This oil painting by the Belgian marine artist François Etienne Musin (1820–1888) refers to HMS ‘Erebus’s’ Arctic venture under the command of Sir John Franklin in 1845. For Franklin’s last journey she had been fitted with a steam engine and a screw propeller and was accompanied by HMS ‘Terror’. In 1848 both vessels were abandoned in the ice.

This collage highlights a small selection of regions of the Milky Way imaged as part of the most detailed infrared map ever of our galaxy. Here we see, from left to right and top to bottom: NGC 3576, NGC 6357, Messier 17, NGC 6188, Messier 22 and NGC 3603. All of them are clouds of gas and dust where stars are forming, except Messier 22, which is a very dense group of old stars.
