Galaxy cluster is a star-forming powerhouse

The Olympics may be over, but in outer space, records are still being broken.

Scientist announced Wednesday the discovery of the Phoenix cluster, one of the most massive and luminous galaxy clusters ever identified. It's about 5.7 billion light years away, so we are getting a sense of it as it was at that time, billions of years ago.

The cluster has a mass of 2,500 trillion times that of our sun, said Michael McDonald, researcher at Massachusetts Institute of Technology, in a news conference Wednesday. It contains hundreds of thousands of galaxies the size of the Milky Way, in addition to dark matter and hot gas.

In a race to form new stars, this cluster leaves our Milky Way in the dust.

Impressively, the central galaxy in the cluster produces about 740 new stars per year, a rate that is unmatched by any other known galaxy at the center of a cluster. By comparison, the Milky Way forms about one to two new stars each year.

The Phoenix cluster also breaks the record for being the brightest cluster in the X-ray radiation spectrum. The gas in the cluster is about 100 million degrees Kelvin; our sun is cooler, by comparison.

More from space: searching for life on the moons of Jupiter

Scientists used the Chandra X-Ray Observatory, a space telescope, to investigate clusters that the South Pole Telescope had helped to identify as interesting. The Phoenix cluster appeared unique.

Astrophysicists are still trying to understand how galaxies got their stars. Gas needs to cool down and become dense in order to form stars, but that process is still an open research question, said Megan Donahue, professor of astronomy at Michigan State University in East Lansing. Only about 10% of the gas in universe is in stars.

In other clusters, such as Perseus, a black hole doesn’t allow gas to cool and form stars so quickly. That’s because the black hole releases powerful jets, which push gas out of the way, said Martin Rees, professor of cosmology and astrophysics at the University of Cambridge, United Kingdom, who was not involved in the research. The jets produce sound waves that release energy and help prevent the formation of stars, since the gas can’t cool.

That’s not the case with the Phoenix cluster. There’s probably a fairly massive black hole in the central galaxy of the Phoenix cluster, but it’s not putting out the same energy seen in other clusters, said Martin Rees, professor of cosmology and astrophysics, University of Cambridge, United Kingdom, who was not involved in the research.

“The infall rate of the gas is at this exceptional rate, because there's so much hot gas in this cluster, it's a very big dense cluster,” he said. “This gas is raining down, and it just can’t compete.

More from space: What we've done on Mars, and what's next

So the "tussle" between black holes and gas is won by the gas in the Phoenix Cluster, Rees said, but not in the Perseus Cluster.

"It’s by studying these extreme objects, and hoping to find more of them, that we really understand the symbiosis between galaxies and their black holes," Rees said.

If scientists could observe the cluster now, rather than as it was billions of years ago, it would be an "exceptionally bright galaxy" with a black hole with a mass of 10 billion suns, Rees said. It would not be quite as blue; blue light indicates younger stars, while red light is the signature of older stars.

    "It contains hundreds of thousands of galaxies the size of the Milky Way, in addition to dark matter and hot gas.

    Well of course it does, it contains hundreds of thousands of galaxies compared to our one Milky Way galaxy. What a complete moronic statement.

    What is being seen in the Phoenix Cluster is likely the early stages of galaxy formation following the Big Bang for that galaxy. Years ago, the formation of the universe had two competing theories, Steady State and The Big Bang. The Big Bang seems to have won Round 1, but Steady State will make a comeback once science realizes that all the galaxies in the universe were not created at the same moment in time and space. The reality is, each galaxy is formed by its own Big Bang and that is why galaxies form in different shapes and different orientations. From the Steady State side, all the material of the universe has always existed, but it is constantly expanding and contracting in a "Big Bang Cycle" that sees each galaxy having independent birth, death, and rebirth. Really, how can galaxies become this spread out if the material all originated from the same place only 13 billion years ago???

      I can agree with you where the big bang get material to produce new galaxies. As an old country boy the only way you can get new material by new life.

