Observing
Watch the Moon hide naked-eye star Zeta (ζ) Tauri on 19 October
When a nearby astronomical body passes between the observer and a more distant object, see say that an occultation is taking place. Since the Moon is our nearest celestial neighbour, it regularly passes in front of planets and stars. Observers in the British Isles can see naked-eye star Zeta (ζ) Tauri glide behind the Moon on Saturday, 19 October 2019.
