The 4S satellite tweet is a new feature that is coming to Instagram for a limited time.
This photo sharing feature is designed to make it easier for users to see what other users are doing and sharing.
The tweet will appear as a photo in the feed and users can swipe up on the photo to reveal a list of all the people in the photo.
If you’re new to Instagram, you can sign up for an account here to get started.
The feature is currently available in the US and the UK.
