3. Use of Space Tools How do astronomers use space tools & technology to learn about space? to make observations to collect data about objects in & outside of the solar system to analyze & interpret the data

4. Telescopes 2 Types of Optical Telescopes: Radio Telescopes Refracting: uses convex lenses Reflecting :uses mirrors Both collect visible light & use their particular tools to focus the light to produce larger, brighter images of distant space objects receive radio waves emitted from objects in space, including waves from very distant stars & galaxies used anytime, in any weather

5. Other telescopes How are other telescopes different from optical & radio telescopes? other telescopes “read” infrared or x- ray signals they have to be placed where Earth’s atmosphere doesn’t block or absorb the signals

6. Satellites placed in orbit around Earth have special instruments & telescopes that collect information from space data is sent back to Earth where it is interpreted data is not hampered (bothered) by Earth’s atmosphere

7. Space Probes travel out of Earth’s orbit to explore places that would be too dangerous for astronomers contain instruments to collect data the instruments a probe contains depends on the mission

8. Spectroscopes collect light from distant stars separates the light into bands of different colors astronomers study the bands to identify the elements of a star
