The planet GU Piscium b and its star GU Piscium composed of visible and infrared images from the Gemini South telescope and an infrared image from the CFHT. Because infrared light is invisible to the naked eye, astronomers use a colour code in which infrared light is represented by the colour red. GU Piscium b is brighter in infrared than in other filters, which is why it appears red in this image.
