Jupiter was at "opposition" yesterday, which means that it's still almost at opposition today. "Opposition" means that it's on exactly the opposite side of the Earth from the Sun. The picture to the right shows diagrammatically the layout of the Solar System when Jupiter is at opposition. This means a few things. First, we're closer to Jupiter than we are at any other time. This means that Jupiter is both brighter and, if you have a telescope, a bit bigger than it usually is. Second, it means that Jupiter is as high in the sky as it will get right at local midnight (which is generally some time close to local 12:00AM).
If Jupiter is opposite the Sun, that means it will be rising in the East right as the Sun is setting in the West. Look for a very bright "star" in the Eastern sky a bit after Sunset. It's not a UFO; it's the planet Jupiter. if you're up at midnight, the very bright "star" that is nearly overhead is Jupiter.
You can see the four Galilean moons of Jupiter with binoculars... if you can hold them still enough! Get a pair of 7x35, 7x50, or 10x50 binoculars, and point them at Jupiter. Try leaning on something, or laying down on the ground, to hold your binoculars still enough. If you can, you will see up to four small specs of light lined up on one or both sides of Jupiter. Sometimes stars will happen to be there, but some of those specs of light are, indeed, the moons of Jupiter. Watch them from one day to the next, and you'll see that they change positions with each other.
