The Global Telescope Network (GTN) is part of NASA’s Universe of Learning. Our goal is to advance STEM learning and literacy by using Internet-controllable telescopes to engage learners in authentic research experiences. The GTN is developed and maintained by scientists, engineers, and educators at Sonoma State University (SSU), in partnership with remote telescope networks around the world. The GTN provides opportunities for participants to learn astrophysics content and skills on their own timelines and in their own environments. While the GTN partners with other remote telescopes and telescope networks such as Skynet, it also has its own 14-inch Schmidt-Cassegrain robotic telescope, nicknamed GORT (Gamma-ray Optical Robotic Telescope), which has been in operation since 2004. GORT can be remotely operated, and has a selection of filters that provide images in different visible wavelength bands.
