Space Based Astronomy and Telescopes

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

Space observatories are used to:

• Collect data
• Take pictures
• All answers
• Transmit information

When did the Hubble Space Telescope start ?

• 1840

• 1995

• 1990

• 1976

Why must Ultra-Violet observing be done in space?

• The ozone blocks most of the UV rays in the surface.

• t’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

What is a disadvantage of using a space telescope?

• The images are clearer due to the absence of the Earth's atmosphere

• All wavelengths can be observed in space.

• Astronomer's can "see" through clouds of gas and dust

• It is challenging to repair a space telescope

This telescope will orbit the sun at a distance of 1 million miles from Earth to gather infrared waves.
