Science Center Hosting SkyWatch Party For Super Blood Wolf Moon Lunar Eclipse


HAVE YOU HEARD THERE WILL SOON BE A SUPER BLOOD, WOLF MOON, A TOTAL LUNAR ECLIPSE. WHEN IS IT? THE ANSWER CAN BE COMPLICATED. DON’T WORRY, WE HAVE AN EXPERT THIS MORNING TO EXPLAIN. OKAY. WHAT ARE WE TALKING ABOUT? THERE’S A LOT OF STUFF GOING ON THERE. LET’S TAKE IT APART. A SUPER MOON IS JUST, AND WE HAVE A VERY TECHNICAL MODEL. THIS IS THE EARTH AND THE MOON. A SUPER MOON IS WHEN YOU HAVE A FULL MOON, WHEN THE MOON IS IN THE POINT IN ITS ORBIT WHEN IT’S CLOSEST. AS IT MOVES AROUND THE EARTH, THE DISTANCE CHANGES A LITTLE’S IF THAT HAPPENS TO BE FULL, WHEN IT’S CLOSEST WE CALL IT SUPER AND THAT’S WHEN IT LOOKS THE BIGGEST. THE DIFFERENCE IS RELATIVELY SMALL, ABOUT 40% DIFFERENCE. BUT THE OTHER THING I WANT TO DEMONSTRATE IS THE DISTANCE BETWEEN THE TWO. THEY ARE A LOT FURTHER APART. THIS IS AN 8 INCH WIDE EARTH. THIS IS A 2 INCH WIDE MOON. HOW FAR APART DO YOU THINK THEY WOULD BE IN SPACE? MAKE AN ACTUAL SCALE. NOT THIS CLOSE. I WILL SAY ABOUT IT RIGHT HERE. THAT’S NOT A BAD GUESS, BUT YOU HAVE TO GO A LITTLE BIT FURTHER. FURTHER? LET’S TRY THIS. I WILL STEP AWAY A LITTLE BIT. A LITTLE BIT FURTHER. MAY BE FOR MORE STEPS. ABOUT THERE. RIGHT ABOUT THERE. ON THIS SCALE, THIS IS AN 8 INCH WIDE MODEL, YOU HAVE TO BE ABOUT 20 FEET AWAY. THAT IS THE DIFFERENCE BETWEEN THE EARTH AND THE MOON. WHAT YOU THINK IS AMAZING IS THAT IS COVERED. WE THINK VALVE ASTRONAUTS GOING OUT TO THE MOON, THAT IS IMPRESSIVE. WE ARE COMING UP ON 50 YEARS. AT THE ASTRONAUTS ON SPACE STATION ARE MUCH CLOSER TO HOME. THE STATION OVER IT’S ABOUT THIS FAR AWAY. REALLY? YEAH, IT’S JUST A FRACTION OF AN INCH AWAY OFF THE SURFACE. I WILL COME BACK. WE UNDERSTAND THE SUPER MOON IS BECAUSE THE MOON IS FULL WHEN IT’S CLOSEST. THE WOLF MOON, JUST FROM THE MOON IN JANUARY. IT’S A FULL MOON OF EVERY MONTH WHICH HAS A NICKNAME. IT’S BEEN USED IN FARMER’S ALMANACS FOR CENTURIES. THE JERRY FULL MOON IS CALLED THE WOLF MOON. IS ASSOCIATED WITH THE WALLS HOWLING AT THE MOON IN THE MIDDLE OF WINTER. AND THEN WITH THE BLOOD MOON AND THE TOTAL LUNAR ECLIPSE WHICH ARE THE SAME THING. AND I CAN DEMONSTRATE THAT BUT WE WILL NEED TO BRING THE LIGHTS DOWN BECAUSE WE HAVE A MODEL OF THE SUN SET UP AND I WOULD LIKE TO SHOW YOU POTENTIALLY WHAT’S GOING ON HERE. IMAGINE THE EARTH IN SPACE CASTING A SHADOW. THANKFULLY THIS WALL CAN DEMONSTRATE THAT SHADOW. AS THE EARTH IS IN SPACE, THE MOON ORBITS AND IT WILL OFTEN COME JUST ABOVE THE EARTHS SHADOW OR JUST BELOW IT BECAUSE THE MOON HAS A BIT OF A TILT IN ITS ORBIT. KEEP IN MIND, IN REAL LIFE IT IS ABOUT 20 FEET APART, REALLY FAR APART. IF WE ARE REALLY LUCKY, THE MOON WILL HIT RIGHT INTO THE EARTH SHADOW. FOR ABOUT AN HOUR, WE HAVE ONE OF THESE COMING UP ON SUNDAY. FOR AN