Some space objects are visible to the
human eye.
• Gravity causes objects in space to be grouped together
in different ways.
• Stars form patterns in the sky.
• The sky seems to turn as Earth rotates.

Telescopes allow us to study space
from Earth.
Each form of electromagnetic radiation provides
different information about objects in space.
Astronomers use different types of telescopes to gather
visible light and other forms of radiation.

CHAPTER HOME
Spacecraft help us explore beyond Earth.
Astronauts can explore space near Earth. Spacecraft
without crews carry instruments to other worlds. A flyby
mission usually provides data from several bodies in
space. Orbiters, landers, and probes gather data from
one planet or body.

Space exploration benefits society.
Space exploration has taught us about Earth’s
development. It has also provided technology that has
important uses on Earth.
This boy communicates using technology developed
by designers at NASA.
