About

The GTN is a network of small telescopes around the world. Members include students, educators and amateur and professional astronomers. The purpose of the GTN is to support the science of NASA and ESA high energy astrophysics missions, including XMM-Newton, Swift and Fermi. These missions are designed to study astronomical objects through their emission of x-rays and gamma rays. However, much can be learned by combining observations over a broad range in the electromagnetic spectrum. The GTN has been assembled to make observations in the optical that will compliment the observations done at higher energies by space-borne observatories.
