You need a fuel sorce for the morning star to work. Did you have any glowstone/redstone/coal in your inventory? Or a charged Klein Star? It won't work without any of those. When you right-click it will consume some of the glowstone/redstone/coal or take some charge from the Klein Star.

Hope that helps you :)
