Here is a pic of it with the Space Needle in the foreground.

Re: OT: Moon eclipse
I saw only Clouds...damn, i wish we lived on a Rock.Planet with NO Atmosphere ;-)
but i saw a lot of moon-eclipses before and in 1999 i went to Hungary with a couple of friends and my telescope to get a perfect view of the total solar eclipse - it was fanastic! |
Re: OT: Moon eclipse
I wonder why an eclipse would make the moon look red?

Re: OT: Moon eclipse
Not my words but accurate AFAIK...
"The atmosphere plays a role here. Longer wavelengths pass through the atmosphere more readily, while shorter wavelenghts are scattered (related to the "why is the sky blue" question). When the moon or sun is low in the sky and shining through more atmosphere, this effect is at its maximum. Note that though the reddish appearance of the moon during the eclipse is related to this, an eclipsed moon can appear red when high in the sky." So IOW it all has to do with the angle and the refractive qualities of the medium. |
Re: OT: Moon eclipse
I'd forgotten which wavelengths are scattered. Thanks.

http://www.sky-watch.com/articles/skyblue.html This also explains why the sun is red/orange, but the sky is blue. Those wavelengths that are not scattered randomly by oxygen and nitrogen travel more or less straight from the sun to your eyes, rather than at random angles like the bluish light. |
