In December 2016, the theme of the song was extended into the hour-long BBC Two "The Entire Universe" show. Written and co-presented by Idle and Professor Brian Cox, it took the form of a lecture by Cox interspersed with a "comedy and musical extravaganza with the help of Warwick Davis, Noel Fielding, Hannah Waddingham and Robin Ince, alongside a chorus of singers and dancers". The show closed with an ensemble rendition of "The Galaxy Song" with updated figures: the galaxy containing 500 billion stars instead of 100 billion; the galaxy rotation speed of 500,000 mph instead of 40,000; the galaxy thickness as 6,000 ly instead of 16,000, and a spiral arm thickness of 1,000 ly instead of 3,000.
