So You Want To Be An Astronomer & Exoplanet Hunter (So You Want To Be A...)
About
The telescope clicks into position. The data starts flowing in — a star’s brightness, recorded thousands of times over thousands of nights. Most of the readings are flat. But every so often, the light dips by a fraction of a percent for a few hours and then returns to normal. To anyone else, it would look like noise. To the astronomer watching the screen, it’s the shadow of a planet — a world no human has ever seen — passing in front of its star, hundreds of light-years away.
So You Want To Be An Astronomer / Exoplanet Hunter takes young readers ages 10–14 inside one of the most patient and most genuinely revolutionary professions in all of science — not the dramatic-discovery version, but the real one. The years of physics and mathematics that happen before an astronomer ever points a telescope at the sky. The specific discipline of finding new worlds by measuring changes in starlight so small the eye could never detect them, and trusting the math to show what the eye cannot. The team of observers, instrument scientists, and theorists working in coordination so that a signal lasting a few hours and crossing hundreds of light-years arrives in a dataset clean enough to interpret. The detection that confirms a new planet — and the one that, after months of analysis, turns out to be a flicker in the instrument and sends everyone back to the data.
This is a book about what astronomers actually do: the long observation runs they plan years in advance to gather light from objects so distant the photons left before humans existed, the spectroscopy they use to read the chemical fingerprints of stars and atmospheres and learn what worlds are made of without ever visiting them, the data analysis they perform on tens of thousands of stars at once to find the rare few showing the dimming of a transiting planet, and the careful follow-up across multiple instruments to make sure a discovery is real before announcing it. It’s also a book about what the work demands, what it offers, and why the people who do it say that the most thrilling moment in science is not certainty but the quiet instant when the data first suggests something is out there.
Inside, young readers will discover:
- What a real astronomer’s research and observing life actually looks like — from telescope time proposals to night-sky data collection to the long process that turns raw light into discovery
- The science of how we find exoplanets — transits, radial velocity, direct imaging, gravitational microlensing — and the physics that makes detecting worlds light-years away possible
- The intellectual demands the profession requires — and how astronomers build the mathematical fluency, the patience, and the scientific imagination to meet them
- The history of astronomy and the legendary scientists whose curiosity and persistence opened the universe to human understanding
- What young people can do right now to discover if this might be their calling
Honest, specific, and genuinely illuminating, So You Want To Be An Astronomer / Exoplanet Hunter doesn’t talk down to young readers — it brings them all the way in. Because the child who wants to know what this work is really like deserves a real answer.
For readers who feel the pull toward something that demands total mathematical rigor and total imaginative reach in the same breath. For the kid who looks up at the night sky and doesn’t just feel the wonder — they immediately wonder what’s out there, and how we could possibly know.
Every confirmed exoplanet, every mapped galaxy, every new understanding of the universe began with someone who turned curiosity into a discipline. Who learned the math, mastered the instruments, and waited for the light. Maybe that someone will be you.

Praise for this book
"So You Want To Be An Astronomer & Exoplanet Hunter is one of the more unique jobs in the So You Want To Be series by Linda Soules. Although it might seem like astronomers spend all night gazing through a telescope, there’s much more to this job than meets the eye. This is a real eye-opener into what they do, how they discover worlds that no one has ever walked on before, let alone seen, and what it takes to be that person. You’ll learn about the years of training before you even look through a telescope, how to understand what you see through it, and what you need to do your job. You’ll understand the team they work with, how they analyze what they spot, the instruments they need, and you’ll get to visit amazing worlds you’ll never see in person. Walk in an astronomer’s shoes to understand why it’s one of the most exciting jobs in the world and beyond.
So You Want To Be An Astronomer & Exoplanet Hunter by Linda Soules is part of an amazing series that helps kids of all ages decide what they might want to do for a job. Packed with clearly written scientific facts, this is a wonderful book that takes readers on a stunning journey through an astronomer’s life. Astronomy isn’t just about peering at the sky through a telescope; it’s about the joy of discovering exoplanets and of learning to understand a whole new, largely undiscovered world above us. The illustrations are lovely, helping explain things, and you’ll meet some famous astronomers and learn what they discovered. And if you want to get started right now, there are some practical steps to follow at the end, along with an informative glossary. If you’ve ever gazed up at the sky and wondered what’s beyond, wonder no more. This book is the perfect introduction to a fascinating job."
"So You Want To Be An Astronomer & Exoplanet Hunter is a fascinating and beautifully presented nonfiction book for young readers who are curious about space, science, and what it really means to study the universe. Written for ages 10 to 14, this book goes beyond simple stargazing facts and gives readers an honest, exciting look at the real work astronomers do, especially those who search for planets beyond our solar system.
One of the book’s greatest strengths (as it is in the entire So You Want To Be… series) is the way it explains complex science in a clear and engaging way. Readers learn how astronomers detect exoplanets by studying tiny dips in starlight, measuring the wobble of distant stars, and using spectroscopy to understand the chemical makeup of alien atmospheres. These are big scientific ideas, but Soules presents them in a way that feels approachable without talking down to kids. The book trusts young readers with real vocabulary and real science, which makes the subject even more exciting.
