The Observation Dome was a bubble-like area on the outside hull of the JMC mining spaceship Red Dwarf, and was used for the purposes of visual stargazing by the crew. The Observation Dome appeared in two episodes of Series II, as an alternative location to the sleeping quarters, for a serious emotional talk between Rimmer and Lister. Because it was the set for poignancy and pathos, the appearances of the Observation Dome was also mostly accompanied by sad music. An updated Observation Dome served a similar function in one scene of Back to Earth / Series IX, dubbed the Memorial Dome.
