HI STARFAM!
WISH GALILEO A HAPPY BIRTHDAY.
457 YEARS AGO ON FEBRUARY 15, FAMOUS ITALIAN AS-TRONOMER GALILEO GALILEI WAS BORN.
THIS WEEK IS THE SNOW MOON; THE FULL MOON OF FEB-RUARY, SO GET OUT AND WATCH THE SKIES LIKE OUR FA-VORITE ASTRONOMER.
GRAB SOME BINOCULARS AND HEAD OUTSIDE TO LOOK AT THE MOON.
IN THE 16TH CENTURY, IT WAS THOUGHT THE MOON WAS A PERFECT SPHERE AND WHEN THE MOON IS FULL IT CAN LOOK PRETTY FLAT.
BUT, IF YOU LOOK AT IT DAY AFTER DAY YOU LL NOTICE THE DARKNESS MOVING ACROSS ITS FACE.
IF THE MOON WAS SMOOTH, THE SHADOW WOULD BE SMOOTH TOO, BUT THROUGH BINOCULARS, YOU CAN RE-ALLY SEE THAT THE EDGE OF THAT SHADOW IS CRAGGLY!
MEANING THE MOON HAS MOUNTAINS!
THIS IS HOW GALILEO REALIZED THE MOON HAD CHAINS OF MOUNTAINS AND DEPTHS OF VALLEYS JUST LIKE FEATURES HERE ON EARTH.
GET OUT THERE AND GET A LITTLE GALILEO EXCITEMENT!
KEEP LOOKING UP.