      Right after the big bang space expanded immensely at a speed much faster than the speed of light and all of space is still expanding because of the effect of 'dark energy' which permeates all of space.

    As much as I love stuff about outer space, I'm really losing interest in these type of articles. They all have the same theme: "We found something" - "It means nothing to us now, but might be relevant in 100 years" - "Scientists across the country are having nerd-gasms" - "Carry on"

    Honestly, we need to focus more local things in the universe. There's still a lot we don't know about our own moon, and that's right around the friggin' corner. Seriously, we could discover more new things about the moon in the next 6 months than we could about the rest of the universe in the next 6 centuries. I'd totally be more excited about discovering fossils on the moon than seeing a spec of light that could be a start cluster billions of light years away.

      What you are saying is forget all the resources that we have already established on Earth and thousands, maybe millions, of miles away and invest in new resources to go to the Moon... Do you think that we built a brand new telescope to look at this thing? Also, discovering something new about star clusters and galaxy formation is informational because it allows us to glimpse into the past of our galaxy. Moons provide very little information unless we wanted to do an excavation, which would probably require trillions of dollars to even establish a small colony on the moon. And NASA could probably develop more information (and technology) with a fraction of that trillion going deeper into space than going to the moon.

      It WOULD be exciting to discover a fossil on the moon. Mostly because, under our current understanding, there is pretty much 0 chance that there are fossils (of once-living organisms) on the Moon. If that is your reasoning... then just start digging down looking for Oompa Loompas under the Earth's crust. That would be a REALLY exciting find!

    • Duane

      I totally disagree. Science and exploration are about stretching our capabilities and understanding. Just because something is low hanging fruit doesn't mean that it is ultimately better for you than reaching further where you may discover something much more interesting or beneficial. One thing is for certain, the universe is immense and we won't really learn much about it by limiting ourselves to our own back yard.

    August 16, 2012 at 9:06 am |
    • Reemo

      It's because those earth-like planets don't give off a lot of light. You ever looked up at the night sky and wonder why you can easily see stars that are several light years away, yet you can't see Mars, which is right next door?

        Actually, Mars is very easy to spot if you know what your looking at in the night sky...when its orbit around the sun is aligned with our planet, its easily distinguishable. Saturn, Jupiter, Venus, and Mercury are planets that can be seen with the naked eye as well.

      Ummmmm space is LITERALLY DARKNESS (the absence of light) Stars & Suns (what we call stars close up) produce the light... Planets dont produce light unless they are inhabited by being capable of producing light (like us in our case of Earth) or those stars and planets are at an angle where the light given from the star can be reflected.

      EXAMPLE: If you and I are in a pitch dark room with little to no light and I shine a flashlight into your eyes then throw a baseball at your face... you're not going to see the baseball until it either crosses the path of the light essentially blocking it or it's close enough to the light so that the light can reflect of its surface. Now... if you want to continue to be sarcastic about that which you dont understand... I'm free to setup this experiment with you. REALLY I HAVE TIME. LOL.

      We don't know yet and that's the best part. Since our beginnings the human race has been on a journey of discovery, we're curious about our surroundings. It's why we came out of the caves, went over the hills, crossed the oceans, and took to the skies. Space is what is next. And who knows what the future holds.

        "We don't know yet, and that's the best part" is usually followed by a whole lot of nothing happening for the next 20 years. That's why space study hasn't become mainstream, yet. It'll be a lifetime before we make any type of relavent discovery that can be applied instantly.

      • Chill yo...

        In the lifetime of every discovery made by man there was a point in time when it didn't work or that we didn't understand it yet. That's why science is a self-adjusting process, never sedentary always changing. I'm sorry that your short attention span craves such instant gratification, but it comforts me to know that one day (maybe in my lifetime though certainly not) the very data that's being collected right now will be used in a positive and productive manor and will benefit the world.

