AstroDay East 2026 Brings World-Class Science to the Heart of Hilo
On Saturday, May 2, Prince Kūhīō Plaza in Hilo was transformed into a lively hub of science, discovery, and community as more than 30 organizations came together for the 24th annual AstroDay East. Hosted by Maunakea Observatories, the free, family-friendly event welcomed keiki and families for a full day of hands-on learning, live demonstrations, and interactive fun.
From the start of the day, the plaza was filled with energy as attendees explored exhibits ranging from astronomy activities to robotics displays. Scientists, educators, and students shared their work directly with the community, offering a closer look at the research and technology happening right here on Hawaiʻi Island.
“AstroDay is one of my favorite days of the year because it belongs to everyone. This is our chance to bring world-class science into the heart of our community and inspire the next generation of scientists, explorers, and dreamers,” said Carolyn Kaichi, education and outreach specialist at the University of Hawaiʻi Institute for Astronomy. “We do this especially for the keiki who may one day carry that legacy forward.”
Throughout the day, visitors collected AstroDay coins for a chance to win prizes, while the mid-mall stage featured live showcases and award announcements, with radio coverage helping keep the momentum going. Characters from the Pacific Outpost of the 501st Legion added to the excitement, offering photo opportunities and memorable interactions for guests of all ages.
One of the highlights of the event was the return of the Robot Rumble, presented by the Hawaiʻi Science and Technology Museum (HSTM), where teams from across the island competed in fast-paced matches. Nearby, local students showcased their own robotics projects, reflecting the growing strength of STEM education across Hawaiʻi Island.
Adding to the spirit of student achievement, the East Hawaiʻi Island Science Fair organizers displayed a selection of science fair projects, giving attendees a chance to see the impressive research and experimentation carried out by local students. The showcase highlighted the breadth of scientific curiosity thriving across the island’s schools.
