YOU'LL SEE THE FAMILIAR W-SHAPED# PATTERN OF CASSIOPEIA THE QUEEN.
DRAW A LINE FROM THE STARS ON THE# END OF THE W AND YOU'LL RUN SMACK DAB INTO CEPHEUS THE KING LOOKIN’ LIKE# A HOUSE ON ITS SIDE.
SEE-PHEUS .
GET IT?
CEPHEUS IS THE KING OF# ETHIOPIA, FATHER OF ANDROMEDA, AND HUSBAND OF CASSIOPEIA.
HIS# BRIGHTEST STAR IS ALDERAMIN, BUT HERE IS DELTA CEPHEII.
IT’S REALLY# IMPORTANT, BECAUSE IT CHANGES IN BRIGHTNESS.
SEE, IN NINETEEN TWELVE, ASTRONOMER HENRIETTA# LEAVITT DISCOVERED DELTA WAS CHANGING AT REGULAR INTERVALS.
ASTRONOMERS REALIZED THEY COULD USE# THIS REGULARITY TO DETERMINE THE STAR’S DISTANCE!
WHICH HELPED EDWIN HUBBLE REALIZE THE# ANDROMEDA NEBULA - WAS ACTUALLY A GALAXY!
NOW, CEPHEID VARIABLE STARS HELP US UNDERSTAND# DISTANCES ALL THROUGHOUT THE UNIVERSE.
KEEP LOOKING UP!
