Star Gazers

THIS WEEK CEPHEUS IS GOING TO HELP# US SEE THE UNIVERSE IN A NEW WAY!

HIT THE DARKNESS AROUND MIDNIGHT AND LOOK NORTH.

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.

ITS 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 STARS 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!
