People develop and use technology to explore and study space.
Kept apart by the planets between them
Held together by their own gravity
That form a pattern in the sky
Form a pattern when orbiting Polaris
Are very lose to one another
Seem grouped together when viewed from Earth
Earth's rotation
The rotation of Polaris
The orbit of Earth around the constellation
Invisible to the human eye
Visible to the human eye
Evergy that travels through space as waves
The range of all types of electromagnetic radiation
The range of colors of light that occurs when white light passes through a colored filter
The range of colors of light that occurs when white light passes through a prism
It is not affected by Earth's atmosphere
It is closer to the objects it is imaging
It can collect radio waves and visible light
