A Tiny Galaxy is Born 36

phlack writes "New images from the Hubble Telescope show a new galaxy (only 68 million light years away) is in the stages of being formed, despite its neighbors (such as us) having already existed for billions of years. This can give astronomers new insight into the sgates of galaxy formation. Information can be found at the hubble telescope site, as well as ScienceDaily."

    Uh, this galaxy was new 68 million years ago, its probably formed by now, /.: old news, stuff that mattered.

      Given that galaxies take hundreds of millions of years to form -- the article describes this one as about 100 million years old and still in the early stages of formation -- I doubt that the galaxy has formed yet.

      Wouldn't that be "matter getting stuffed"?

      Actually, the point of the story is that this is "new". Most of the galaxies we see are billions of years old. To see one forming only 68 million years ago is unusual.

      Of course, the galaxy was discovered 20 years ago, so even that "news" is "olds".

      My favorite quote from the article is this one: "the young system sits in a region of comparatively empty space known as a void".
      Well, yes...

    • You have a point, albeit a small one. :) It doesn't really matter if it has formed now or what, what does matter is that the light is finally reaching us, therefor showing us it is being formed. We can continue to watch this stream of light and see it being formed as well as learning how it formed EVEN THOUGH (as you said) it has probably already been formed. It's not like we were planning to send out a probe to watch it develop.
    • Interesting thought, and a prevalent one. However, I don't believe it is accurate. According to Feynman in his lecture on space and time, now is a relative term. Since, in Einstein's theories, nothing can travel faster than light, the now of the universe is what we can view now. Therefore the galaxy is forming now. Perhaps someone with a better grasp can clarify, but I believe that is the basic position.

        Sounds like limiting "the universe" to "the subjective universe." Or in other worde: sure, from a standpoint of how-much-plank-time-has-passed-since -the-time-of-creation that galaxy formed 68 million years ago--but as far as WE care, it's just forming now, since it took 68 million years for the effects of its creation to get here.

        OUR now is limited to what we can percieve--and it's a rather complex perspective, really. However, the "real now" keeps on going at the same rate everywhere as it does here--but the further you get away, the longer possible causality takes to sync between you and us.

    Right, all we have to do is monitor it for a few hundred million years and we'll have the whole story!! :)

      Wait! You're forgetting the DMCA. Those scientists better stop researching that galaxy. After all, it's illegal to reverse engineer galaxy-formation.

      You think you're kidding, but why is this such a bad idea? Why shouldn't we be making an effort to plan extremely long term research projects? Maybe millions of years is a bit extreme, but how about centuries? Or even decades? What can we get started on?

      Humanity doesn't shy away from engineering projects that will require decades [ita-aites.org] or even longer [wcr.ab.ca]. We have run informal experiments [uq.edu.au] on these timescales, as well.

      Why not plan for the future? Leave a legacy of science to future generations. Even if the original purpose of an experiment is superceded, the data collected can be valuable in ways we can't imagine. Let tomorrow's data miners unlock the secrets of the universe, instead of just developing new techniques to sell me crap.

  • Oh, it's sooooo cute!
  • ...astronomers honestly don't know how galaxies form! They have many ideas, of course, but it remains one of the least understood things about modern astronomy. A scientist on space.com said that since we can see galaxies at different stages of evolution, it's sort of like being able to see frogs and tadpoles, and then having to figure out how the rest works on your own... ;)
