Luke Skywalker dies in Star Wars: The Last Jedi after using the Force to project a powerful illusion of himself across the galaxy from the planet Ahch- To to the battle on Crait. This Force projection required an immense amount of energy and concentration, which ultimately drained all of his life force. After successfully distracting Kylo Ren and allowing the Resistance to escape, Luke returns to Ahch-To, where he peacefully dies and becomes one with the Force
. His death is portrayed as both a physical exhaustion from the effort of projecting himself and a spiritual acceptance of his fate, similar to how Obi- Wan Kenobi accepted his death and became a Force ghost. Luke’s final act redeems his past mistakes, particularly his failure with Ben Solo, and reignites hope for the galaxy
. After his death, Luke appears as a Force ghost in The Rise of Skywalker , guiding Rey and supporting the Resistance in their final battle against the Sith
. In summary, Luke Skywalker dies by sacrificing his physical body through an extreme Force projection, willingly becoming one with the Force in a peaceful and redemptive moment
