... Munching on Lunar Cheese . ... Rarely have most of us really watched a lunar eclipse. Let's observe the lunar eclipse this month and see what the shadow-play can teach us about Earth and its little mate. ... My grandparents came out, we sat on bales of hay in a field, ate our hot dogs and roasted marshmallows, and watched a huge full Moon fall into Earth's ruddy red shadow. ... The ancient Greeks knew this, too, and they saw Earth's circular shadow on the Moon during lunar eclipses. ...

... Bad Astronomy . ... I think I will break from my usual format of Bad Astronomy/ Good Astronomy by saying that the way we define seasons currently is not strictly bad, but I feel (in my opinion!) that it could be better. The definition of when the seasons begin is at the moment of solstice or equinox; that is, winter (in the north) starts on December 22 nd and summer starts on June 22 nd . ... Now imagine breaking up the Sun's 46 degree up-and-down yearly swing into 1 day intervals. ...

That triangle has the same proportions as the much larger triangle ABC, and therefore, if the distance B'C to the thumb is 10 times the distance A'B' between the eyes, the distance AC to the far landmark is also 10 times the distance AB. ...
