'Green' Galaxy Recycles Gas, Supercharges Star Birth 36

astroengine writes "In a galaxy, far, far away (6 billion light-years away to be precise), the most efficient star 'factory' has been discovered. Called SDSSJ1506+54, this galaxy generates a huge quantity of infrared radiation, the majority being generated by a compact region at its core. NASA's Wide-field Infrared Survey Explorer first spotted the galactic oddity and Hubble confirmed the maelstrom of stellar birthing near its core. But the most amazing thing? This galaxy is the 'greenest' factory yet discovered — it uses 100 percent of all the available hydrogen to supply the protostars, leaving no waste. 'This galaxy is remarkably efficient,' said lead scientist Jim Geach of McGill University in a NASA news release. 'It's converting its gas supply into new stars at the maximum rate thought possible.'"

    When I read the "100%" I had to go to TFA and read the whole thing ...

    The Nasa article ( http://www.jpl.nasa.gov/news/news.php?release=2013-144 [nasa.gov] ) says " ... with almost 100-percent efficiency " but the submit uses the hyperbole "... it uses 100 percent of all the available hydrogen to supply the protostars, leaving no waste ."

      Imagine if it were as efficient as Slashdot:
      The SlashStar Galaxy would recycle things so efficiently that it wouldn't need to produce any light of its own -- feeding only from the energy of other nearby systems. It would sometimes appear to have two of the same starticles in the same region, not due to gravitational lensing, but due to not caring enough about how it looks enough to even notice it had already processed the same material earlier. Every entity responsible for the formation of the SlashStar Galaxy itself would be either an invisible blacktroll of negativity or a nebulous "dark matter" hidden in its shadowy basements. Any direct observation would be near worthless without extensive research to discern what the measurements actually meant, but spending time on such a thing would be frowned upon -- Merely seeing what system it passed in front of next being the prime interest of the scientific community. Though you could not observe the individual components that make up the SlashStar Galaxy, you could measure their collective effect on their surroundings: Occasionally the maelstrom of minutia would align in a catastrophic conjunction causing a great funnel of forces that eject great streams of individual energetic particles, obliterating any unfortunate system in its path -- The SlashStar effect.

    Just how precise are we talking here, 6 billion sounds like a really round number.

    It we be very cool (and intimidating as hell) if it turns out that galaxy has been engineered this way by some advanced alien entity. I guess we'll know in a few thens of millions of years when it does (or doesn't) turn elliptical.

      I was wandering exactly same thing while reading it, and that would be Type III civilization on Kardashev scale.

        Careful. Around here, talk like that can get you labeled as a "crazy creationist" or a "sky god worshiper". Of course compared to our tech, being able to create something like that seems pretty deserving of the title "sky god".

  • I am not sure I would describe this as "Green". Using up all available resources in one massive burst, leaving nothing for future generations. Efficient, yea - in the way a nuclear bomb is efficient. But basically a cheap headline to draw attention to what is, yes, an interesting bit of astronomy.

    • If a nuclear bomb were 100% efficient it would have no fallout. So that's kind of green. A dirty bomb doesn't undergo nuclear chain reaction at all, so it has maximum amount of fallout that makes dirty.

  • I thought the most efficient star factory was in Hollywood, where they efficiently turn no-talent chumps into overnight sensations using only skimpy clothes, hype and recycled plotlines, leaving behind only a trail of burned-out losers that the tabloids follow around for the remainder of their pathetic lines to show you how fat and out of shape they've gotten.

    But this does seem better.

  • "This galaxy is the 'greenest' factory yet discovered... ...leaving no waste."

    Green? Waste?

    I keep seeing humans applying these fuzzy concepts with apparent emotional significance to inanimate objects and natural processes. What's green about turning hydrogen into stars? Green is suppose to be good, right? Is loose hydrogen bad? Don't stars use fusion to produce radiation? Don't the same people that talk about 'green' incessantly also speak badly of nuclear fusion and radiation? Isn't that called toxi

  • "In a galaxy, far, far away (6 billion light-years away to be precise)..."

    Just pointing out that if we're observing it it must've happened 6 billion years ago as well. If you're gonna go for the Star Wars quote, might as well go all the way.
