JAMES: THIS WEEK, WE'RE GOING TO TALK ABOUT
ONE OF THE CONSTELLATIONS THAT MAKES UP THE

SUMMER TRIANGLE.

DEAN: THAT'S RIGHT, JAMES.

WE'RE GOING TO GIVE YOU A GUIDED TOUR OF THE
CONSTELLATION LYRA THE HARP.

LET'S SHOW YOU!

JAMES: OK, WE'VE GOT OUR SKIES SET UP FOR
ANY NIGHT THIS WEEK, AT ABOUT 10 PM.

IF YOU LOOK TOWARD THE EAST, YOU WILL SEE
THE STARS OF LYRA AT THE TOP OF THE SUMMER

TRIANGLE.

DEAN: LYRA IS OFTEN SAID TO BE THE SMALL HARP
THAT BELONGED TO APOLLO AND WAS LATER GIVEN

TO ORPHEUS.

ORPHEUS WAS SO SKILLED AT PLAYING THE HARP,
THAT THE MUSIC WAS SAID TO CHARM ANYONE WHO

HEARD IT.

JAMES: THE BRIGHTEST STAR IN LYRA IS VEGA;
A MAIN SEQUENCE STAR, 25 LIGHT YEARS FROM

EARTH.

TRAVELING COUNTER-CLOCKWISE FROM VEGA, WE
HAVE FOUR STARS FORMING A PARALLELOGRAM, THEY

ARE ZETA LYRAE, DELTA LYRAE AND THE TWO ON
THE FAR END ARE, SULAFAT AND SHELIAK.

BOTH: KEEP LOOKING UP!
