Work Package 4 (WP4) of the AHEAD2020 project focuses on public outreach, with the aim of bridging the gap between cutting-edge high-energy astrophysics research and the broader public. By fostering awareness, inspiring curiosity, and encouraging collaboration, WP4 has made significant strides in promoting science education and engagement across Europe and beyond.

Objectives
WP4 is guided by four key objectives:

• Boost: Inspiring young people to pursue careers in astrophysics and related technologies.
• Awareness: Educating the public, students, and educators about high-energy astrophysics’ background and latest discoveries.
• Dissemination: Sharing AHEAD2020’s scientific and educational resources widely.
• Collaborations: Highlighting the importance of global partnerships in advancing scientific knowledge.

Activities and Methods

WP4 has utilized a diverse set of tools and initiatives to engage various audiences, ensuring its outreach efforts are impactful and far-reaching.

• Digital Presence:
  AHEAD2020 has established a dynamic online presence through its official webpage, ahead.astro.noa.gr, and social media platforms. These channels provide access to events, educational materials, scientific articles, and updates about high-energy astrophysics. Campaigns such as #WhatIsAHEAD2020 and #WhoIsAHEAD2020 have increased public interest and visibility.
• Educational Material:
  A wide range of educational resources has been developed, including short videos, posters, and a web-based quiz game. These materials make complex astrophysical concepts accessible to learners of all ages.

• Immersive Experiences:
  Innovative tools like the “Big Bang Machine” provide hands-on opportunities to explore astrophysical phenomena. Dome videos, translated into more than 15 languages, have been distributed to over 200 planetariums worldwide, reaching 8.5 million viewers annually.

• Events and Workshops:
  AHEAD2020 has hosted open days, summer and winter schools, and European Researchers’ Nights, bringing high-energy astrophysics to thousands of participants. These events have featured VR experiences, live demonstrations, and engaging talks, blending education with entertainment.

• Cross-Disciplinary Initiatives:
  Projects such as the “Multi-wavelength Astronomy Art Room” and collaborations with theatre and music have merged STEM, art, and culture to offer unique learning experiences. Events like the OUT THERE Festival integrated scientific concepts with artistic expression, attracting a broad audience.
• Inclusivity-Focused Programs:
  Special programs have targeted disadvantaged groups, including children in underserved areas, individuals in prisons, and participants in mental health programs. These initiatives demonstrate WP4’s commitment to reaching diverse communities and promoting equality in science engagement.
• Collaborations:
  Partnerships with European institutions and participation in EU-wide programs, such as the International Master Classes in Astrophysics (CLAXSON), have broadened the scope of WP4 activities. These collaborations have allowed for the sharing of knowledge and best practices in science communication.

Impact and Outcomes
WP4 has reached tens of thousands of individuals, from students to educators, through AHEAD2020 activities. Interactive tools and cross-disciplinary approaches have enhanced STEM education, making it innovative and engaging. Dome videos produced by the project have won international awards and featured prominently at major events, blending science and art to captivate global audiences. Inclusive engagement efforts, such as “Astrophysics in Prison” and programs for disadvantaged communities, underline WP4’s commitment to diversity and inclusion.

Collaborative Success
Through partnerships with institutions such as ESO, INAF, and others across Europe, WP4 has fostered a culture of collaboration that has enriched public outreach efforts. The “Sharing AHEAD 2022” conference further strengthened this network, exchanging best practices in science communication.

WP4 of AHEAD2020 exemplifies the transformative potential of public outreach in science, ensuring that high-energy astrophysics is not confined to research institutions but shared with and celebrated by society at large. Moreover, the initiatives undertaken as part of WP4 have created a lasting legacy. For instance, the six summer and winter schools for children organized by NOA have established a framework to inspire future generations. Even as the AHEAD2020 project concludes, these activities will continue in the coming years, sustaining the momentum for engaging and educating the public about astrophysics.
