milkyway bg image problem

hi i have a earth scene that i got from blendswap , i put a few new objs in the scence and can see them fine in the viewport ,but when i render a image to save it a bg pic of the milkyway appears and blocks out all of my new obj’s? i like the bg image but i need to get my other obj’s into the final render, since i didn’t start this scene and im a newbie i really could use some help from someone , i think its something really simple i just cant do it,lol thanks in advance

might not be getting your objects infront of your plane. might want to check different angles, and wireframe in order to trouble shoot it
