Thank you: that explains it for me.

Thanks a lot for taking the time to address my concerns. My apologies for insinuating that the picture was doctored.

Cheers,

Re: A Galilean Night (Oct 23rd)

Actually, Jupiter and Earth (and all the other planets) are somewhat off the ecleptic. In addition, Earths equator and the Moon's orbital plane is tilted from the ecleptic, as is Jupiter and its moons. So you think that the moon being 2 degrees higher in the sky is due to these aberrations, and the...

A Galilean Night (Oct 23rd)

Hi, Looking at the photo supposedly showing the Gallilean moons of Jupiter, I was immediately struck by the fact that the moons are in the wrong plane. Surely they should line up with the moon since the Earth and its moon, and Jupiter and its moons are all in the plane of the planets. So the photo i...

Hole in Mars (APOD 28 Sep 07)

As soon as I saw this I thought "This is obviously the launch tube for the Martian missiles to earth", since I've just seen Jeff Wayne's War of the Worlds Musical (Auckland, New Zealand 28th Sep 07).

Love those coincidences :-).

Cheers,
Brent.

Re: APOD 2007 June 19 - Eris

[quote="Angus McPresley"] I came to this forum to say almost the exact same thing. The sun is WAY too big. It would look more like a bright pinprick from that distance. [/quote] I also came here to say the same thing. And also to rant a bit :-). [rant] Why is it that virtually every artist...
