintain and support a national project. 

The meeting will allow the key contributors of this 30 years long adventure to get together and highlight the role of the TNG on research and innovation. It will also be the ideal framework where to discuss the options for future direction to follow in order to maintain top level science in the years to come when ELT, Plato, HWO, Einstein Telescope and several other facilities will be available. 

The meeting will take three days, beginning on September 22^nd with the 30^th anniversary Celebration Ceremony with Political and Academic Authorities in the premises of the TNG at the Observatory of Roque de Los Muchachos. On the following two days, on September 23-24, the Scientific Workshop will be held at Palacio Salazar in Santa Cruz de La Palma, with invited speakers and oral and poster contributions. A round table with INAF governing bodies and scientific experts discussing on the future of the TNG will conclude the meeting.

Contributions

We will be pleased to accept oral or poster contributions on 3 main subjects:

• Origins and Early days

• • Memories and lessons learned from who has been there since the beginning

• Role and contribution of the TNG during these 30 years

• • Scientific and technical achievements as a front line Italian observing facility
  • The TNG as a catalyst for national and international collaborations
  • Training facility and test-bench for a new generation of astronomers

• Proposals for the future

• • New Instrumentation and technical improvements to make the TNG future proof
  • Science fields where the TNG will be able to compete for scientific excellence

 

The Meeting will be held in hybrid format, and Zoom/Meet link will be sent to registered participants attending online.

Over the past three decades, the Telescopio Nazionale Galileo (TNG) has combined world-class scientific research with a strong commitment to education and public outreach. Through educational programs, public events, guided visits, and digital communication, the TNG has promoted astronomy among students, teachers, and the general public, fostering scientific literacy and inspiring future generations.
This contribution reviews the evolution of the TNG's Education and Public Outreach activities and highlights the TNG’s collaboration with the central communication structures of INAF, including the Unità Supporto alla Comunicazione ed Educazione (USC&E), the INAF Press Office, and the Social Media Group. These collaborations have enhanced the dissemination of scientific results and strengthened the impact of outreach initiatives at the national level.
On the occasion of the TNG's 30th anniversary, this presentation reflects on the role of TNG as both a research infrastructure and a bridge between astronomy and society, while looking ahead to future opportunities for science communication and public engagement.