      This is helping us gain knowledge about something which we knew nothing about before. There might not be any practical applications we can see right now, but for many scientific discoveries that is the case. No one knew how lasers, general relativity, quantum mechanics could be used, but here we are 100 years later with GPS, computers and lasers practically everywhere.

      The question "how will his help personkind move on" should be asked about reality TV and sports. For all the billions we spend on these every year, there is no intellectual advancement and is holding humanity back from its true potential.

        The Bible has been much ahead of science. Actually many are in confusion because they think that the bible denies science yet it is because science has advanced that we have understood that the bible is fact. pretty fascinating when you see that the bible speaks about the constellations before it was scientifically proven and speaks about dimensions and many more things like even the earth being suspended in space something that was just recently scientifically proven in the 16th-17th century was already testified in the bronze age about 3,500 years ago before there was any type of science technology.

      Ok, so I'm high, but even so, as physics grad I'm slightly confused. What's wrong with saying degrees kelvin? What unit should be used instead? From my classes in astrophysics I don't remember using a different unit. It's really convinent, because temperatures can get very cold in space. Consider that the blackbody of the cosmic microwave background is at 2.7K, that's not much above absolute zero, so kelvin is a fairly appropriate unit to work with when dealing with space.

    • James Hawk III

      I don't know anyone who just says "Kelvins" (any more than people say "Celciuses or Fahrenheits"). When quoting a temperature it's appropriate to specify which scale one is using, just the same as when quoting any other measurement. "Did you measure the doorway?" "Yes." "Well, how wide was it?" "Thirty-three."

      Without units, one doesn't understand the answer, does one?

      August 16, 2012 at 6:33 am |
      • Marc

        What makes "degrees Kelvin" incorrect is the fact that the Kelvin scale isn't measured in degrees. It should have stated the temperature as "100 million Kelvin"

        So it's just like saying, that door is 33 degrees feet wide, which everyone knows is incorrect.

        Hope this clears it up

    • TKO

      Science, though, says nothing about reality–it deals in measurement and repeatability. The stories that science tell through these (measuring and repeating) are notriously wrong–the "clock-like" Newtonian universe, for example, or the notion, extrapolated from darwinian theory that humans are at the top of evolutionary processes indicate that science is very good at isolating (reducing) physical phenomena and measuring them, but tells no viable stories about those "fact's" might mean. The stories we tell about the Big Bang, or evolution, or whatever are just that, stories, fantasies. So the question becomes what fantasies are real and what false? A rather absurd question when you think about it.

      August 16, 2012 at 2:33 am |
      • Elencia

        Science does not operate in terms of being right or wrong. Each iteration of its conclusions are slightly more well-informed than the last. For example, at first we believed the Earth to be flat. Then it was discovered that it is actually a sphere. Then it was discovered to be an oblate sphere (slightly larger around the equator). Even more recently it has been discovered to be a pear-shaped oblate spheroid (wider around the equator as well as the southern hemisphere). The point to take away from this is that all of those conclusions are by definition "wrong", but each one is better than the previous one. Definitive truth is impossible to achieve, but that does not mean that we are incapable of increasing our knowledge of how the universe operates. Theories (such as biological evolution and modern cosmology) are collections of facts which work in concert with one another to provide a larger understanding. They, like other things in science, are not elevated to the level of absolute "truth", but are instead constantly evolving as new evidence is discovered, inching closer and closer to a more accurate understanding of whatever aspect of the universe they address, just as in my example of our understanding of the shape of Earth.

        People like you bore me. You're free to deny reality, but I tend to believe that what allows us to communicate right now is some guy named Maxwelll developed the background of electrodynamics needed to work with electricity. I tend to believe science represents aspects of the real world, which is why we obtain real-world benefits. I tend to believe I'm actually sitting at a computer.

        You can play the 'brain in a vat' game all you like, but even if we're all just in some fake reality, what could we possibly do about it? There are an infinite number of possibilities, and an infinite number of mutually exclusive possibilities too, playing the epistimolgical 'what if' game is nonsense.

