Answer
The moons of Jupiter are visible from Earth due to the reflection of sunlight off their surfaces. Though these moons do not have any light of their own, the light from the Sun reaches their surfaces, and upon reflection, some of this light reaches us, making the moons of Jupiter visible to us.
Explanation
## Step1: The moons of Jupiter, just like the other celestial bodies like planets that do not have a light of their own, are visible from the Earth due to reflection of light from the Sun falling on them. ## Step2: When sunlight hits the surface of these moons, they reflect this light. Therefore, although these moons do not produce any source of light of their own, the light source that comes from the Sun is reflected off of their surfaces. ## Step3: Thus, we are able to see the Jovian moons. We see them not because they have any light of their own, but the light they reflect from the Sun, reaches our eyes.
