A Supernova In Red/Blue Plaid, Please 172

Snotnose writes "The New York Times is reporting that scientists have found a a supernova factory . From the article, scientists estimated that the cluster alone, which contains up to a million stars, probably produces a supernova once every two years. That is a rate 50 times higher than usual in entire galaxies. Stars explode in Earth's home galaxy, the Milky Way, only once in a century.. Sounds pretty awesome. "

        Actually, when the gas goes by the pressure goes from zero to something less than zero. The supernova does indeed have a sound, and it probably is some kind of "boom" full of turbulent white noise. Of course, that sound never reaches us in any meaningful way, and if it did we'd probably all be dead.

        IIRC, one of the NASA probes once recorded the sound caused by interractions in the rarified gas associated with Jupiter's intense magnetic fields.

        So yes, there are indeed acoustic waves in space. It's just that they aren't like the atmospheric waves we are used to. That doesn't mean they aren't sound. You can't hear very well under water, but dolphins can. You wouldn't say that the ocean is silent just because humans have lousy hearing there. Likewise, we shouldn't say that space is silent just because the pressure is extremely low and we'd immediately die there.

        That said, given that space is almost a vacuum, you can't produce sound in the usual manner. You have to introduce a gas into space that allows sound to propogate, and a supernova does just that.

          IAAA (I Am An Astrophysicist) and
          Actually, when the gas goes by the pressure goes from zero to something less than zero.

          is flat-out wrong. Negative pressures do show up in certain exotic bits of physics, yes, but the interstellar medium isn't one of them.

          It's only an approximation to say that the pressure in space is zero. Very, very low, sure, but pressure will be some small positive number anywhere there exists an appreciable amount of gas (which is pretty much everywhere, actually). The pressure in the local ISM is something like 10e-19 bars, give or take a bit. As far as human hearing goes, that's certainly low enough to be effectively zero, but pressure waves can and do still exist, at positive but low pressures, albeit at frequencies and volumes far far below anything we could detect by ear.

          In fact, it's very useful to think of the intersteller medium as a sort of atmosphere surrounding the galaxy, complete with high and low pressure zones resulting from differential heating, winds and superwinds blowing between those regions, "weather" of a sort along the boundaries between regions of different temperatures, and so on. For more detail (a *lot* more detail) check out Spitzer's Physical Processes in the Interstellar Medium or Osterbrock's Astrophysics of Gaseous Nebulae and Active Galactic Nuclei, hopefully available at your local university library.

          • read my comment above. It's not 'flat out wrong', although the english may be a bit awkward.

        I think that there will probably be a peak in the number of supernovaes per year (if it already hasn't happened). Over time, though, what will happen is that galaxies will age, resulting in fewer, more longer-lived stars (and possibly black holes). In other words, give it several hundred billion years, and most of what's left of the universe will be populated by very small red dwarves and super-dense objects. A few trillio

    From what I remember in Astronomy class, the only known way blackholes are known to form are after a supernova explosion. This can make for an interesting study on blackholes.

      http://plabpc.csustan.edu/astro/stars/holes.htm

      This page explains the link between Black holes & Supernovas...

      When stars of very large mass explode in a supernova, they leave behind a core which is so massive (greater than about 3 solar masses) that it cannot be stabilized against gravitational collapse by an known means, not even neutron degeneracy. Such a core is detined to collapse indefinitely until it forms a black hole, and object so dense that nothing can escape its gravitational pull, ot even light.

      I don't think this is accurate.

      Certainly it is a reasonable hypothesis that a very massive star might create a black hole when it supernovas. I don't know what the latest computer models say about it, nor do I know how reliable those models are believed to be - this stuff is hard to model right.

      Merging neutron stars are also likely to form black holes, and a neutron start that was accreting mass from a companion star could also.

      Our best evidence for black holes is for supermassive ones at the centers of galaxies. These would be the result of a long period of growth by swallowing stars. We can't know now where the original 'seed' black hole came from, but the vast majority of its mass did not come from a supernova.

    So I'm seeing lots of funny stuff, but no serious comments. Okay, we knew about supernovae, and we knew that where there is star formation, sooner or later there will be star death and supernovae as well. No freaking big deal, right?

    The surprise here is the rate of supernovae going off in that tiny volume. One cluster, one million stars, and a supernova every two years. In our galaxy, we're still waiting for one since the days of Galileo and Tycho, probably an average rate of one every century or so. And this is with Billions and Billions (TM) of stars in our galaxy!

    So that is a pretty big surprise. And it is a VLBA result: very cool. (The standard analogy for the VLBA resolution is the ability to pick out Roosevelt's eye on a dime held up in LA while you are standing in New York...)

    • Locally, the expansion of the universe can be countered by gravity. Just like the stars in our galaxy are held together by gravity, galaxies form clusters in which the velocities are not what you would expect from the expansion of the universe alone.

