We now know of hundreds of planets outside of the solar system, ranging from giant planets with masses much greater than Jupiter's to worlds only a few times more massive Earth. But where do the planets we know best fit into this menagerie of new worlds? Are there planets like Earth elsewhere in the galaxy? Webb will help astronomers answer these questions.
These videos were developed to highlight the science that will be peformed by the James Webb Space Telescope.
