How many things can you see in the night sky? A lot! On a clear night you can see the moon, some planets, and thousands of sparking stars.
You can see even more with a telescope. You might see that many stars look larger than others. You might see that some stars that look white are really red or blue. With bigger and bigger telescopes you can see more and more objects in the sky. And you can see those objects in more and more detail.
But scientists believe there are some things in the sky that we will never see. We won’t see them with the biggest telescope in the world, on the clearest night of the year.That’s because they’re invisible. They’re the mysterious dead stars called black holes.
You might find it hard to imagine that stars die. After all, our sun is a star. Year after year we see it up in the sky, burning brightly and giving us heat and light. The Sun certainly doesn’t seem to be getting old or weak. But stars do burn out and die after billions of years.
As a star’s gases burn, they give off light and heat. But when the gases run out, the star stops burning and begins to die.
So next time you look up at the night sky, remember: there’s more in the sky than we can see!

In the sunny night, look up at the clear night sky. You can probably see thousands of stars. The biggest thing you’ll see, of course, is the moon. For thousands of years, people have wondered about this big thing in the sky.
Earth’s moon is a satellite. A satellite is a body that orbits(环绕轨道运行)a planet. All moons are satellites, and many planets have them. Some have many moons. Earth, of course, only has one. It’s a special moon, though. It’s the fifth largest moon in the solar system!
In fact, the moon is much smaller than the sun. But it’s much closer to Earth, so it looks as big as the sun. The moon is so close that you can see its dark and light spots(斑点)without a telescope. Men flew and landed on the moon’s surface many times by spacecrafts in the 1960s and 1970s. Neil Armstrong was the first human to step on the moon. He walked on the moon on July 20th, 1969. The flights to the moon have helped us learn much about it. Astronauts even brought rocks home with them!
There’s still a lot to learn about the moon. Now people still can’t live on the moon because it does not have oxygen or water like the Earth. But I’m sure that humans can live there one day in the future.