        Science produces tangible results. You're free to speculate about that which isn't tangible, but that seems a waste of time and effort. By the way, science also constantly improves, or as Asimov put it in his essay 'relativity of wrong',

        "when people thought the earth was flat, they were wrong. When people thought the earth was spherical, they were wrong. But if you think that thinking the earth is spherical is just as wrong as thinking the earth is flat, then your view is wronger than both of them put together."

      Also I believe there is a Creator, but I'm not talking about the human god that your bible speaks....The word God encloses a lot more. It is He or She. It's just Force, Power, Nature. Forget the God that you find in the bible with long white hair, eyes, nose and mouth, that speaks in thunderbolts and threat to send you to an inexistent hell. You can't describe such Force under human perception. When the bible was written, authors believe the Earth was plane and the center of the universe, and the Sun circulate around her.

        Exploratory thinking is what brought us out of the caves, for lack of a better illustration. Scientific exploration and understanding provides us with the best hope of advancement for our species. Exploration motivates us to dream. Think of how many young people have been motivated to pursue science and technology as a result of the recent Mars landing. Those are the people who will provide the next generation of discoveries for us, the kinds of discoveries that will improve human existence over the next hundred years as much as scientific discoveries did over the last hundred years. We cannot even fathom what that might mean for us. The worst thing we can do at this point it to stop dreaming of what we can achieve, what we can learn about our universe. Big thinking, dreaming, imagining, and discovering are what have led us to this point of understanding. Manufacturing techniques developed originally for applications in space are now used to produce medical equipment. Memory foam, which your arthritic neighbor may appreciate, was developed by NASA for use in space. There are lots of technological spinoffs which occur as a result of exploration. Medical research and advancement are but a single aspect of our portfolio of scientific pursuits, and they are explored just as much or more than any other subject. The theory of relativity, which is vital to GPS and all of its dependents, was validated through cosmology. Are you arguing that we should remain content with the current state of technology and knowledge and merely reserve ourselves to spending our efforts only on making ourselves as comfortable as we can for the moment? I think there are greater things to be had than simply achieving an acceptable level of existence and then ceasing to advance, we are better than that. NASA's budget is an appallingly low one half of one percent of our GDP, while healthcare spending accounts for approximately 18% of GDP, meaning that we spend about 3600% more on healthcare than we do on space exploration. To be honest, that scares me. "The important thing is not to stop questioning." -Einstein

      • God

        Sorry Rob, that's not correct. Culling the old doesn't affect anything in an evolutionary sense as old people have probably already propagated their genes by the time they get old. All culling the old does is allow traffic to move a bit quicker and healthcare costs to be reduced, so while killing off everyone over the age of 65 is good social and economic policy it's a poor eugenics policy.

        But getting rid of the sick is fine so long as they haven't propagated yet, or if they have then a retro-proactive policy of also culling any offspring the infirm may have had would achieve the same result.

    Think upon this. They say this one cluster alone contains "hundreds of thousands of galaxies the size of the Milky Way". The Milky Way, our own galaxy, contains and estimated 200–400 billion stars. It may contain at least as many planets, with an estimated 10 billion of those orbiting in the habitable zone of their parent stars. So take those numbers and times them by a few hundred thousand and you've got this one cluster..... out of countless billions of clusters of galaxies in the know universe. And my dad drove a Ford Galaxy in the 70's. That was a cool car.

      The author states: "It [this cluster] contains hundreds of thousands of galaxies the size of the Milky Way, in addition to dark matter and hot gas."
      Now if the Milky Way contains a trillion solar masses (a low-ball estimate), and the cluster contains 2500 trillion solar masses, then the cluster can have at most, 2500 galaxies the size of the Milky Way - not hundreds of thousands. So the author is probably off by a couple orders of magnitude.

        A "year" as a human definition for a period of time. The universe operates across an axis of time. You can call it years or millenia or gooberjoobers, but the universal clock ticks at the same rate everywhere. Now, if you're referring to the observation of the universe at one point from another point, or observing something where relativistic speeds are involved, then yes - the march of time begins to become murkier for the observer.

