Objects are visible when light waves after reflection go into the eyes. Image is formed of the object that reflects or refracts light. Light waves have a fixed speed. So, they cover a certain distance in fixed time. Light from distant stars take a lot of time(light years) to reach us. Then light from them is perceived by us.
During their propagation, many light waves from other distant stars are moving and reach us according to their distance from us.
