• Scientists have reviewed old theories and studied the life cycles of stars.

• Scientists have gained direct observations through new technologies.

• Scientist have kept more accurate records of the revolution of other planets.

• Scientist have studied the more distant galaxies.

Multiple Choice

Astronomers and biologists study different areas of science. Many astronomers observe far distant objects in the sky. Many biologists study extremely small objects. What do these astronomers and biologists have MOST in common?

• They bother examine the history of life on Earth.

• They both make discoveries using optical devices.

• They both study how organisms change over time.

• They bother search for evidence about the origins of the universe.

Multiple Choice

What advantage is gained by using radio telescopes as opposed to optical telescopes?

• viewed images are clearer

• operation is less complex

• ability to see through clouds and dust

• ability to take up less space

Multiple Choice

Since 1990, the Hubble Space Telescope has been orbiting Earth and sending back images of space for astronomers to view and interpret. What benefit is there to a telescope that orbits Earth?

• Views from outer space telescopes are clearer that those from Earth-based telescopes.

• Earth-based telescopes have a greater range of light detection.

• Human error is reduced by the use of the Hubble telescope.

• The Hubble telescope is used to examine events that cannot be explained.

Multiple Choice

This instruments is used by astronomers to collect incoming microwaves, what is the instrument used?

• space probe

• solar collector

• radio telescope

• orbiting satellite

Multiple Choice

The Hubble Space Telescope is a telescope that NASA launched into space in 1990. Scientists MOST likely prefer to use the Hubble Space Telescope instead of a land-based telescope because it provides better accuracy.

• investigating faraway galaxies.

• investigating the size of Venus.

• Predicting the phases of the moon.