        August 16, 2012 at 3:14 am |
      • Sciguy73

        The "Universal Clock" (whatever that is) most certainly does not tick the same everywhere. It depends entirely how fast you're moving, and more importantly in this instance, how strong a gravity field you're experiencing. If you're in a valley on earth, and I'm on a mountain, your clock ticks slower than mine, because you're in a higher gravity field. Go visit a neutron star, and that time difference becomes substantial.

        August 16, 2012 at 5:32 am |

      But you are also a time machine, Vega. You travel through time, although only in one direction and at a (mostly) fixed rate. You don't even need a Flux Capacitor.

      Yes, it is more likely that God made stars than current astrophysics theories, because to say that gas becomes more dense in a vacuum naturally (enough to create a fusion reaction no less. If it were so easy, the iranians would have done it by now) completely contradicts the second law of thermodynamics and boyle's gas laws.

        Sorry, Christian, but gasses condense due to gravity, and gravity occurs naturally. Maybe you're saying that God is gravity.

        What's interesting is that you say something is a bad explanation if it doesn't occur naturally, and I agree. But what that means is that God is a pretty bad explanation since God doesn't occur naturally, by definition.

        Copanut, if you were in a spaceship, in space of course..., with a hole it he window, would you die or would the air condense back into your spaceship? Hmmm... You should go try this out.

        I'm not sure if you are aware of the scientific fact that magnetic forces are far stronger than gravitational forces. Even if gravitational forces brought matter together, the magnetic forces are far too strong for a fusion reaction to happen. That's why we don't initiate a fusion reaction with gravity, we use e massive energy from fission reaction to overcome the magnetic forces at the atomic level..

      • copanut

        Christian, as you say, gravity is weak. My body does has gravity, but far too weak to attract gasses (on the contrary, I've been known to emit gasses, but I digress). But when we are talking about masses of matter the size of a star system the gravity of that matter will result in condensation into larger and larger bodies including, eventually, a star. The increasing volume and density of the accreting mass accelerates the process and past a certain point can ignite nuclear reactions.

        Gravity is weak, but works over vast scales of space. Magnetism is strong, but only works in very close proximity.

      • copanut

        Christian, try this experiment. Hold two small magnets very close to each other. They will snap together. Hold them one inch apart and let go of one. Will it snap to the other magnet or fall to the ground?

        E&M is stronger than gravity, that's true, but it also scales differently. The electromagnetic force, having an inverse square relationship, gets weaker faster than gravity does. That means you get less of an effect the further you go. Now, large masses will become very dense as a result of gravity, since gravity tends to operate on much larger distance scales than the electromagnetic force. As you said, because of the electromagnetic force being stronger, those dense balls of hydrogen will have a problem fusing, because gravity isn't strong enough to keep atomic nuclei together. At least, not for extended periods of time, a random collision might happen here or there, which is exactly the point.

        Physicists don't contest this at all, they are fully aware that gravity is not the force binding the atoms together in fusion, it's just not strong enough. No one claims it is.

        But what about another force? Is there another force that, in dense enviornments, that will be able to counter the repulsive force of electricity and magnatism? It has to be strong, much stronger than electricity and magnatism, because it must ensure that any particle which happens to smash into the nucleus can bind, and in fact it has to be so strong that with atoms like hydrogen, this effect will in fact release energy. You don't want it to barely capture an atom, you want this captured to be the favored lower energy state.

        Do physcists know of a magical force like this? What could possibly be responsible for holding the nucleus of an atom together in the first place, how does fusion work?

        Oh, wait, they DO have that force... it's called (for lack of originality) the nuclear strong force. What happens is these little particles called 'gluons' (physcists don't try to come up with tons of original names) interact on much smaller scales than even the electromagnetic force, so when gravity causes a dense soup, the electromagnetic force prevents it from immediatly undergoing fusion, but the strong nuclear force allows fusion to happen once you've got a dense enough enviornment for SOME particle collisions to happen randomly.

