Wow, it’s a hot day! A cold glass of water would be perfect right now. Have you ever thought about how amazing our Sun is? Even though it’s far away in space, it can make us feel so warm here on Earth!
Have you ever wondered what the Sun is made of? It’s a star, but how do we know what’s inside it when it’s so far away and too hot to touch? Well, we can thank a brilliant scientist named Dr. Cecilia Payne-Gaposchkin for figuring that out!
Back in the 1900s, people thought stars like the Sun were made of the same stuff as Earth, just hotter. They believed stars had a lot of iron, a heavy material found in rocks. But Cecilia Payne, who loved science from a young age, changed all that.
Cecilia was born in England and dreamed of becoming an astronomer, someone who studies space. But back then, universities in England didn’t allow women to study space. So, Cecilia moved to the United States in 1923 to attend Radcliffe College, a school for women taught by Harvard professors.
In just two years, Cecilia discovered that astronomers were wrong about what stars are made of. She used a special telescope to look at the colors of light from the Sun. Even though sunlight looks white or yellow, it’s actually made of many colors mixed together, like a rainbow!
Cecilia used these colors like a secret code to figure out the Sun’s composition. She found out that stars like the Sun are mostly made of hydrogen and helium, not iron. Hydrogen is a common element on Earth, and helium is what makes balloons float!
At just 25 years old, Cecilia earned a PhD, the highest college degree, and became Dr. Cecilia Payne. She was the first person to earn a PhD in astronomy from Radcliffe College. However, many astronomers didn’t believe her findings at first, partly because she was a woman. But Cecilia never gave up, and eventually, everyone recognized her groundbreaking work.
In 1956, Dr. Cecilia Payne-Gaposchkin became the first woman full professor at Harvard University and led the astronomy team. Today, she’s remembered as the incredible astronomer who discovered what stars are made of, changing our understanding of space forever.
Dr. Payne’s story shows that if you believe in yourself and work hard, you can achieve amazing things. So, let’s enjoy the Sun and remember the incredible discoveries of Dr. Cecilia Payne-Gaposchkin!

Colorful Sunlight Experiment: Let’s explore how sunlight is made of different colors, just like Dr. Cecilia Payne did! On a sunny day, take a glass of water and a white piece of paper. Hold the glass of water above the paper and let sunlight pass through it. Watch as a rainbow appears on the paper! Discuss with your friends or family what colors you see and why you think they appear.
Star Composition Craft: Create a model of the Sun using craft materials. Use yellow and orange paper to represent the Sun’s outer layers. Inside, use cotton balls or small balloons to represent hydrogen and helium, the main elements Dr. Cecilia Payne discovered in stars. Explain your model to someone at home, telling them what each part represents.
Imagine Being an Astronomer: Pretend you are an astronomer like Dr. Cecilia Payne. Draw a picture of what you think the Sun looks like up close. Write a short story about a day in your life as an astronomer. What tools do you use? What exciting discoveries do you make? Share your story with your class or family.
