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
Telescopes
• 2 Types of Optical • Refracting: uses convex lenses
Telescopes:
• Reflecting :uses mirrors
• Both collect visible light & use
their particular tools to focus the
light to produce larger, brighter
images of distant space objects
• Radio Telescopes • receive radio waves emitted
from objects in space, including
waves from very distant stars &
galaxies used anytime, in any
weather
Other telescopes
• How are other
telescopes
different from
optical & radio
telescopes?
• other telescopes
“read” infrared or xray signals
• they have to be
placed where Earth’s
atmosphere doesn’t
block or absorb the
signals
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
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
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
