     Not long ago, an airplane was flying over New Zealand. There was a television camera crew on board.

Suddenly, out in the night sky, a bright sphere came into view. Everyone on board saw it and everyone

thought, "UFO"-Unidentified Flying Object (不明飞行物). The camera crew went into action and started

filming. That week people all over the world saw the film of this mysterious light on their television screens.

What was it? Was it a spaceship full of visitors from another planet? The captain of the aeroplane and the

film crew believed it was. Other observers had many different explanation. Some said it was Venus. Others

said it was just a trick of light.

     An air traffic controller (机场导航员) also saw it on his radar screen. He thought that a flock of birds

was causing dots on his radar screen when the "UFO" appeared.

     Most astronomers now believe that what these people saw was almost certainly the planet Venus. At that

time of year it is very bright and easy to see. And from a more aeroplane it can appear to be moving fast. So

far there is no proof that UFOs or spaceships from other planets do exist. These years investigators of UFOs

here investigated thousands of sightings-or occasions when people said they saw a UFO. Ninety percent of

these turned out to have a simple explanation.

     However, it's a good idea to keep an open mind. Scientists in some countries are trying to persuade their

governments to help them study UFOs. And they are planning to co-operate internationally on reporting and

investigating sightings of UFOs.

     After all, it is quite possible that there is life out there in the universe. And if something is alive, it is quite

possible that it will come to visit us.
