What is a Nebula?

• A small, rocky body orbiting the sun

• A device used to observe distant heavenly bodies

• An enormous cloud of dust and gas in space

• A moon, planet, or machine that orbits a planet or star

What is the difference between a Refractor Telescope and a Reflector Telescope?

• A Refractor Telescope uses mirrors, while a Reflector Telescope uses lenses

• A Refractor Telescope uses lenses to bend light, while a Reflector Telescope uses mirrors to magnify objects

• A Refractor Telescope magnifies distant objects, while a Reflector Telescope bends light

• A Refractor Telescope and a Reflector Telescope are the same

What is the purpose of a Spectroscope?

• To collect and focus radio waves

• To collect light from distant stars and separate it into bands

• To bend and focus light rays to produce images of objects in space

• To launch into orbits for observing distant heavenly bodies
