In this astronomy science fair project, investigate how the earth's axial tilt creates seasons. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and introduction, followed by a section on...

The Milky Way is the edgewise view of our home galaxy, a disk made up of billions of stars. The Sun resides on one of the spiral arms of the disk, 30,000 light-years from the thick hub of the galaxy. The actual center, with a black hole...

Discusses the evolution of ideas about the cosmos, from the Magic Cosmology of the Neolithic age to the stage of Mythical Cosmology, to the Geometric Cosmology of the ancient Greeks. The third stage advocated a rational approach to...

Investigate the field of astronomy in this book by Sten Odenwald where he talks about his own and others' experiences, as well as his experiences doing research.

This project shows you how to use images from an orbiting observatory to measure how fast the Sun rotates.

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...

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 most galaxies and since they've been around for so long, globular...

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.

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...

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...

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...

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 Update offers daily podcasts to supplement science exploration. Be educated and entertained while learning about astronomy, geology, wildlife, plants, and other science topics. Grab the latest podcasts, or browse the archives by...

Kids learn about sunspots, solar winds, and solar flares in the science of astronomy. What they are and how they affect Earth.

Infrared light lies between the visible and microwave portions of the electromagnetic spectrum. Infrared light has a range of wavelengths, just like visible light has wavelengths that range from red light to violet.

What is the Sun made of? How does the Sun make sunlight? Is the Sun a star?