As they continue to go outwards the space between them would increase, not decrease. Now, I know the debate about "are we expanding forever or not" but can someone in a nut shell explain to me what would cause a galaxy to alter trajectory so much as to collide with another - especially after this much time from the big bang? Thanks.

      The universe did not have a "source point" where all matter spewed from in the big bang. Instead, its space itself that expands and carries everything along with it in more or less an even pace.

      Use a balloon as an analogy. Take a balloon before blowing it up and use a felt-tip marker to put lots of dots on it. The dots represent galaxies and the balloon the fabric of space. Now blow up the balloon. All the dots recede from each other evenly, even though there is no source point. While you may think of the center of the balloon as a source point, it isn't really, because it exists outside the normal 2 dimensions of the surface of the balloon.

      Increase all the dimensions by 1 and you have the situation you do in the universe. Space itself is expanding. Thus since everything has not been thrown out from a source point, there is plenty of time for gravity to pull together galaxies over great distances. Gravity is the weakest of the four fundamental forces but its effect stretches over the longest distance.

      Also, when galaxies collide, in most cases there is very little star-to-star collisions, since there is so much empty space between the individual stars. What happens is the interplay of gravity between the stars warps the overall structure of the galaxy, which can have the effect of either stripping it of starmaking material and thus lead to the slow death of the galaxy, or concentrating it and leading to bursts of stellar births (and deaths, if the generated stars are very high mass and burn throught their hydrogen quickly).

      Hope this helps a little.

    Sounds pretty awesome.

    I was going to say, "Sounds like a nice place to visit, but I wouldn't want to live there." Then I realized that the frequent huge doses of ionizing radiation would probably wreak havoc on television reception and other things. So maybe it's not even a nice place to visit. And I'm just sure I couldn't live there for very long.

    Anyone remember that episode of Andromeda where some evil dictator acquires weapons of mass destruction that can take out entire stars? Maybe that's what's going on there, they're just testing & stuff...

    does this remind anyone of conway's game of life? eg, how first they discovered "persistent" creatures, like:

    ***
    *
    *

    and then later discovered factories that produced such creatures? of course, that leads into "what about factories that produce these 'supernova factories'? where do they get their materials from? ...perhaps from the cast-off remains of exploded supernovae? if so, have we discovered a stellar ecosystem? no doubt others have considered this...

    A Supernova In Red/Blue Plaid, Please
    Did anyone else read this and immediately parse this as something out of Vernor Vinge's A Deepness in the Sky [amazon.com]?

    The book describes a species of aliens who see in many more colors than we do. One color, commonly found in sunsets, is translated into English as "plaid."

    If you haven't read it already, I highly recommend it. It's arguably the best book by one of the brightest authors out there. He's the only author where I can't find anything to quibble about concerning his computer science. [Sample Chapter] [tor.com]

    First off the space.com story alternated between calling the galaxy Arp 229 and Arp 299 which totally confused my astronomer self.

    BUT. . .Arp 299 is one of the galaxies calssified as a starburst galaxy, meaning we see lots of star formation going on in Arp 299. People saw how much star formation with ISO [vilspa.esa.es] and we'll be looking at it with SIRTF [caltech.edu] after we launch. It's thought that supernovae can trigger star formation by the shocks from the explosion disturbing the gas clouds and making them unstable. Of course the multiwavelength data is needed to test this theory and this radio data combined with the optical and infrared will be a good first start. . . .

    I'm probably picking nits here, but doesn't it sound odd to speak of a "supernova factory"? It makes as much sense as a moldy bread factory or a worn tire factory. A supernova is the death of a star after a long life, it makes no sense to suggest that this cluster is stamping 'em out. Better to say that at one time this was a star factory, producing shiny new stars which are/were dying at relatively the same time.
  • Stars explode in Earth's home galaxy, the Milky Way, only once in a century.

    I thought that was common knowledge.
  • Galactic merging can be tied to an increase in the rate of supernova formation, not through actual mass accretion from stars between galaxies, as galaxies usually just past right through each other when they merge, but rather through gravitational interactions that somehow destabilize binary systems that would have previously not have resulted in a supernova.

    For instance, gravitational tides resulting from merging galaxies could change a distant circular orbit between two stars, one a white dwarf, the oth

    As usual, the Astronomy Picture Of the Day [nasa.gov] has a very nice picture and explination of this.

    And as a bonus, today's APOD [nasa.gov] is one of the kewlest sunset pictures I've ever seen.

  • Just to be anal because I feel like it today, a plaid [reconstruc...istory.com] is a sort of sash come toga wrapped around the upper body in traditional highland dress. It is a garment not a cloth pattern. The family of cloth patterns used by the highland clans is called tartan [50megs.com]. To quote this page [infokey.com]:

    Originally, the Scottish Tartan was a distinction of rank or position. It was not identified by weave but by the number of colours in the weave. If only one colour was used it depicted a servant, two, a farmer rank, three, an officer

It's a naive, domestic operating system without any breeding, but I think you'll be amused by its presumption.
