We’re approaching an incredible milestone on Zooniverse: 1 BILLION classifications.
Every classification, transcription, drawing, tag and click made by more than 3 million volunteers across Zooniverse projects has helped researchers answer questions that would otherwise be impossible to answer at this scale.
Watch the countdown
To celebrate the countdown, we’ve created a live classification counter, so visitors can watch us get closer to 1 billion classifications in real time. Count down with us here: https://www.zooniverse.org/about#zooniverse-billion.
This milestone belongs to the entire Zooniverse community. Whether you joined recently or have been classifying with us for years, thank you for being part of it.
We want to hear from you!
As we get closer to 1 billion classifications, we’d also love to hear from you.
Do you have a favourite Zooniverse project? A memorable discovery? A story about what participating in Zooniverse has meant to you over the years?
Share your favourite projects, discoveries, memories or stories on Talk. We’d love to hear what Zooniverse has meant to you over the years, and we may feature some community responses during our 1 billion celebrations later this year.

I believe we had a similar counter some years ago.
