WHAT IS ASTRONOMY?
WHAT IS ASTRONOMY?
IT IS THE SCIENCE THAT STUDIES
OBJECTS IN SPACE (OFF PLANET
EARTH).
MANNED AND UNMANNED SPACE PROBES
CAN BE USED TO STUDY OBJECTS CLOSE
TO EARTH, BUT WHAT IS THE MOST
IMPORTANT TOOL THAT SCIENTISTS
CAN USE TO STUDY DISTANT OBJECTS?

TELESCOPES (LIGHT)
WHAT ARE THREE ADVANTAGES THAT A
TELESCOPE WOULD HAVE OVER USING
THE HUMAN EYE?
WHAT ARE THREE ADVANTAGES THAT A
TELESCOPE WOULD HAVE OVER USING
THE HUMAN EYE?
1) A TELESCOPE CAN GATHER MORE
LIGHT. THIS WOULD HELP IN SEEING
FAINT OBJECTS.
2) A TELESCOPE CAN MAGNIFY DISTANT
OBJECTS.
3) TELESCOPES CAN USE LIGHT AT
WAVELENGTHS OTHER THAN VISIBLE
LIGHT.
WHAT IS LIGHT?
WHAT IS LIGHT?
IT IS A FORM OF ENERGY THAT HAS BOTH

NAME THREE THINGS THAT
ASTRONOMERS CAN USE LIGHT
TO MEASURE.

ASTRONOMERS CAN USE LIGHT
TO MEASURE.
1. SURFACE TEMPERATURE OF
STARS
2. ELEMENTS PRESENT IN STARS
AND NEBULAES
3. SPEED AT WHICH OBJECTS ARE

5. AGE OF STARS
HOW CAN ASTRONOMERS USE TELESCOPES
TO COLLECT MORE LIGHT?
1. USE LARGER MIRRORS
2. MAKE TIME EXPOSURES
