B. black holes. C. nebulae. D. planets. 4. A black hole is an invisible, highly dense celestial body with gravity strong enough to keep light from escaping. It is called a black hole because A. black holes were named after their discoverer, Richard Black. B. it is a big, dark hole in space. C. it always appears dark, since no light can leave it.

Stars are classified according to characteristics that can be observed from Earth. Which of the following is not a characteristic for classifying stars? A. the star’s luminosity, or brightness B. the star’s color C. the star’s size D. All of these are possible characteristics. 7. Although they did not have telescopes, ancient people studied space.

The universe is made up of billions of galaxies that seem to be moving away from each other. This is evidence for which theory? A. the theory that the universe is expanding in size B. the theory that all matter repels (pushes away) other matter C. the theory that the universe is shrinking D. the theory that the universe has a fixed size 9.

It has the same brightness throughout. D. It’s not bright at all. 10. Galaxies are made up of billions of stars, all giving off light, but many galaxies can only be seen with powerful telescopes. What is a possible reason for this? A. They are so far away from Earth that their light is very faint. B. They are made up of only small stars. C. They are in motion, so they are harder to see. D.
