so is it like in movies, when you give birth to your only child, you die?

Hello All

Woman

and deep field study

and Black Holes go hand in hand.

OK!!!!!!!!!! enough of woman.

History shows us that, that type of thinking takes our focus away from the main event.

I hadn't realized the main Hubble scope was down. That's no good.

As far as women and the universe.. It's all in the eyes of the beholder.

:-D

That is correctly called "jerking off the IM".

Do you know that story about onanist diary?
  • Mon, today I did it with my right hand. Oh that's great uhhh ahhh...
  • Wed, today I did it with my left hand. Damn, that su(ks.
  • Fri, today I did it with a woman. That's even worse than my left hand.

They will have mr hubble back on his feet in no time.

It will give us time to catch up on the discussions.
I hope your right Harry! I really enjoy the beaetiful space veiws that Hubble gives to the world.

Now that Hubble decided to sleep, we may never know the orbit of the two new moons..........at least for another ten years or so. hey NASA, build us another Hubble. 8)

Hello Pete

Thats why God created the computer.

Email her your thoughts.

And that cyber thing, that everybody talks about.

Well, if all the women are on Venus, let's just say I have some rather important questions to ask my "girl"friend...



All right, it was a joke! I don't have a girlfriend.

Hello Pete

This is a great created image of the system.
Nice. Looks like that screenshot was taken in Celestia, a space simulation in which you can fly basically anywhere in the observable universe.

This is extremely troubling news to me. :)

Tradition!

Harry is probably right. Hard to break old habits, even for the IAU.

Personally, I agree with Nick. Pluto should be classified as a KBO, since its characteristics (small, icy, highly eccentric and out of plane orbit) put it solidly in that category. "Planet" should be formally defined to include only rocky or gas giant bodies with near circular, in-plane, primary solar orbits, of sufficient size to be gravitationally compressed into roughly spherical form. Mercury should roughly define the baseline for maximum eccentricity, although size could certainly go lower.

As noted by Nick, under my definition, Earth - Moon might be a double planet. None of the gas giant satellites would qualify, though, because they primarily orbit their (vastly more massive) planets, not the sun. Earth and Moon have an unusual co-orbital relationship because of their relatively similar size, plus the fact that Earth does not have any other satellites of its own.

I would be interested in hearing more opinions from our esteemed community, including definitions of planet that might include Pluto.

yeah, that will warm them up a little.

Hello Nick

I thik Pluto will remain as the 9Th planet.

It has tooooooooooo much history.

Pluto and it's moons or an asteroid with lots of others?

by Nick » Sat Jun 24, 2006 8:10 am

Soon Pluto could be declassified as a planet to an asteroid or Kuiper Belt Object (at the IAU meeting in August I think), or lots of other things could be included as planets - including by one definition our moon and numerous moons of the gas giants.

Anyone going to start a sweep for guessing the number of eventual planets we have?

Nick

P.S. Does anyone remember a BBC childrens tv quiz last Christmas where 10 planets was given as the correct answer? I thought it was still officially 9...

Then there's Jupiter and Saturn that have more moons than you can shake a stick at. :lol:

Wadsworth,
Welcome to the jungle. To answer the question posed in your signature,
Woman would have to be more complex in mans eyes because we have invented ways to view and attempt to understand the former but the latter can't be seen through the Hubble. (and if we attempt to view the latter through terrestrial telescopes, we get in trouble)

I bet my a*s in USA you could file a suit against God for earthlings discrimination, seeking unspecified damages. Then, the jury would probably rule to oblige Him to put extra moons in orbit during next month, so that you could sue again for destructive tides.
Good ol' US of A.

They are named Hydra and Nix now

Very cool Qev, i never knew that before. Looking into it further with the links you gave, I found they aren't technically "moons" of Earth. But they do co-orbit the sun with Earth, making occasional close encounters. Their peculiar orbits do make it seem as though they are orbiting Earth, but in reality Earth's gravity is really only affecting their orbit around the Sun.

And thanks harry, I remember the discovery of extra moons around Pluto but that was the extent of what I heard. It's nice to hear more about something I had interest in but had forgotten all about :)

Double planet; I like that. Interesting subject matter!!
