Instagram on Wednesday announced it now has more than 300 million active users. With that number, the photo-sharing platform has officially passed Twitter, which has about 284 million users, according to Re/code.
To celebrate the milestone, Facebook CEO Mark Zuckerberg posted this picture of him and Instagram CEO Kevin Systrom posing in a space called the "gravity room," located in the Instagram building at Facebook headquarters.
"Congrats to the Instagram community for reaching 300 million people! Here's a photo of Kevin and me celebrating in the Instagram gravity room," Zuckerberg's caption reads.
