Since 1990, the Hubble Space Telescope has been orbiting Earth and sending back images of space for astronomers to view and interpret. What benefit is there to a telescope that orbits Earth?
Views from outer space telescopes are clearer that those from Earth-based telescopes.
Earth-based telescopes have a greater range of light detection.
Human error is reduced by the use of the Hubble telescope.
The Hubble telescope is used to examine events that cannot be explained.
Which of these is an unpiloted spacecraft designed to gather information while orbiting planets other that Earth?
space probes
space shuttle
space station
space telescope
A cluster of stars, dust, gas and matter is a
galxay
planetary system
universe

a satellite
a space probe
a telescope
a spectroscope
Which space tool allows us to determine which elements are present in a star or in the atmosphere of other planets?
a satellite
a space probe
a telescope
a spectroscope
Which of these is NOT a main type of galaxy?
Elliptical

Using the Doppler Effect scientists have determined that the universe is expanding. They know this because ___ .
most of the galaxies we see have a blue tint to their color
most of the galaxies we see have a red tint to their color
most of the galaxies we see have a dark color
most of the galaxies we see are too dim to see
TRUE/FALSE: The Doppler Effect tells us that galaxies that are moving away from us have a red tint to their color because the light waves are being stretched out, thus increasing the wavelength and lowering the frequency.
True
False
TRUE/FALSE: Astronomers use a light year to measure space because the distances in space are too large to use ordinary measurements such as miles and kilometers.
True
False
