Can moons have moons?

Yes, in theory, moons can have moons. The region of space around a satellite where a sub-satellite can exist is called the Hill sphere. Outside the Hill sphere, a sub-satellite would be lost from its orbit about the satellite. An easy example is the Sun-Earth-Moon system.

A single crescent moon is a familiar sight in Earth's sky, but with Saturn's many moons, you can see three or even more.

A big bang to be exact! Billions of years ago, all matter of the universe was compressed into one tiny point until it finally exploded around 12-14 billion years ago. This explosion is what scientists call the Big Bang. During this time, humongous masses of dust and gas spewed throughout space.

How long will the Earth last?

The upshot: Earth has at least 1.5 billion years left to support life, the researchers report this month in Geophysical Research Letters. If humans last that long, Earth would be generally uncomfortable for them, but livable in some areas just below the polar regions, Wolf suggests.
