Located in the constellation of Hercules, about 230 million light-years away, NGC 6052 is a pair of colliding galaxies. They were first discovered in 1784 by William Herschel and were originally classified as a single irregular galaxy because of their odd shape. However, we now know that NGC 6052 actually consists of two galaxies that are in the process of colliding. This particular image of NGC 6052 was taken using the Wide Field Camera 3 on the NASA/ESA Hubble Space Telescope.

A long time ago gravity drew the two galaxies together into the chaotic state we now observe. Stars from within both of the original galaxies now follow new trajectories caused by the new gravitational effects. However, actual collisions between stars themselves are very rare as stars are very small relative to the distances between them (most of a galaxy is empty space). Eventually the galaxies will fully merge to form a single, stable galaxy.

Our own galaxy, the Milky Way, will undergo a similar collision in the future with our nearest galactic neighbor, the Andromeda galaxy. However, this is not expected to happen for around 4 billion years.

What a wreck. Terrifyingly beautiful. I feel sad for the sentient life forms on the planets affected by this collision. But perhaps most or all of the Stars and their planets managed to survive according to their distances from the melee'. If their scientists knew that this was coming, perhaps they may have taken steps to save at least some of their "people". Hope springs eternal.

There are some very complicated issues of galaxy formation. Unfortunately, here is the same problem as with the stars. The origin of galaxies remains unclear, in spite of huge activity in the field. What the "formation" means? It means that we have the material that is assembling into galaxies.

I imagine four billion years fro now, there will still be looneytoon woomongers faction to insist that the Milky Way Galaxy is being born out of the Andromeda Galaxy.

Versus the tooneyloony woopeddlers faction demanding that the Andromeda Galaxy is being born out of the Millky Way Galaxy.

After Aeons of Time?
The pathetic bleating of the frauds will go on.

Paying some attention to the time scale involved here would help your thinking and lessen your sadness.

Time scale? These Events have nothing to do with time as you believe you know it. The collision was destined to happen due to the TRAJECTORY and VELOCITY of the two galaxies - nothing more. You can add Gravity to the mix if you like. But your understanding of time did not make these two objects come together within the SPACES that they occupy.

Mar 09, 2019
Dudebro doesn't think time has anything to do with velocity.

Teh stoopit, it burnz.

It's like saying distance doesn't have anything to do with space.

It's amusing watching a troll squirm.

I would think that looking for two galaxies approaching collision would be a good test for dark matter. The outer dark matter rim of the approaching galaxy should collide with (and visibly disrupt) the target galaxy prior to the visible part of the approaching galaxy.

Mar 10, 2019
Actually it's not a "rim." It's a "halo" which is globular, at least the way astrophysicists use it. And the only way they can see it is with gravity effects either on the stars or on light by lensing. So it's not quite that easy. But do keep thinking; it's a good habit.

Mar 10, 2019
Halo is a better term. Thanks. However, there are additional effects when galaxies collide that you overlook, my friend. For instance, shock waves cause new star formation, etc. The shape of the galaxy is affected, as for instance when spiral galaxies collide and create an elliptical galaxy. This is the result of not only the visible stars of the colliding galaxies but also the interstellar gases. The question I am considering is what happens when the hypothesized halo of dark matter passes through the target galaxy. Are there similar observable effects? The period of galactic approach, when dark matter preceding the central galaxy enters the target, would provide an exceptional observational window in which the effects attributable solely or primarily to dark matter might be observed, and perhaps reveal some of the properties of dark matter.

Mar 10, 2019
Careful with that hypothesis about disks merging to form ellipticals. The astrophysicists don't think it happens that way any more. It was a good hypothesis while it lasted but the dynamics just don't support it.

For a good example of a "pass-through event" see the Bullet Cluster. You will find lots of interesting gravity effects from dark matter there. If you'd like an article I can provide one; anything for someone who can think. ;)

Mar 10, 2019
Hmmm, I see a few solid journal articles cited with links in the Wikipedia article on the Bullet Cluster. Also, a discussion of gravitational lensing as per your earlier comment. But sure, I'd appreciate a good article reference.

Mar 10, 2019
You have as good as anything I'd get. Carry on.

Oh, Da Schitts, is that what your boyfriends tell you -- It's not a "rim", it's a "halo" job.

LMAO.

LOL I see that Da Scheide has made a new account yesterday to agree with everything that Da Scheide says, proving once more that Da S uses more than one computer to log on in his various personalities so that he can be in 2 or more physorg phorums at once. Pretty soon, he will surpass the numbers of SpookyOtto's many accounts.

There have been too many instances of such as Da Schniebo creating sockpuppies for the purpose of making other commentators believe that there are those who actually agree with him. All the science that he claims to know and tell about are readily available on Wiki and other science websites, papers, journals, and all are on the internet. He loves attention and adulation, so if you are really new here, don't be fooled by his exclamations of knowing more science than anyone else.
He might ask for your personal and public information. It would be unwise to reveal them in this public website.

