About "Ask A Scientist!"
On September 17th, 1998 the Ithaca Journal ran its first "Ask A Scientist!" article in which Professor Neil Ashcroft , who was then the director of CCMR, answered the question "What is Jupiter made of?" Since then, we have received over 1,000 questions from students and adults from all over the world. Select questions are answered weekly and published in the Ithaca Journal and on our web site. "Ask A Scientist!" reaches more than 21,000 Central New York residents through the Ithaca Journal and countless others around the world throught the "Ask a Scientist!" web site.
Across disciplines and across the state, from Nobel Prize winning scientist David Lee to notable science education advocate Bill Nye, researchers and scientists have been called on to respond to these questions. For more than seven years, kids - and a few adults - have been submitting their queries to find out the answer to life's everyday questions.
Since the moon appears to follow nearly the same path as the sun in the sky, one might expect that the amount of time the moon spends above the horizon to vary as the moon orbits the earth, and indeed it does. As an example, think about the full moon. The moon is full when it is opposite the sun on the sky, so a full moon rises roughly at sunset, and sets at sunrise. Therefore, we only see full moons at night. On the summer solstice, the longest day of the year, when the sun spends the most time above the horizon, the full moon, in the night-time sky spends the least amount of time above the horizon. On the other hand, on the winter solstice, the shortest day of the year, when the sun spends the least time above the horizon, the full moon, again in the nighttime sky spends the most amount of time above the horizon. The time spent above the horizon each night for the full moon varies throughout the year about as much as the length of the day. Near the winter solstice (December 21st), the full moon appears above the horizon for almost 15 hours, near the summer solstice (June 21st), the moon will only be above the horizon for about 8 hours at the latitude of Ithaca.
