Others Like “Similar Triangles: Using Parallax to Measure Distance”

Science Fair Project Idea
thumbnail Did you know that ancient astronomers could measure the distance to other stars? They could also distinguish between stars and planets. How could they do that without modern technology of telescopes? See if you can discover the link between distance and perspective used to measure stars. Read more

Science Fair Project Idea
thumbnail This is a great project for someone that is interested in both stargazing and photography. Bright city lights and even the light of the full moon obscure the dimmest stars, which can make identifying constellations more difficult. This project shows you a way to measure the amount of background light (skyglow) in the night sky. It can be a great way for you to quickly compare the star viewing quality for different locations, or for the same location at different times of the year. Read more

Time Required Long (2-4 weeks)
Prerequisites You'll need a digital camera that take pictures in manual mode with exposure times of up to 15 seconds. You will need to know how to change the shutter speed, lens aperture, and ISO setting. A tripod for the camera is nice to have, but not absolutely essential. You will also need a computer.
Material Availability Readily available
Cost Very Low (under $20)
Safety Adult supervision required for night photography.
Science Fair Project Idea
thumbnail 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

Science Fair Project Idea
thumbnail Scientists have known for hundreds of years that sunspot activity waxes and wanes over a cycle that lasts approximately 11 years. In the 1970's, scientists discovered that the sun periodically blasts electrified gases into space, in huge outbursts called 'coronal mass ejections,' or CMEs. This project asks the question: do CMEs follow the solar sunspot cycle? Read more

Science Fair Project Idea
thumbnail Have you ever seen amazing, colored images of objects in space, like stars or even entire galaxies? Some of these images were originally taken with forms of radiation that the human eye cannot actually see, like x-rays. In order to create the beautiful pictures you see in the news or online, scientists have to use an image-editing program to add color to them. In this astronomy science project, you will use raw x-ray data from NASA's Chandra X-ray Observatory telescope to create amazing… Read more

Science Fair Project Idea
thumbnail 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 light meter to discover the key relationship between brightness and distance. Read more

Science Fair Project Idea
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
