• NASA trains astronauts in many cities across Florida.

The Hubble Telescope and the James Webb Telescope are both powerful tools for exploring space. They have taken pictures of stars, galaxies, and other huge objects. How are these two telescopes that scientists use to study space?

• The two telescopes are unusually large and heavy.

• The two telescopes use mirrors instead of lenses.

• The two telescopes are housed on tall, remote mountains.

• The two telescopes are in space, where they orbit around Earth.

Throughout the night, many stars appear to move in a circular path across the sky. The center of the circle is Polaris, also called the North Star. What causes this apparent motion of the stars?

• The revolution of the stars around Earth causes this apparent motion.

• The movements of the Sun and Moon through space causes this apparent motion.

• The rotation of Earth on its axis causes this apparent motion.

• The movement of clouds and other objects close to Earth’s surface causes this apparent motion.
