Rubin First Look Watch Parties

Rubin First Look Watch Parties were organized worldwide on June 23, 2025 to allow scientific communities, astronomy enthusiasts, and the general public to witness the release of the First Look images together. In total, 363 science centers, planetariums, schools, universities, organizations, and observatories hosted in-person and online gatherings. Held across six continents, the events attracted diverse audiences — from amateur astronomers to families and students.

Attendees enjoyed live streams of the Rubin First Look Press Conference, talks from Rubin scientists, deep dives into the First Look images, and Q&A sessions. Venues that registered to host a Watch Party were sent curated material lists to help plan their events. Some sites enhanced the experience with additional activities such as telescope viewings, student poster sessions, or guided sky tours from local astronomers. Additionally, many Watch Parties were covered by local news and institutional publications around the world and shared widely on social media.