        So, roughly speaking, stars work like this. Hydrogen gets attracted to more hydrogen gas on a large scale, becoming denser and hotter (due to the potential energy from gravity) and the hydrogen begins to ionize. Now, at a certain point, compression begins to stop, because the electromagnetic force prevents further compression of the ionized hydrogen gas. Now, in the core, if the core becomes hot enough from compression, some particles will have enough kinetic energy to overcome the electromagnetic force barrier and protons will collide. The strong nuclear force takes over, and the particles fuse together, releasing energy, making the core hotter and making collisions more likely. This pressure then tends to keep the core of the star from collapsing on itself.

        Now the most interesting things come from when electromagnatism isn't responsible for helping fight against compression... that happens after supernova which generate neutron stars (thanks to neutrons being electrically neutral, the only thing preventing further collapse is pauli exclusion), hypothesized quark-gluon stars (not confirmed), and of course the famous black hole, where compression was so extreme that nothing could prevent it (happens in supernova after incredibly large mass stars die)

        Now I know you might think fusion is impossible, or that astrophyscists are lying to you... but just how much schooling have you had in the subject?

    • Christian

      Additionally, "Astrophysicists are still trying to understand how galaxies got their stars. Gas needs to cool down and become dense in order to form stars, but that process is still an open research question, said Megan Donahue, professor of astronomy at Michigan State University in East Lansing. Only about 10% of the gas in universe is in stars."

      If gas needs to cool down to become denser, how does the fusion reaction start which essentially needs energy (heat, our bombs use a fission reaction). Gas cooling down is the opposite of you need to get a star going. But if it doesn't cool down, it never gets dense enough to start either. So science actually points more toward the likelihood of a created universe than a random one. But of course, you can always ignore scientific facts and believe nothing exploded one day and here we are!

      August 15, 2012 at 8:52 pm |
      • copanut

        You really don't understand the science at all. Start with the claim of violating the laws of thermodynamics. Wrong. I'd suggest to take a real astrophysics course at a real university, or at least do a google search outside of Christian blogs, before babbling nonsense online.

        August 15, 2012 at 8:59 pm |
      • Go Ducks

        Actually Christian the heat comes from the compressing of the gas atoms, mostly hydrogen and helium. As they condense due to gravity they heat up, and as more and more pile on it gets hotter and hotter. Eventually there's enough mass piled on to the star that the temperature at the core, the most compressed region, is hot enough to initiate hydrogen fusion and that is what starts it. Not God.

      They know approximately how far away it is because astronomers have been able to measure the distance to certain stars of a known star type. These star types are all of different sizes and the rate of consumption of fuel at their cores determines how long they survive as stars. Knowing the absolute magnitude (standardized brightness, or albedo) of stars allows them to extrapolate how far away a specific star is from us. It is just an estimation, but it is one based on the laws of physics and direct observation. Once astronomers know how far a star is away the can easily compute how long it will take light to reach us from there.

      That is an interesting question; one I have had also. Why can we see that light from x-billion years ago? Could I look at another part of the sky and see it as it was (x-2)-billion years ago? I don't know enough to answer that. I am guessing though, that our life is so "short" that we have only been able to see a small snapshot (an instance in time) of the universe.

      • James Hawk III

        Well, there's a lot of light coming off galaxies (light is inexpensive to make–Nature makes a lot of photons), and it's very persistent. As long as it's not absorbed by something, or subject to too much red shift, an individual photon can last practically forever.

        Areas with no matter in them don't give off light–so you can't exactly see an area as it was two billion years ago if there was nothing to see in that location. (The quantum theorists in the room will say I'm wrong, and they'd be correct–but the amount of light generated by free-space pair production in low-gradient space-time is so low as to be effectively zero at these scales.) Not only that, the area you specify at a distance of two billion light years away could have something in it now–but we wouldn't know that for two billion more years because the light hasn't gotten here yet.
