Telescopes

Telescopes

100

These were the first telescopes developed and use curved lenses to magnify images.

Refracting Telescopes

200

These telescopes use curved mirrors to enlarge images

reflecting telescopes

300

These telescopes use a combination of lenses and mirrors to collect light.

catadioptric telescopes

400

These telescopes look like satellite dishes and can only see what is directly overhead

radio telescopes

500

This person greatly improved the design of reflecting telescopes

Isaac Newton

Space

100

This is a band of stars that span across our galaxy

Milky Way

200

These created the craters on the Moon

Meteors

300

A light year is a measure of this

Distance

400

A light year is about this far

9.5 trillion kilometers

500

Light from the most distant objects in the universe arrives on Earth as this

Radio waves

Early Astronomy

100

This is the meaning of the term "planet"

Wanderer

200

These are what the Greeks recognized as patterns of stars in the sky

Constellations

300

This is the type of telescope Galileo used to make his observations of the night sky.

Refracting telescope

400

Galileo agreed with the ideas of this person which got him in trouble with the Roman Catholic Church.

Nikolaus Copernicus

500

During Galileo's time most people believed this about the Sun and planets

They orbited the Earth.

Electromagnetic Waves

100

This is the number of waves passing a given point per second

Frequency

200

This is the distance between two adjacent wave oscillations.

Wavelength

300

This is a range of electromagnetic wavelengths  between 400 and 700 nanometers.

Visible light

400

This is the type of Electromagnetic wave has the shortest wavelength and the greatest amount of energy

Gamma Rays

500

Very hot stars release energy in the form

Ultraviolet light

New tech

100

Newton improved his telescope by adding and extra mirror near the eyepiece at this angle

45^o

200

These two probes were sent to our outer solar system

Voyager and Pioneer

300

These telescopes are able to avoid light interferene from the Earths' atmosphere

Space telescopes

400

This telescope was at first unsuccessful and had to be repaired in space by a NASA shuttle mission

Hubble Telescope

500

The James Webb Space telescope detects this type of electromagnetic wave

Near infrared and mid-infrared wavelenghts.