HOUR, THE MOON WILL BE IN THE SHADOW OF THE EARTH. THAT IS THE LUNAR ECLIPSE? THAT’S RIGHT, THAT IS EXACTLY WHAT THEY LUNAR ECLIPSES. WHEN THAT HAPPENS, YOU WOULD EXPECT IT TO BE BLACK, BUT HERE , THE EARTH HAS ATMOSPHERE AROUND IT. THE AIR ACTS LIKE A LENS AND IT BENDS LIGHT SO THERE’S ACTUALLY LIKE THAT MAKES IT AROUND THE EARTH AND THAT LIGHT IS FILTERED. WE SEE ONLY CERTAIN COLORS, TYPICALLY. LET’S STOP, THE ATMOSPHERE AROUND THE EARTH, THAT IS THE LENS THAT BENDS THE LIGHT. THAT IS FUNCTIONALLY A LENS, A REFRACTS LIGHT AROUND THE EARTH AND ITS GATHERS THAT LIGHT PREFERENTIALLY BY COLOR. THE COLOR THAT MAKES IT TO THE MOON WILL BE THE COLOR OF A SUNSET. WHEN THE SUN IS SETTING, USE THAT BEAUTIFUL DEEP RED? IF YOU ARE STANDING ON THE MOON DURING A LUNAR ECLIPSE, YOU WOULD LOOK AT THE EARTH AND SEE EVERY SUNSET AND SUNRISE AT THE SAME TIME. THAT WILL COLOR THE MOON A DEEP BLOOD RED COLOR. IT WILL BE THAT BLOOD MOON COLOR FOR ABOUT AN HOUR STARTING AT 11:40 PM ON SUNDAY. 11:40 PM ON SUNDAY NIGHT? THAT’S RIGHT. HOW OFTEN DOES THAT HAPPEN, RALPH? WE WILL HAVE ANOTHER ONE IN PITTSBURGH UNTIL 2022. OKAY. IT’S RARE BUT NOT AS RARE AS A SOLAR ECLIPSE. NOW, A SOLAR ECLIPSE IS WHEN THE EARTH AND MOON ARE LINED UP THE OTHER WAY AROUND AND THE MOON IS CASTING ITS SHADOW ON US. THE MOON IS MUCH SMALLER. IT IS A VERY SMALL SHADOW. FAMOUSLY WE HAD A ECLIPSE IN AUGUST 2017 AND THE SHADOW, THE DARKEST PART THAT HIT THE EARTH AT THAT TIME WAS ONLY ABOUT 30 MILES WIDE. WHERE IS THE EARTHS SHADOW COVERS A WHOLE MOON. THE MOON SHADOW JUST CASTS A LITTLE THOUGHT ON THE EARTH BECAUSE THE MOON IS MUCH SMALLER. KEEP IN MIND THE DISTANCE IS TREMENDOUS. IF WE HAD THE SUN ENTER THIS IT WOULD BE FURTHER. ON THE SAME SCALE, THE SON WOULD BE OVER 70 FEET WIDE. IT WOULD BE AS WHITE AS THE STUDIO. IT WOULD BE A MILE AND A HALF AWAY. WOULD BE SO FAR AWAY THAT YOU COULD IMAGINE A 70 FOOTBALL LOOKING LIKE THE SUN IN THE SKY. YOU GUYS HAVE SOMETHING ON SUNDAY. YES, WE HAVE A SPECIAL EVENT, A SPECIAL EDITION OF OUR SKY WATCH WHICH IS A ASTRONOMY PROGRAM. WE WILL BE RUNNING OUR PLANETARIUM WHERE WE CAN SEE THE STARS, PLANETS CONSTELLATIONS AND GALAXIES. WE WILL HAVE A EVENT SPACE IN PPG SCIENCE PAVILION OPEN AND WILL HAVE TELESCOPES SET UP THERE. WILL GO UNTIL 1 AM OBSERVING THE MOON AND EVEN IF THE WEATHER IS NOT GREAT, WE WILL BE LIVE STREAMING AT AND WILL HAVE MULTIPLE ASTRONOMICAL DEMONSTRATIONS. WILL HAVE STAFF MEMBERS ON HAND AND TICKETS HAVE BEEN GOING VERTICALLY FOR THIS EVENT. TICKETS ARE TWO DOLLARS? THEY ARE FOUR DOLLARS OR TWO DOLLARS FOR MEMBERS. AND WE ACTUALLY MAY BE SELLING OUT. IF YOU’RE INTERESTED, DEATHLY PICK UP YOUR TICKETS SOONER RATHER THAN LATER. THANK YOU SO MUCH FOR THE DEMONSTRATION. THIS IS FASCINATING. THANK YOU TO CARNEGIE SCIENCE FOR TODAY’S LESSON.
