    Newfound Galaxy Leaves Scientists Star-Struck

    Astronomers are dumbfounded by a recent NASA discovery: a rare star baby-making machine.

    Scientists used NASA Telescopes to spot the star factory, looking at measurements 12.3 billion light-years away.

    That's reaching back to a time when the universe was only 1.3 billion years old (the common understanding is that the universe is approximately 13.7 billion years old today).

    The team reports the newly found galaxy is pumping out approximately 4,000 stars per year, putting our own galaxy to shame, with its productive output of a mere 10 stars per year.

    This finding debases current theories about star-formation; it requires us to rethink the idea that stars are built up over time, slowly absorbing tiny pieces of galaxies. Instead, it seems stars are bursting onto the galactic scene in one big bang.

    12.3 BILLION light years

    The "Gee Whiz !" attitude of this article ignores the significance of the fact that "When we look this deeply into space, we are seeing a ghostly image out of the distant past......" The newly-discovered galaxy WAS pumping out 4000 stars per year, 12,300,000,000 YEARS AGO. We have no way of knowing what it is doing now.

    Neither do we know the rate of star production in our own galaxy at that time. Insmuch as ours is a very large galaxy, it may very well have been producing many more than 4000 new stars per year at that time in the remote past. The present low rate of star production in our glaxy has an obvious explanatioin. It has run out of material.

    What we are seeing is probably a very young and "fertile" galaxy, much younger in actual number of years than ours is today. The important question raised by this observation is : where from was this ancient galaxy obtaining the material from which to produce all of those stars ? If it were an Irregular I galaxy, embedded in absorbing hydrogen and dust the source of material would be obvious.

    However, this galaxy appears to be a barred spiral . If so, it is comparable to or less in mass than our own galaxy which is a giant spiral. It shows no excess nebulosity which would betoken the presence in it of hydrogen and dust not yet incorporated into stars. So, where is the star-forming material ?
