So You Want To Be An Astronomer & Exoplanet Hunter: A Kids' Guide to Astronomy, Telescopes, Stars and Galaxies, and the Curious Scientists Who Search (Hardcover) (ISBN-13: 9781972766996)

From the So You Want To Be A... Series - 2026 Purple Dragonfly Book Awards, Grand Prize Winner

Somewhere right now, a space telescope is staring at a single patch of sky, tracking thousands of stars at once, watching for a flicker of dimming light so faint that one part in ten thousand counts as a signal. That flicker might be noise. Or it might be the shadow of a world no human has ever seen, crossing in front of its star hundreds of light-years away. Welcome to the work of exoplanet hunting, one of the most exciting frontiers in space science.

So You Want To Be An Astronomer and Exoplanet Hunter takes curious readers ages 10 to 14 inside this profession, not the Hollywood version but the true one: the years of physics, math, and patience before an astronomer ever points a telescope at the sky, and the painstaking art of finding planets by measuring changes in starlight too small for the human eye to catch.

Inside, you'll explore how the transit method catches a planet's shadow crossing a distant star, how spectroscopy reads the chemical fingerprints of alien atmospheres, and how radial velocity captures the faint stellar wobble that gave away the very first exoplanet. You'll learn about the space telescopes scanning whole sections of sky and the mountaintop observatories above the clouds where astronomers work through the night, collecting data on stars, planets, and galaxies far beyond our solar system.

But this book does more than explain the science. It profiles the astronomers who opened the universe to human understanding, including women who broke through institutional barriers to change what we know about dark matter, comets, and distant worlds. Three of the five featured scientists are women whose persistence reshaped the field.

The most surprising fact in these pages may be this: you don't need a degree to start hunting exoplanets. Telescope data is publicly available, and citizen-science platforms have already helped people without any astronomy training confirm planets orbiting distant stars. The book lays out practical steps you can take now: learn the constellations, try a small telescope to spot Saturn's rings or Jupiter's moons, explore datasets online, and build the math and coding skills professional astronomers use every day. A day-in-the-life section walks you through an observing night, from dome opening at sunset through calibration, a twelve-target run, weather delays, and the morning data analysis that follows.

Scattered fun facts reveal the strangeness of known exoplanets: worlds where it rains molten iron, where glass flies sideways in screaming winds, and where double sunsets light alien skies. Written in a warm, direct voice that trusts young readers with real science and real vocabulary, this book blends stargazing inspiration with a genuine space-science deep dive, and an honest look at what it takes to turn curiosity about the night sky into a life spent exploring the universe.

For the young person who looks up and doesn't just feel the wonder but wants to know what's out there, and whether we might finally answer astronomy's biggest question: are we alone?

Ages 10 to 14. Illustrated nonfiction. Science and nature.
