TRACE HERE -- HAPPY GLOBAL ASTRONOMY MONTH!
APRIL IS A GREAT TIME TO SEE EARTHSHINE.
YOU ALREADY KNOW THE MOON DOESN T SHINE; IT S RE-FLECTING LIGHT FROM THE SUN, BUT WHEN THINGS LINE UP JUST RIGHT, REFLECTED LIGHT FROM EARTH ILLUMI-NATES THE MOON.
IT S CALLED EARTHSHINE, AND IT MAKES THE MOON LOOK LIKE A BEAUTIFUL ORB SUSPEND-ED IN THE SKY!
EARLY IN THE WEEK EARTHSHINE WILL BE VISIBLE BEFORE SUNRISE DURING A CONJUNCTION WITH VENUS, MARS AND SATURN I MENTIONED IT LAST WEEK.
THEN, BY APRIL 4 AND 5, EARTHSHINE WILL BE ON FULL DISPLAY JUST AFTER SUNSET!
ALBEDO DESCRIBES THE AMOUNT OF LIGHT REFLECTED BY CELESTIAL BODIES.
MORNING-STAR VENUS REFLECTS 75% OF THE LIGHT THAT HITS ITS TOXIC CLOUDS; THE MOON?
ONLY 12%!
EARTH S LANDSCAPE PRODUCES DIFFERENT ALBEDOS.
SNOW S ALBEDO IS 84% WHILE FORESTS ARE ONLY 14.
ON AVERAGE, EARTH ALBEDO IS ABOUT 30.
GO SEE THE MOON BATHED IN EARTHLIGHT AND KEEP LOOKIN UP!
