Video Summary

The GTC or Gran Telescopio Canarias is a massive 10.4 meter telescope that is able to study the slightest light emissions from distant objects in space. The construction of the GTC began in March 2009, as soon as the development of its control systems, telescope optics and science instrument OSIRIS (Optical System for Imaging and low Resolution Integrated Spectroscopy) were complete. So far the GTC has been able to confirm the composition of atmospheres of multiple exoplanets, the dynamics of the stars around the central black hole of our galaxy, and the nature of brown dwarf stars.
