The 'Open Science' event, hosted by the National Center for Research in Energy and Materials (CNPEM) in Campinas, Brazil, is set to take place on May 29 and 30. This initiative offers the public a unique chance to explore one of Brazil's most advanced scientific complexes, which includes the Sirius particle accelerator—the world's second 4th generation synchrotron light laboratory. The event has gained significant popularity, with 38,000 visitors recorded in 2025, reflecting the public's growing interest in science and technology.

A key aspect of this year's event is that participants must register in advance to secure a free ticket, thereby emphasizing the importance of planning for visits. On May 29, access will be exclusively granted to school groups, underscoring CNPEM's commitment to fostering science education among young students. Registration will be open from March 2 to March 15, 2026, allowing ample time for schools and individuals to prepare.

By showcasing cutting-edge research facilities, including biotechnology and nanotechnology labs, the 'Open Science' event serves not only as an educational opportunity but also as a means to inspire future generations of scientists. The structure has received endorsements from astronauts, highlighting its significance in the scientific community. Overall, this initiative reinforces Brazil's position as a leader in scientific research and education, making advanced knowledge accessible to the public in an engaging and informative setting.
