The Space Quiz

A device that detects radio waves from objects in space is called a(n)

• radio telescope.
• reflecting telescope.
• refracting telescope.
• electromagnetic telescope.

Why do we use the entire electromagnetic spectrum to study space?

• Because the visible spectrum is such a small part of light we are missing out by not doing so.
• So we can determine the direction galaxies are moving
• So we can understand the nature of time.
• So we can see the composition of galaxies

Why must Ultra-Violet observing be done in space?

• The ozone blocks most of the UV rays in the surface.
• It’s hard to know exactly where the ozone hole will be to find UV images
• It’s hard to use UV telescopes and radio telescopes together on the surface.
• It’s hard to use UV X-Ray telescopes and radio telescopes together on the surface

Why is the Hubble telescope located in space?

• So it can be closer to the stars it magnifies
• They have very large optical lenses
• So its images arent distorted by Earth's atmosphere 
• So it can be operated by astronauts 

If a star is being observed from Earth and it's light has shifted towards the blue side of the electromagnetic spectrum it would be...

• Moving towards the Earth
• Moving away from the Earth
• This is a trick question that cannot be answered
• It isn't a star, it is a very large blueberry.

If a star is being observed from Earth and it's light has shifted towards the red side of the electromagnetic spectrum it would be...

• Moving towards the Earth
• Moving away from the Earth
• This is a trick question that cannot be answered
• It isn't a star, it is a very large strawberry.

light emitted from an object moving towards you will have its wavelength shorted and will be considered

• red shiffted
• blue shiffted

Why are x-ray telescopes placed above Earth's atmosphere?

• to be closer to space

• the atmosphere absorbs most cosmic radiation from space

• they are too big to put on Earth

• X ray telescopes are to dangerous to operate on Earth

What's the difference between asteroids and comets?

• comets are made of rock and asteroids are made of dust and ice.
• Asteroids are made of rock and comets are made of dust and ice.
• Asteroids orbit the sun while comets orbit a planet.
• comets are larger than asteroids.

During which portion of the Earth's revolution around the Sun is the Northern Hemisphere tilted toward the Sun?

• Vernal equinox
• Summer solstice
• Winter solstice
• Autumnal equinox
