To learn more about this topic, visit the following web sites:

Structure of the Sun

A Look Inside Our Nearest Star! Montana State University
Find out more about the interior structure of our nearest star. This page features a brief introduction with links to separate pages on different parts of the sun.

Solar Radiation, National Snow and Ice Data Center
Read this primer on solar radiation and learn about the factors that modify the role solar radiation plays in the Earth's energy budget.

The Earth's Energy Budget

Earth's Energy Balance, EOS Terra Mission NASA
This article focuses on the overarching priorities of the Earth Observing System. Please notice this is a pdf file.

Earth's Energy Budget, Oklahoma Climatological Survey
Follow along with a two page description of the balance between the amount of energy absorbed into and released out of the Earth's system.

Harmful Solar Radiation

Ultraviolet Radiation, NAS - NASA
Learn more about the health risks from ultraviolet radiation.

Sunlight, Ultraviolet Radiation, and the Skin, National Institutes of Health
A report from 1989 that addresses, among other issues, what are the sources of ultraviolet radiation, and is the extent of human exposure changing over time?

Ozone Depletion, EPA
Navigate through a web site dedicated to the topic of ozone depletion. In particular, check out the Ozone Science Fact Sheet to review some basic facts.

Sunspots and Solar Flares

Solar Flare Theory, Goddard Space Flight Center - NASA
The purpose of this page is to provide some general information about solar flares, a "feel" for scientific research into the energetic emissions from flares, and a glance into the future of solar flare research.


Inquiring Further
