Vera Rubin Telescope (aka LSST) is finally ready. We're expecting first light in the coming months. It will find Planet 9 (if it exists), discover thousands of new asteroids, millions of new supernovae and will change the way we do astronomy with its surveys of the night sky. Here's how it will do all that.
