Every galaxy has the same apparent brightness as an equivalent sized patch of the Milky Way (luminosity law).
The magnitudes given for objects can be deceiving for this reason. Two galaxies of the same magnitude can be very different in surface brightness.
With GOTO systems today, it's much less frustrating than when star-hopping was the only option.

You know at this rate someday we will be able to look far enough to see our own a$$es! No, I heard it was Uranus.

Go see "Serenity" for some space opera entertainment.We got the Firefly DVD set the other day. Awesome show, can't understand why Fox gave it the shaft like they did. Kind of makes me think of The Outlaw Josie Wales set in space.
I just hope it gets picked up by the SciFi Channel and put back to back with Battlestar on Friday nights.

There is no way in heck that we are the only intelligent species and Earth is the only habitable planet in this universeThat's right! And that's why it is our duty, nae, our biological imperative to:
1. Crack the secrets of physics;
2. Find ways to travel to the stars;
3. Conquer as much as we can, terraforming all the way;
4. Put free men and women on so many worlds that no single catastrophe could ever wipe us out completely.
5. Look back at the UN-controlled stay-at-homes on Earth the same way we present day Americans look at our Euro-weenie cousins, and laugh our a$$es off over rounds of jinnintonix.

We could also look something like this:I've read about that. Barred spirals aren't supposed to be that common, either.

Yes, I was surprised to learn of the new Spitzer results. The picture I posted is NGC 1300, an extreme example of a barred spiral.
Thanks for the link.

Not to say they are making visits to toothless men
That's exactly right! You have to understand how these space aliens think. They spend years looking for one person that no one will believe, and then while he is stumbling in the desert in a drunken stupor - whammo - they grab him, take him to their spaceship and perform all sorts of really weird experiments on him. Then, just to make sure that no one believes him, they telepathically beam messages to his brain that say: Jim, you are the special one - tell everyone of the great space thermos!

We like to live on the Gulf coast, in the Yucatan, on the slopes of volcanos, on top of the Ring of Fire, at the base of the biggest, most active mountain building chain, anyplace that faces eventual natural catastrophe. Why not go out to space and live with a couple millimeters of aluminum between us and the absolute eternal vacuum or on a distant planet where the flux lines are inverted and make our brains turn inside out. Sure, that's the thing to do: go out to live floating on a methane sea on Titan and call FEMA when there is a moon tsunami.
