NEW YORK -- If you ever dreamed of naming a planet, here is your chance.

The James Webb Space Telescope is discovering new planets outside our solar system, and now 20 planet names are up for grabs.

Here are the rules: You can't name a world after yourself or your pet, or give it a religious or military name.

The contest is open through Nov. 14.
