An explanation of why Earth is able to sustain life begins this account that goes on to discuss the search for other exoplanets that may also be capable of supporting life. What life on another planet might look like could range from something somewhat familiar to something completely unknown, however. The clear, accessible primary text is supplemented by brief information on exoplanets and powerful telescopes that is further amplified in a note at volume’s end. The illustrations add another dynamic element as they follow a fictional African American girl and her family on a trip to a science museum. The girl, clearly fascinated by space, imagines herself as part of each exhibit. On returning home, a copy of Goldilocks and the Three Bears lies on the floor beneath her bed, and a telescope awaits. (Ages 7–11)

Do you wonder
if humans
are the only beings who wonder
if they are alone
in the universe?

Our sun is a star.
In the night sky are all kinds of stars,
and orbiting those stars
are planets like the ones in our own solar system.

Could those planets have life
like we do on Earth?

Planet Earth is not too big,
not too small, not too hot,
and not too cold. It’s just right.
Our very own Goldilocks planet . . . .

Follow a young girl
as she explores these questions
in this gorgeous book about the wondrous search
for another Goldilocks planet.
