1. There is strong evidence that some bacteria can survive strong ultraviolet light from the sun and other space radiation.

2. One possibility is that ultraviolet light damages the retina, just as it damages the skin over time.

3. This allows the sensor to capture a wide spectrum of electromagnetic radiation, including ultraviolet light.

4. Through optical filters, samples were also subjected to ultraviolet radiation as if on Mars and others to lower radiation.

5. Ultimately, knowing that many animals have ultraviolet vision could provide a deeper understanding of why they behave the way they do.
