Universe's First Objects Possibly Seen

Astronomers, with the handy NASA Spitzer Space Telescope, are definitely on the verge of something huge. The images posted above, taken by the telescope, just might prove to be the very first objects in the universe.

Clustered some 13 billion light-years away, the potential "universe-infants" are 1,000 times as massive as the Sun. The other theory as to what these are is that the objects are early blackholes that consume gas "voraciously and spitting out radiation like crazy as nascent galaxies form."

According to Alexander Kashlinsky, lead author on two reports to be published in the Astrophysical Journal Letters, and member of NASA's Goddard Space Flight Center, "We are pushing our telescopes to the limit and are tantalizingly close to getting a clear picture of the very first collection of objects. Whatever these objects are, they are intrinsically incredibly bright and very different from anything in existence today."

If the cluster of mysterious objects turn out to be composed of stars, then they could be the actual first mini-galaxies. If so, then according to their calculations, each would have a mass that's less than a million suns. Okay, how big is that exactly? Just think, our Milky Way holds about 100 billion suns. The cluster number, that's for each star in there...That's big.

Anyhow, so far, what's making the observation difficult is that they aren't clear-cut. They had to remove light from foreground stars and galaxies so that they could study fluctuations "in what is a relatively diffuse light" (see image above).

 » How can objects be 13 billion light-years away??
The age of our universe is estimated to be about 13.7 billion years. the whole mass of the universe expands from one spot (big bang theory). how can objects be 13 billion light-years away? they must move with almost lightspeed relative to our galaxy (or the earth). this is not possible. or i´m thinking wrong?

Dûh, offcourse you're thinking wrong. The big bang is just a theory, it's not really the way it went

ok, then the big bang theory is obsolete. but most scientists still support this theory. why?

Just because the objects are 13 billion light years away..that dont mean that they are that old.
The distance of an object had nothing to do with the "age" of the same object.Is just saying that it will take 13 B lightyears to get to them..
Like saying that it would take me 3 years to walk aroun the planet......that dont mean that the planet is 3 years old....its just the space between that takes that much time....

Get it?

no, your argument makes no sense whatsoever.
sry.

 » no i don´t get it
you say: "Is just saying that it will take 13 B lightyears to get to them" yes, thats the point. the light from these objects was 13 B lightyears on its way from there to earth. light only moves with lightspeed not faster ;). so the objects must be there 13 B years ago. right?
