Mysterious Stars Surround Andromeda's Black Hole
UltimaGuy writes to tell us that Yahoo is running a story about a recent discovery that shows the source of strange blue light coming from the center of the Andromeda galaxy. The light is actually a cluster of stars circling the galaxy's central black hole with immense orbital velocity. From the article: "Such frenetic activity was thought to prevent star formation. Stars form when a knot of gas and dust collapses under its own gravity."
It's the resurgence of K-Mart!
A feeling of having made the same mistake before: Deja Foobar
...that we are too far away to send a probe into this black hole.
Speaking of stars, what is the source of the heavier elements? I thought most came from star fusion, but I don't think that can account for all the elements. Plus planets seem to have a higher distribution than hydrogen-rich stars.
Yeah yeah in soviet russia...grits...fail it...etc...

If we don't fight for ourselves no one will.
Stinking ricers have taken over a whole galaxy. If you think galactic undercarriage lighting is bad, wait till you hear them blasting that galactic bass late at night.
Elements past iron can only be created in a supernova explosion. Google on "supernova elements" for more information. Of course, the element synthesis during a supernova explosion is due to fusion, but I'm not sure one could call it "star fusion".

Wouldnt matter too much...our Milky Way and Andromeda are on a slow collision course anyway - by the time an ejected star got here, the rest of the galaxy would be right behind it. But no need to go hide in a cave just yet, we've still got about 3 billion years.
Yeah, cause God forbid, in 2.9 million years we'd all be dead!!
No... Stars form however they damn well please. Our current models suggest it is done under their own gravity, but our models are not reality. They are our understanding of reality and are modified or thrown out when we find our understanding is wrong. The universe is always right.
P.S. Sorry, it's one of my pet pieves when someone says "that not how physics works!"

Umm, dude, the stars in question are at the center of a completly different galaxy. Even if by some miracle of probability they did come in our direction, our sun would have gone nova by the time they arrived.

Sounds similar to Saturn's rings. A ton of matter spread into teeny blocks in space by tidal forces, but still with enough mass to pull together into a bazillion little blobs. Perhaps the radiant matter/antimatter/energy from the black hole (I'm fuzzy on Hawking's theory on the subject) is heating the surrounding star-spray enough to light some of them?
When I first read this I imagined some sort of weird high profile skin flick staring a bunch of 'mysterious' dudes and a hot black chick named Andromeda.

Ok, I was guessing about the nova part. I didn't know off-hand how far away andromeda was.

... Since that has SO much to do with a cluster of stars in another galaxy.
well....i haven't read TFA, but i'm assuming that the stars are going at a fraction of the speed of light, which as you all now is the speed limit in the Universe...(at least that's the theory)
:D)
but even at the speed of light it would take something from the Andromeda Galaxy a few million(/billion?) years to get here....
(of course the light is only reaching us now, so the stars might be half way here by now
and even if you think you'll still be alive by then, the chances of them being on a collision course with our galaxy (let alone Earth) are REALLY small.....
oh...and the energy necessary to make leave orbit (considering that it's a FREAKING star, orbiting a FREAKING black hole!!!) is...well....a LOT!!!
IANAA, but could these stars have formed prior to being caught by the gravity of that black hole?

Just this guy, you know?
Maybe this group of stars is not a natural phenomena? Que the twilight zone theme.
All kidding aside, they could have formed outside the vicinty and got pulled in. What keeps them from ripping apart from tidal forces is interests me.
It's the terrible secret of space!
The owls are not what they seem
If it appears to be physically difficult to explain these stars, perhaps it is an artificial constuction. I'd expect an advanced extra-terrestial civilization to exploit the immense power of the galactic core black hole. Who knows what they are doing with it? Sustanence? Wormhole transport? Communication? Entertainment? Maybe one hundred infant stars whizzing around the center has something to do with this.
DUDE!!! holy shit. As you probably know, this discovery actually happened a while ago in time (cause of the time it took the light to travel). So the star could be flinging itself at us AS WE SPEAK. It could be __cking halfway here ALREADY!!!
DUUUUUUUUUCK
... the same thing about Pamela Anderson. She's had some strange stars surround her black hole. Like Tommy Lee or Kid Rock.
"You'll get nothing, and you'll like it!"
According to Here Our sun will still be burning brightly.

According to the article, it should happen in about 3 billion years
On a side note---considering the lifespan of planets, galaxies, universis - it is kind of depressing we won't be around to see spectacular things (i.e. Star Trek space travel). Ah I need to find me a "Q" and get them to let me join up

are correct. Thanks for the correction.

