Question No - 1

Read the following passage and answer the questions. How many things can you see in the night sky? A lot! On a clear night you might see the moon, some planets, and thousands of sparkling stars. You can see even more with a telescope. You might see stars where before you only saw dark space. 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 I can see those objects in more and more details. **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 holes black called stars. 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, giving us heat and light. The Sun certainly doesn't seem to be getting old or weak. But stars do burnout and die after billions of years. ***As the gases of a star burn, they give off light and heat. But when the gas runs out the star stops burning and begins to die. As the star cools, the outer layers of the star pull in toward the center. **** The star squashes into a smaller and a smaller ball. If the star was very small to begin with, the star ends up as a cold, dark ball called a black dwarf. If the star was very big, it keeps squashing inward until it's packed together tighter than anything in the universe. *****Imagine if the earth were crushed until it was the size of the tiny marble. That' how this dead star, black hole, is packed. What pulls the star in toward its center with such power? It's the same force that pulls you down when you jump the force called gravity. A black hole is so tightly packed that its gravity sucks in everything.-even light. The light from a black hole can never come back to your eyes. That's why we see nothing but blackness. So the next time you stare up at the night sky, remember: there's more in the sky than meets the eye! Scattered in the silent darkness are black holes--the great mystery of the space. 1- What can bigger telescopes see? .......... .
