I don't understand how pictures like this are taken. Do we actually send a satelite that far out?
>> Anonymous
>>74422

It would be impossible with current technology to send a satellite that far out. So far there have only been 4 artificial satellites to actually leave the solar system (with one on the way).

The Hubble Space Telescope is in a low earth orbit, I think like 600 km or so above earth. It gets the images from LOOOOOONG exposure times as well as the advantage of being in space with hardly any air to distort the image.

Another thing is that many Hubble images are false color, that is several areas of visible and invisible light are captured then combined or enhanced for detail etc.

You can see some of these things in clear un-light polluted skies with your naked eye. Or a modest telescope.

So what would these things look like if you were in a spaceship and walk by a window? Not as pretty? Or is it impossible to tell?
>> Anonymous
There's a lot of ZOOM going on too. Don't forget the zoom.

If you were in a spaceship and saw this out the window it'd be a tiny dot. If you were still in this galaxy anyway.

Well, ya, but I was referring to the coloration and general prettiness of all celestial bodies. Our feeble monkey eyes wouldn't see them the same way as they are in teh purdy pictures? =( Anyone have any technical info on exactly how different they would appear if you were to pass right by a nebula or other such awesomeness?

Depending on what you're looking at little zoom may be in order (but usually isn't the case). The andromeda galaxy is the width of 4 full moons as seen from earth. But, very faint. So it doesn't look as pretty as in pictures, that have that long exposure time.

As for things like being in/near a nebula. I don't know.I mean it's just a very diffuse gas that spans a lot of volume (think light years) and reflects light from nearby stars. If you were in a nebula you might not even notice. If you were next to it, it would probably also be faint.

You know, we're on a collision course with Andromeda...but it'll take millions of years.

Sadly, we already know our fate is one of two things:

1. We will be ripped apart by tidal forces, and massive radiation surges as the Andromeda and Milky Way collide, or....

2. We will be ejected out of the Milky Way galaxy, and be a lost star in the interstellar sea.

Rofl, are you kidding me? That may be the planets fate, but humanity is going to destory itself in a nuclear holocaust far before that ever happens.

Man's creation will be the key to his own destruction.
>> Anonymous
actually the sun should explode even before the Milky Way and the Andromeda collide. Earth'll be destroyed even before that possibly.
>> Anonymous
>>74807
Nope, the Adromeda is due to hit the Milkty way in around 2-2.5 billion years from now. The sun is expected to maintain its current phase through another 4-5 billion years.

Then it becomes a red giant--it will never 'explode'.
>> Anonymous
Instead of talking about how we're going to all expload, why don't you talk about how we can have a fucking awesome time for the 70-80 years we have left, lol!
>> Anonymous

Nuclear holocaust won't kill everyone though. Humanity will survive, if only by a couple thousand people.

Unless we break the cycle and find a new inhabitable planet, humanity will be fucked when Andromeda comes around.

after the sun becomes a red giant, it will eventually go supernova (a.k.a. "explode"), and will either become a black hole or a white dwarf star (most likely the latter one).

here is a pic of the andromeda galaxy --- heading straight for us.

Unless that planet is in another Galaxy, I doubt that would help, it's not like that Andromeda thing is going to be a regional earth thing >P

Actually, the density of stars in a normal galaxy, is approximated to be akin to a handfull (4-6) golfballs spread across an area the size of Europe. The change that we're gonna have our star destroyed by another, is too small. Most likely, Andromeda and Milky will merge, and become one giant galaxy.

This is a terribly fascinating conversation. Could you suggest some books on all of this?
>> Anonymous
>>74903
First of all... such a merge would most certainly have serious consequences for ANYTHING, living or non-living, involved.

AND FOR THE REST OF THE THREAD

It doesnt matter if we make it to another planet/system/galaxy. Eventually, if we do last, the universe will eventually become an equilibrium of evenly spread particles.

How technical do you want to get?
If you like casual reading that is completely scientific and entertaining at the same time, I would recommend two books--both by Lawrence Krauss--"The Physics of Star Trek" and "Beyond the Physics of Star Trek". It touches on a tremendous wealth of physics.

If you prefer something deeper and more formalized, I would recommend "Who's Afraid of Schrodinger's Cat?". It's rare to find straight astronomy on the likelihood of the Andromeda Galaxy and the Milky Way Galaxy, but www.space.com has a large archive of articles on it that are quite illuminating.

Actually, that is what they think will happen. Andromeda and the Milky Way will merge and form an elliptical galaxy. No more cool spirals.

>>74811
The Sun will ultimately end up as a white dwarf, but that's after its red giant phase.
>> Atheist Jew
Anyone that's interested in this can go here :
http://www.galaxydynamics.org/spiralmetamorphosis.html

And download a vid of a simulation of the collision.

And then you can go here :
http://www.galaxydynamics.org/futuresky.html

And see what the sky will look like from Earth around that time.

In regards to the consequences of the collision, it is entirely likely that our solar system and the majority of the galaxy for that matter will be sterilized beyond any hope of survival. If you happen to subscribe to the Rare Earth hypothesis (or just the general idea of habitability), than the entire region of our galaxy that can support life (called the Galactice Habitable Zone : http://en.wikipedia.org/wiki/Habitable_zone), will be wiped clean by multiple radiation fields overlapping the galactic plane by the various supernovae and other radion-producing celestial phenomena of Andromeda. Despite that, you people can't seriously be optimistic enough to propose that humanity will survive even a billionth of a percent of the time it will take for this Galactic collision to occur.

indeed. i would be concerned about the survuval of mankind from this incident if it were to occur soon, but 2.5 billion years is a DAMN long time from now. I think we have other things to worry about in space, namely 2004 VD17 and 99942 Apophis (2004 MN4)
