http://www.teachastronomy.com/ Astronomy is the study of all matter and radiation beyond the earth. Astronomy is the oldest science, but it's also the science with the most adventure and excitement going on right now. Astronomers are closing in on fundamental questions about the universe we live in including the fact of whether or not we're alone as life forms, how old the universe is, what the universe contains, and the nature of the big bang itself. Astronomy is currently driven by innovations in technology that have led to new detectors, new regions of wavelength space being explored, and new telescopes on mountain tops around the Earth's surface. Astronomy is one of the most exiting sciences, and astronomers have learned about the insides of dense stars, about galaxies as they first form, and the first fractions of a second of the big bang itself.