The sun won't go nova in any case; it's too small.
Andromeda is the closest major galaxy to the Milky Way, a mere ~2 million light years away. It's moving toward us rather rapidly though, and the two galaxies should collide in about 3 billion years; if one of these stars was "thrown free" (how exactly?) it might get here well before that, but your basic point is right on: By the time it got here, there is basically no chance that the earth will still be a habitable planet.
Of course, the chance of an object randomly thrown from that far away hitting the earth is like... Let's see, if I randomly threw a dart (really hard), the chances of hitting the bullseye of a dartboard on the planet neptune... are much much better.
My explanation is almost as bad as the fundamentalists. If something complicated happens, they say God made it rather some scientific explantion. I'm just substituting advanced aliens for God.
Subject said it all... but since a comment is required, here it is.
what I've heard is that while galactic collisions look like all holy hell breaking loose, the stars so rarely pass actually close to each other that they never meat - it's like two clouds of sand passing through each other. The only worry is that something massive brushing within a few lightyears of our solar system might screw with the oribits.
We get a slow expansion to red giant, then it peters out to a dwarf. I think we at least get a planetary nebula in the deal.
I think this is the first evidence of galactic NASCAR.
From the subject line, I was looking forward to reading a pithy and scathing remark. Now I have to go kick someone.
Are there loud "pffffffffftttttttttt!!" engine sounds and ground shaking bass noises being emitted as well? My guess is Andromeda just picked up one of those lame "soup up your bad little import star with blue lights" kits at an auto parts store.
I'm thinking more like blue as in Vedrans, powered by the rapid rotation of Gene Roddenberry's corpse, and all centered around a 140-million solar-mass abyss of suck.
I think they are just trying to make a new baby galaxy!
TAKE THE STAR KNOT!
but maybe we are ALREADY in a black hole... we ARE the grain of sand in some black hole in some part of some universe...
Staying one step ahead!
I've noticed that sometimes when dealing with spiral phenomena (hurricanes, tornadoes, whirlpools, etc.) there are secondary, much smaller spirals that are thrown off from the main body. Could this be in effect here? Could the black hole be throwing off gravitational "eddies" that cause stars to be formed?
"Mysterious Stars Surround Andromeda's Black Hole"
Thats just rude to refer to Kevin Sorbo's career that way. Sure I know he sucks in stars that are never heard from again, but thats no cause to put the man down.
I couldn't fail to disagree with you any less.
Why can't people just say it. Things like this are the way they are because God wanted it that way. "The formation of these stars goes against everything we know (should be speculate)." 12 billion years...sure, why not. Thats the only way they can explain their theories because there is no proof from 12 billion years ago. You think that if God can create life, he can make something old too?

Let's watch him try to argue that intelligent beings are sending us a message as he's determined a pattern in the ratio of the radius to the circumference of the orbits...
It's approaching PI... Must be aliens!
Actually, God just installed a neon kit to Andromeda. I hear he's working on a killer stereo next (gonna turn a couple of the larger solar systems into subs). If we start hearing this gawd aweful thumping eminating from Andromeda, we'll know he's done (BTW, I know that normally sound can't travel through space, but we are talking one seriously kickin stereo). He's still waiting to install the larger spinning disks on Andromeda's hub.
the stars so rarely pass actually close to each other that they never meat
That's good. Seeing two meating stars is not for the faint of heart.
Just that!
Just doing some quick and dirty estimations, the messing with orbits issue seems pretty unlikely. The earths orbit, for example, would only be disturbed by something pulling different amounts on the earth vs. the sun, because the earth was closer to it or further from it. It would have to be awfully close for the distance from the earth to the sun to be very significant. Even at 1 light year, we're talking something like 1 part in 100,000. You'd need something very massive, passing quite close, and very quickly. The quickly part is there, but the other two are a pretty tiny probability.
The galactic collision will no doubt wreck all sorts of re-arangement on the massive scale of galaxies. Any observers concerned only with the relatively minute scale of a single solar system will presumably not even notice.
Not, as noted, that there is much chance those observers will be human.
http://en.wikipedia.org/wiki/Andromeda_Galaxy
Wiki says 2.9 million light years distant.
So yeah, what we are seeing is ~3 million years ago. The OP was obviously trying to be funny, but if Andromeda were to try to fling a star across intergalactic space towards us, it would take hundreds of millions of years unless there is some way to accelerate an object the size of a star close to the speed of light.
There is much cruelty in the universe, John.
Yeah, we seem to have the tour map.
...in the so-called "Theory" of Gravity. (what, did you think I was going to say goatse?)
When will those fancy-pants university astrologers accept the truth of Intelligent Falling. It's in all the news, so it must be true.
Actually, the discovery happened just recently - the actual event happened a long time ago.
But regardless, you're actually exhibiting a common logic falacy. Because the star is travelling at less than the speed of light, it's impossible for the star to "sneak up on us" by arriving here before it's lightwaves do.
In any event, my original post was just a joke.
What the astronomers are seeing is the lights of millions of blue screens of death!

