About Hubble. The Hubble Space Telescope is a collaboration between ESA and NASA. It's a long-term, space-based observatory. The observations are carried out in visible, infrared and ultraviolet light.utting a telescope in space is one way of evading this problem. As well as collecting visible light from its orbit high above the atmosphere, the Hubble Space Telescope also observes the infrared and ultraviolet wavelengths that are completely filtered out by the atmosphere.
