Yes, water can stay liquid below zero degrees Celsius.

This can happen because the phase of water (gas, liquid or solid) depends on many things such as pressure and temperature. For liquids like water, the freezing point of water drops as you apply pressure.

This can also happen by additives, like salt, which can lower the freezing point of water. For example, the more salt you add to water, the lower the freezing point will be. This will continue till you reach the saturation point of water, where the water will no longer absorb the salt and the effects no longer stack.

All four of the gas giant planets in our solar system – Jupiter, Saturn, Uranus, and Neptune – are known to have rings.

These rings are created by asteroids and small moons that were broken up by gravity and other forces that got into orbit around the planet.