@Russell Gm.
solid journal articles cited with links in the Wikipedia article on the Bullet Cluster
Beware old BB-biased articles; they're obsolete/obsolescent since recent mainstream astro/cosmo discoveries/reviews based on new/better telescopes/data/analysis using more realistic observations; as opposed to old suppositions/interpretations biased by (now falsified) Big Bang hypotheses/claims which previously (erroneously) asserted CMB, 'exotic' Dark Energy, 'exotic' Dark Matter and (illogical) INFLATION etc, 'supported' BB 'model'. For example, I long ago pointed out that the 'dark matter' was ORDINARY stuff, not 'exotic'; and that VAST quantities of it would be found (by newer telescopes etc) in DEEP SPACE regions ; which it IS, even as we speak. I also pointed out that Bullet Cluster 'interpretation' was wrong; since the ORDINARY (previously too faint, but now being detected) 'stuff' was ALREADY THERE in intergalactic space BEFORE collision! Beware old fantasies. :)

You know, accusing people of being sockpuppets when they're not has a really serious tendency to piss them off.

Maybe you should go back to licking your dog's vagina and stop posting bullshit that anyone who knows any math or physics can see is psychotic on the physics site.

Just sayin'.

Yes, I agree, DS. It certainly pissed me off when, for years, you and the CS-gang were doing to me.

ps: Please address your posts so the readers can see at a glance to whom you were responding. Thanks. :)

FYI I've reported all parties to the moderator. Hopefully everyone will be ejected from phys.org. This thread is low even for the internet. I'll be signing off permanently, so everyone have a nice life.

Thanks; and the same to you, mate. Cheers. :)

That's a shame.

Reported many times. The mods never do anything.

If someone insults my wife I no longer respect boundaries.

In a bar, you don't even mention my wife. Or you get glassed.

Besides being an intellectual bigot, why do you have to be a social one as well ?

Are you scared of gays because you have hidden homosexual tendencies ???

This is not the first time I am seeing homophobe-type remarks coming from you @antigoracle.

Embrace the penis @antigoracle, don't be afraid of it, your life will be easier if you love your true self, there is no need to hide anymore, accept your love of man.

We will embrace you and your newly accepted love of man. :)

From your fellow gay
Big hugs @antigoracle

Answer these 7 questions, Da Scheide.
1. What is time made of?
2. Does your wife still use a dildo?
3. Does her vayjay still stink like rotting fish?
4. Is it true that you're gay and love a big coq up your arse?
5. Your wife says you can't get it up. Is she telling the truth?
Oh, so it is true.
6. Tell us about your boyfriend, Da Schniebo. Does he cum in your moof often?
7. Your wife says that you hate sex with women. Is she right?

Aaw, the epitome of a physics discussion with an uneducated mushroom tied up with teenage insults about cocks and fucking wives...

You small dick, small dick flappy, wife cheat on you, wife puss fishy, you gay, you gay love cock, you mouth love cock, you wife love neighbour cock, cock in the arse...

I bet I can shut you up with just one question...

Answer me this :
2+2/2= ?

Oh you missed class that day ?

I'm not sure why the present troglodytes think that calling people gay is an insult, but ok...

Like you, mate, I am appalled by the levels of personal insults and nasty feuds. Which is why for years now I have been trying to get @Captain Stumpy, @Da Schneib and 'the gang' to stop setting such bad examples with their personal insults/trolling 'tactics/campaigns' against any poster they do not like (even when that poster, eg me, has been polite/correct on the science).

The following link contains one (of many over years) instances of the bad example set by @Da Schneib et al:

https://phys.org/...urn.html

Note @DS's post:
@FreddyJoe ....... Go back to your barrel fire and your sister, trailer trash.
Recalling that "What goes around, comes around", it is no surprise that others are now doing to DS what he has been doing for years.

Mar 13, 2019
Well. I for one can see why you "gaily" woomongering trolls hate Da Schneib so much.
He is correct in the Scientific evidence he presents.
While you cesspool wallowing fakirs are consistently wrong at everything you pretend to know.

I trust you weren't including me in your general 'woomongering trolls' comment, mate. Especially since many times I have been the correct one who had to dispel DS's own 'woomongering' while suffering his unwarranted insults and accusations of 'lying' etc.

ps:
Anyhow, mate, in future please make clear whom you are addressing/referring to in the thread, so as to avoid innocent bystanders being mistakenly implicated by your feuding exchanges with those whom you are actually feuding. Thanks. :)

RealityCheck has a point. I don't know everything that RC posts, but they seem to be calling out a couple of the notorious climate science deniers in another thread, so I am withholding judgement for now, pending evidence.
