Astronomers observe objects in the sky, not the Earth.--Dgbrt (talk) 11:19, 7 August 2013 (UTC)

Are you sure “Sphere” refers to “hemisphere” and not simply to earth? After all, she’s trapped on earth and not on the celestial sphere. Quoti (talk) 11:24, 7 August 2013 (UTC)

It's the hemisphere, see my comment above.--Dgbrt (talk) 11:46, 7 August 2013 (UTC)

I'm assuming you're referring to the "light-sphere" whose origin lies at the astronomer's location, and thus the universe always being bigger than the places he can physically visit. Still though, the statement "They can't travel to the places they observe" isn't accurate. We've been to the moon for instance. And then of course, there are always the unknown unknowns of the universe and interstellar travel. 220.224.246.97 12:19, 7 August 2013 (UTC)

I read it as earth. It's a sphere and we're all trapped on its surface and astronomy classes make you aware of this fact more than your everyday experiences. Also, doesn't "hemisphere" mean "half sphere"? like northern and southern hemisphere of the earth? Peter (talk) 12:48, 7 August 2013 (UTC)

Do we maybe have a reference to 1246? 217.81.31.20 11:37, 7 August 2013 (UTC)

That comic belongs more to space science than to astronomers.--Dgbrt (talk) 11:46, 7 August 2013 (UTC)
