Report on Moon Watching Meeting for the Total Lunar Eclipse on Saturday, April 4, 2015

 

On Saturday, April 4, 2015, our first Moon viewing meeting for the total lunar eclipse was hosted by an art gallery. First, Dr. Masatoshi Ohishi described how a total lunar eclipse happens.

 

A total lunar eclipse occurs when the Moon passes into the Earth's shadow. In the Middle Ages, it was believed that the Earth was flat rather than a sphere; so, the round shape of the eclipse shadow was a topic of debate among the astronomers of the time. Dr. Ohishi also explained that the Moon appears red during a total eclipse because blue sunlight reflected from the Moon is scattered while passing through the Earth's atmosphere.

 

 

Because the Moon's period of rotation is equal to its period of revolution, we can normally only see its near side. The far side of the Moon is completely covered with craters (apparently caused by meteor impacts).

 

Dr. Ohishi showed an "Earthrise" video over the Moon recorded by the lunar orbiter spacecraft SELENE (also known as "Kaguya").

In the latter part of his talk, he demonstrated "Mitaka," free planetarium software developed by the National

 

Astronomical Observatory of Japan (NAOJ). This software provides large-scale, rotatable views from Earth of the Solar System other stars and galaxies. He mentioned that the rings of Saturn are about 10 meters thick.

 

We also heard that the age of the Universe is 13 billion years. The extent of the Universe that scientists have been able to observe so far has been limited by the distance light can travel in 13 billion years. We do not yet have a firm understanding of what the Universe is like beyond this range.

 

After eating a meal together, all the participants briefly introduced themselves.

 

At 8:50 pm, we went outside to observe the eclipse. Unfortunately, the weather that evening was cloudy, the Moon was intermittently hidden by clouds, and we could not get great photographs of the eclipse. (Checking the Internet stream from the NAOJ site in Mitaka, Tokyo, we saw that the sky was heavily clouded there too.) Here are some photographs of the eclipse taken by Dr. Ohishi.

 

Back inside, we watched an Internet stream from NASA that one of the Inacafe science cafe staff had found.

 

We offer our thanks to Dr. Ohishi for his talk, to the Inacafe staff for their help, and to everyone who attended. The slides shown at the meeting can be viewed at the address below.