The career-focused sections are especially strong. The book does an excellent job of showing that astronomy is not just about looking through telescopes. It involves math, physics, coding, patience, careful observation, data analysis, and problem-solving. And above all, it takes patience, as Linda puts it, “the timescales are humbling. An exoplanet… is found only by observing its star for at least one full orbit – which means years of patiently waiting.” The day-in-the-life section gives readers a realistic look at an astronomer’s work, from opening an observatory dome at sunset to dealing with weather problems and reviewing data the next morning. This realistic approach makes the career feel both challenging and inspiring.
The illustrations are another highlight. They are colorful and detailed, adding visual interest while also helping explain the science. The book also includes fun facts, a helpful glossary, historical profiles of important astronomers, and practical suggestions for kids who want to start learning more right away. Tips such as learning constellations, visiting a planetarium, trying a small telescope, exploring real datasets, and participating in citizen-science projects make the book feel empowering.
I also appreciated the strong representation of women in science. By highlighting female astronomers who made major contributions despite facing barriers, the book shows young readers, especially girls, that they belong in science too. This adds an important and inspiring layer to an already excellent educational book.
So You Want To Be An Astronomer & Exoplanet Hunter is an informative, engaging, and visually appealing guide for children interested in space or science careers. It’s short and accessible, but still packed with meaningful information. Young readers who dream of studying stars, galaxies, telescopes, or distant planets will find this book both exciting and useful. It’s a wonderful choice for upper elementary and middle-grade readers, classrooms, libraries, and families with kids who look up at the night sky and wonder what else might be out there."
"Linda Soules turns a child's late-night wonder about the stars into a clear career guide. This exoplanet hunter volume does not talk down to readers. It invites them into real science with patience, honesty, and scale.
The guide succeeds because Soules never underestimates her audience. She walks through transit methods, all-night observatory shifts, and citizen science on Zooniverse without simplifying the hard parts. Some younger readers may need a pause at the scale of numbers involved, though the comparisons usually carry them through. As a parent, I read the 'prepare right now' section with my ten-year-old and we ended up opening a star-map app that same evening. The practical steps landed better than I expected.
Soules writes like someone who respects young minds. As part of the So You Want To Be A... series, this volume keeps the same direct, conversational tone as its companions. Her sentences carry real numbers alongside vivid comparisons that stick, and the full-color illustrations help readers picture observatory domes, transits, and far-off worlds without losing the thread. The author note at the end lands with quiet force. The voice stays warm, precise, and steady throughout.
If your child keeps asking whether anyone else is out there, this is a solid place to start. It rewards curiosity without promising an easy path into the field."
"This is an absolutely wonderful book for all ages honestly. The way that the job of an astronomer is broken down into not only what it is, but also the tools they use, the locations that are relevant to their study, and the setbacks that one can face were all very interesting to read. I had not heard of the sub-job of Exoplanet hunting either so that was something new I learned. I also love the illustrations, not only are the beautiful but they also offer a lot of information themselves. Other parts that stood out to me were the timeline of a day in the job of astronomy, as well as the information about famous astronomers from history, as well as a list of ways to learn even more. Overall, this book contained a lot of really great information and was a delight to read."
"This book was very informative and actually easy to understand. My niece is obsessed with space. So I can’t wait to show her this book to give her more information to learn about the stars and planets and the people behind it."
"I got this one for my nephew. He’s always loved and been interested in space. This book is not only detailed in a kid friendly way but the graphics are excellent. I look forward to many other topics in this line of books."
"As a mom to a little girl this book was very informative. I love the females in science representation that is displayed through out this beautiful book. It gives a very realistic picture of what this job may entail including the harder parts."
"An excellent read if you have a child interested in space and careers in the field. The book provides a great explanation of the career paths, tools, and what to expect in the types of jobs. The pictures are detailed and colorful. Good informational read geared towards upper elementary age."
"Very informative for kids and I love the pictures. Explaining the tools used for the job and the day in the life would definitely help a child to understand what an astronomer actually does. I also like that it gives tips on where a child can start today (borrow a small telescope, visit a planetarium, etc.) Very good book - short and to the point but full of good info."
"I think this book was really amazing. It told about the planets and the steps to becoming an astronomer in such easy to read and concise sentences. And it helps that the pictures were gorgeous."
"Informative book to exploring a future in astronomy. Glossary is helpful & fun facts are actually fun. If your child is exploring astronomy as a future path this book covers it all & is an in-depth introduction."
"A really cool book for kids who want to learn about astronomers. The pictures also show nice detail and lots of information on the topic. I would definitely recommend this book to elementary aged school kids!"
"This book was a delight to read. While it is written for children, it does not talk down to them. The images are well-chosen and engaging. From the coverage of the newer research area of exoplanet hunting to the helpful glossary, this book is informative and gives kids a realistic look at what astronomy is and what it takes to get into the field. The section on how a child can start immediately is a nice bonus that will interest families as well."
"The book was very informative and actually easy to understand. My son is obsessed with space. So, when he sees this book, it will blow his mind. this book will give him more information to learn about the stars and planets and the people behind it. The pictures are detailed and colorful short but an absolutely wonderful book for all ages."
"This book is a surprisingly good read even for adults. Most adults don't know a lot of professions other than their own. This book was a real eye-opener for me.
I had no idea that astronomers worked nights (although it makes sense now.) Or that they often worked at altitude. Or that it can takes years to assemble a full set of data for an exoplanet. But that all comes out in this book. I can only imagine what it would be like as a 12 year old to be getting this breadth of information.
I wonder if this could be integrated into a middle school curriculum. I remember visiting my daughter's school for a career day but there was nowhere near a complete list of professions represented."
