Yuri's Night is observed annually on April 12 and is known as The World Space Party. This day commemorates the achievements of humanity in space exploration, particularly celebrating Yuri Gagarin, the first human to travel into space. The event encourages global unity through music, art, science, and culture, aiming to inspire individuals to pursue their dreams and promote peace. Celebrations can vary widely, including techno parties at NASA centers, movie screenings, stargazing events, and casual gatherings among friends. Yuri's Night also features live webcasts with guests such as artists, astronauts, and scientists, fostering a sense of community and encouraging science literacy. The initiative, started by Loretta Hidalgo Whitesides and others, supports event organizers worldwide with resources and publicity to enhance participation.
