Science Buddies: Using a Digital Camera to Measure Skyglow
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...

Science Buddies: Changing Constellations
Do you like to look up into the night sky? There are so many stars, it can be mind boggling. Some ancient people marked time by the changes in star patterns. We still use changes in constellation patterns to mark astronomical time. This...

Science Buddies: Measuring the Moon
Sometimes a full moon can be so bright, you can walk around in the dark without a flashlight. How much brighter is a full moon than the other phases of the moon? How is the brightness of the moon measured?

Science Buddies: A Matter of Time
Do you wake up at the crack of dawn, or do you need an alarm clock to wake you up each morning? It may surprise you that the two are not always in synch. Nowadays, we use Standard Time to set our watches instead of Solar Time. Which...

Science Buddies: Sunspot Cycles
Sunspot activity has been monitored continuously since about 1700. The historical data shows that sunspot activity rises and falls in a roughly 11-year cycle. This project shows you how you can use both graphical and statistical analysis...

Science Buddies: Calculating the Circumference of the Earth
In this project, you will estimate the circumference of the earth, using a method developed about 2,200 years ago, by Eratosthenes, a Greek mathematician and the librarian of the great library at Alexandria, in Egypt.

Science Buddies: Similar Triangles: Using Parallax to Measure Distance
Want to stretch your imagination? One good way is to try to imagine how far it is to a distant star. How much farther away is it than the moon is from the earth? In this project, you'll learn one way of measuring the distance without...

Science Buddies: Observatory Satellite Measures Motion of Coronal Mass Ejection
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...

Science Buddies: Correlation of Coronal Mass Ejections With Solar Sunspot Cycle
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...

Science Buddies: Catching Stardust
How do astronomers collect stardust? They design and build satellites that are launched into space to collect particles on specially designed panels. Satellites can be sent to orbit around an object of interest: a planet, moon, or comet....

Science Buddies: Where Did All the Stars Go?
If you live in a big city or urban area it is hard to see many stars at night. In most urban areas only the most brilliant stars, planets and the moon can be seen. This is because of something called light pollution which is the...

Science Buddies: The Moon and the Stars
When you are in the city, only a few of the brightest stars are visible. But when you are in the country, you can see many more stars than you can count. Sometimes you can even see the bright belt of our galaxy, the Milky Way. In this...