Consider the source. Yahoo gets a bunch of bad press for snitching on poor Chinese users, infesting users computer with spyware and a bunch of other evil-Yahoo stuff. SO what do they do? "Don't worry about us, look at these stars being eaten by a black hole!! OMG, we're all going to die!!!"
Having the Earth "pulled out of orbit" by a passing star isn't the only problem. Consider a close approach at right angles to the ecliptic. As the intruder passes, it will perturb the Earth's orbit toward it, making it more eliptical than it is now. Not, of course, enough to cause a collision, but possibly enough for climate change; hotter summers and cooler winters for the Northern hemisphere, where most people live. (Assuming it came while there are still people living here, of course.)

Our galaxy is "quiet" because the black hole has "pushed" the surrounding matter away from it so that it no longer has any significant incoming matter. A galactic collision would probably play hell with this balance, though, sending material into our very own supermassive black hole. When this happens, the levels of radiation could be so high that small perturbations in the earth's orbit will be the LEAST of humanity's concerns.
The good news is that at the very earliest, the Milky Way won't collide with another galaxy for several million more years, when Andromeda MAY hit us.

Some black hole rotation could be caused by matter falling onto the event-horizon, imparting its kinetic energy onto the black hole, causing it to start turning.
I can imagine that as a method to start black-hole rotation, but what I can't figure out is why a black hole such as cygnus x1 ISN'T rotating.
Maybe cygnus x1 originally inherited its progenitor-star's rotation, but matter falling on the even-horizon since has braked the rotation? Doesn't seem likely...

so was mine. Also, the star could actually be travelling at whatever speed it wants to travel at. It pop into my living room based on certain physics theories going around, and I don't even have a living room.
It's a reality show.
The Guide is definitive, and Reality is frequently inaccurate. I don't see how the universe fits into this, I mean, what's it know? Yeah, that's what I thought.
Actually, currently the Earth is closest to the sun in Northern Hemisphere winter. For the effect you describe, it would have to get much more eliptical, and in the opposite direction. But that's nitpicking. I'll happily agree that actually pulling the earth out of orbit around the sun (which is just stupendously unlikely) wouldn't be necessary to cause a problem; any significant disturbance to the orbit would do it. I was just pointing out that to cause a significant disturbance in the earths orbit would require a combination of mass and closeness of aproach such that the odds very heavily favor passing all the way through the Andromeda galaxy without it happening.
"screw with the orbits" is putting it mildly. The gravitational forces of two colliding galaxies will pretty much rip the galaxies apart and throw a lot of stars on pretty wild orbits.

It will go nova, just not supernova. This will happen when the H is just about used up and will be the beginning of the Sun's shift to being a red giant.
(IIRC, IANAA, void where prohibited by physical law.)

Post in haste, repent at leisure - I checked Wkipedia and what I said is correct except technically it isn't called a nova, which is a word reserved for somthing which happens in white dwarfs in binary systems. But the Sun will use up the H in the core, and eventually expand into a red giant 1E3 - 1E4 times more luminous than now in a series of steps brought on by "He flashes" which might as well be novae as far as surviving them on Earth is concerned.

Well, not that a remote star passing through our solar system is particularly likely either, but it's worth pointing out that a star passing within twice the radius of the Oort cloud would be enough to significantly alter our planet's orbit, to the point where our ecosphere would be annihilated, and if we were lucky maybe we could hide from new deadly weather under domes.
Granted, stripping two digits out of that mantissa makes it insignificantly less spectacularly unlikely.
StoneCypher is Full of BS
That said, I think that Christians can investigate the creation scientifically. We already know the WHO of the creation. But nothing is stopping us from finding out the HOW and WHY.
If you allow yourself to engage in such unscientific thinking that lead to your "knowing" who, you're likely to find yourself having trouble being scientific about the how and why.
For example, you may attempt to impute the why of something to "god's plan".
Or it may lead you to believe c really isn't a constant, since god can change it if he wants, or that Quantum Mechanics is flawed because "god does not play dice".
I mean, just imagine a science book that says, "the Earth's rotation is the cause of the day, in which the sun appears to circle the Earth every 24 hours, except when god decides to stop the sun in the sky."
You just can't do it. God and science just can't directly mix, because wherever the answer has been "god", science has always come back with, "no, it's this natural cause".
Of course, you may not suffer from any such problems, but the mere act of believing god as a scientific fact (who) stacks the odds against you.

Blue stars tend to be hotter and younger than red ones. They have a shorter life span being blue
we figure, since they are burning up fuel at a much higher rate than red stars do.
Hence the idea that they must be young.
However, it may be a plausible idea that these stars, being under such extreme circumstances,
within 1 lightyear of a 140 million solar mass black hole, emit blue light not because
of their high internal fuel consumption, but because of external influences.
Being bombarded by highly energetic particles, exposed to immense gravitational and/or magnetic
effects, speeds, etc..
The thought would be that the disc of stars around the black hole is actually more or less uniform where age is concerned, but that the ones closest to the black hole undergo some effects that make them turn blue.
If I was a type 3 player in this universe and wanted to make my presense known maybe I would place stars in unusual places.
Eventually other would figure it out and maybe there is a message to decode.
They should look for mathematical alighnments in the stars to see if they are unnatually positioned.
Would be pretty cool.
