The new planetarium film-show at the Royal Observatory in Greenwich Park will take you to an asteroid in the solar system where astronauts have built a staging post for exploring deep space. Its wondrous special effects include vertiginous vistas of the endless tracts of our universe and because the 30-minute film, narrated by Alien superstar Sigourney Weaver, is projected on to the underside of a dome it becomes almost tangibly immersive. It’s the perfect introduction to the observatory’s aerospace latest exhibition Above And Beyond, which opens on May 27.
