Astronomy Science Projects (45 results)

Astronomy is science that will challenge your imagination. How many stars in a galaxy? How many galaxies in the known universe? How many strange worlds are out there on other planets, orbiting other stars, and what are they like? Is there life on planets besides Earth? The distances are mind-boggling; the numbers are immense.

Can AI Classify Stars?
Science Fair Project Idea
Engineering Design Process
Understanding the different types of celestial objects in our galaxy is important for astronomers. It helps them study how these objects form and evolve, map the night sky, understand the structure of the Milky Way and other galaxies, and identify celestial bodies that might host habitable environments. In this project, you will create a boosted tree model to classify celestial objects based on their spectral characteristics. Read more
How Old Is the Universe?
Science Fair Project Idea
Scientific Method
Would it surprise you to learn that no one knows the exact age of the universe? Astronomers have estimates, and as they gather increasingly precise data and measurements, they continue to refine those estimates to come up with more accurate estimates. In this project, you can look at data about stars in dense groups called globular clusters and come up with your own estimate for the minimum age of the universe. How closely will your estimate match those of other astronomers? Read more
Analyzing Impact Craters on Mercury
Science Fair Project Idea
Scientific Method
Have you ever wanted to analyze data from a NASA spacecraft? In this science project you will use data from NASA's MESSENGER mission to measure the diameter and calculate the depth of impact craters on Mercury. You will then analyze that data for relationships between a crater's depth and diameter. This is your chance to perform a science project as a NASA researcher would! Read more
How Does Speed Affect Orbiting Altitude of Satellites?
Science Fair Project Idea
Scientific Method
The movement of satellites is intriguing, but how do they orbit the way they do? Aerospace engineers run calculations and set up computer models to help them predict how satellites move in space, but in this astronomy science project, you will create a physical model with marbles, clay, and a cookie sheet to help you study how satellites move in space and learn from your observations.

The Moon and Tides
Science Fair Project Idea
Scientific Method
Have you ever wondered what causes the tides in Earth's oceans? In this astronomy project, you will discover the answer for yourself! You will investigate how the Sun and Moon control tides in Earth's oceans. Read more
The Milky Way and Beyond: Globular Clusters
Science Fair Project Idea
Scientific Method
Globular clusters, compact groups of about a million stars that move around together in galaxies, are among the oldest objects found in the universe. Since they are found in most galaxies and since they've been around for so long, globular clusters have a lot to tell us about what the universe looks like now and how it got that way. Is our Milky Way Galaxy just like all the other galaxies out there? What are galaxies made of? What can we learn about the universe from looking at galaxies? … Read more
Planet Hunters TESS
Science Fair Project Idea
Scientific Method
The Transiting Exoplanet Survey Satellite (TESS) is a space telescope for NASA's Explorers program, designed to search for exoplanets using the transit method in an area 400 times larger than that covered by the Kepler mission. It was launched on April 18, 2018 atop a Falcon 9 rocket. During its two-year primary mission, it was expected to find more than 20,000 transiting exoplanets, compared to about 3,800 exoplanets known when it launched. The first light image from TESS was taken on August… Read more
Using the Solar & Heliospheric Observatory Satellite (SOHO) to Measure the Motion of a Coronal Mass Ejection
Science Fair Project Idea
Scientific Method
The sun sometimes releases huge bursts of electrified gases into space. These bursts are called coronal mass ejections (or CMEs). When CMEs are directed towards Earth they can generate auroras, the spectacular atmospheric displays also known as "northern lights" (photo by Chris VenHaus, 2001). In this project you'll use images from the SOHO satellite to measure how fast CMEs move. Read more
Star light, Star bright: How Does Light Intensity Change with Distance?
Science Fair Project Idea
Scientific Method
Have you ever looked up at the stars at night and wondered how fast they were moving or how far away they were? By studying how the brightness of a star changes with distance, you can answer those questions. In this astronomy science project, you'll create a model of starlight and use a sensor app with your smartphone to discover the key relationship between brightness and distance. Read more
Craters and Meteorites
Science Fair Project Idea
Scientific Method
Have you ever heard someone say that the moon is made of cheese? Even though the craters on the surface of the moon resemble holes in Swiss cheese, we know that this common myth is not true. Find out how craters are formed and why they are different sizes by doing this simple science project. Read more
