Using small telescopes around the world, Global Telescope Network members observe and analyze astronomical objects related to the NASA Fermi Gamma-ray Space Telescope (formerly GLAST), Swift, and XMM-Newton missions. These missions are designed to study astronomical objects through their emission of x-rays and gamma rays. But much can be learned by combining observations over a broad range in the electromagnetic spectrum. So, the Global Telescope Network has been assembled to make observations in the optical range to complement the observations by space-borne observatories. Members can participate in a number of activities, including gamma-ray burst photometry analysis, surveillance data analysis, and galaxy monitoring, and by donating telescope time. The Global Telescope Network in turn provides involvement for students, teachers, and amateur astronomers in cutting-edge astronomical research. It also offers mentoring in research practices, telescope use, data analysis, and educational resources.
