Name : Barnard's Star|
This activity is a Keystage 4/5 activity to determine the distance of a nearby star using the parallax effect, before calculating its transverse velocity. The task involves measuring the movement of Barnard's Star in relation to two adjacent fixed stars, and then uses simple algebra and trigonometry to discover more about its motion. The measurements are done on Liverpool Telescope images of Barnard's Star taken over the past 6 years.
Age Range : 14 - 18 years
