JAMES:
THE BIG DIPPER IS IN A GREAT LOCATION FOR

VIEWING ALL MONTH.

DEAN:
THAT'S RIGHT JAMES, AND THE LIGHT FROM SEVERAL

OF THE SEVEN BIG DIPPER STARS TAKE A LIFETIME
TO GET HERE.

JAMES:
WHEN WE LOOK AT THE BIG DIPPER, WERE ACTUALLY

LOOKING BACK IN TIME.

IT TAKES YEARS FOR STARLIGHT TO REACH EARTH.

IN FACT, THE LIGHT WE SEE FROM THE CLOSEST
STAR IN THE BIG DIPPER, MEGREZ, LEFT 58 YEARS

AGO IN 1960.

DEAN:
ALIOTH AND PHECDA ARE BOTH ABOUT 83 LIGHT

YEARS AWAY SO THEY LEFT THOSE STARS BACK IN
1935.

JAMES:
MIZAR IS 78 LIGHT YEARS AWAY, AND THE LIGHT

WE SEE FROM ALKAID BEGAN ITS JOURNEY 104 YEARS
AGO.

DEAN:
THE LAST TWO STARS ARE DUBHE AND MERAK.

MERAK IS 80 LIGHT YEARS FROM EARTH, BUT DUBHE
IS A WHOPPING 123 LIGHT YEARS AWAY.

LOOKING AT THE BIG DIPPER AND THAT OLD, OLD
STARLIGHT CAN REALLY MAKE YOU FEEL LIKE A

TIME TRAVELER.

BOTH:
KEEP LOOKING UP!
