Discussion: Wallpaper: New Hubble Deep Field

[Fraser]

SUMMARY: Here's a 1024x768 desktop wallpaper of a new deep field survey taken by the Hubble Space Telescope. In case you get tired of counting, there are 10,000 galaxies in this picture - the farthest are almost 13 billion light-years away. This photograph required 800 separate images taken by Hubble on 400 orbits around the Earth between Sept. 24, 2003 and Jan. 16, 2004.

What do you think about this story? Post your comments below.

I can't tell the scale by looking.

It would be interesting to see this side by side with the old deep-field image set with equal milli-arc-seconds per inch, so as to see the improved resolution and optical depth.

I would be interested in the galaxy distribution, there should be a significant increase in young galaxies, or what is called oddball galaxies (aka peculiar galaxies). This survey, does it include spectra as well?

Cheers.

Sorry, didn't read the article through to the end, the "grism" did all that, so now it's waiting for the results!
Cheers.

Posted this elsewhere, but it really belongs here:

Interesting newsflash on CNN this morning. The report showed the most recent deep-space image aquired by Hubble with an explanation that it is the deepest view yet obtained.

The story then went on to say that this could be the last such picture obtained given NASA's decision not to send a final refurbishing mission to the Hubble.

Seems to me that the STSI is taking their case directly to the American public
Good for them I say!

Heh! :P

Hubble Ultra Deep Field Discoveries Support a Firework Universe Made of 3D-spirally Folding and Unfolding Sources of Interaction

"Galaxies evolved so quickly in the universe that their most important changes happened within a billion years of the big bang. "Where the HDFs showed galaxies when they were youngsters, the HUDF reveals them as toddlers, enmeshed in a period of rapid developmental changes," Stiavelli says [1]". This latest finding from the Hubble Ultra Deep Field (HUDF) observations is consistent with Eugene Savov's "firework universe" in which every body was suddenly ejected from the depths of its 3D-spiral source [2]. The just born "firework universe" was made of bright blue stars, which orbit around their sources the galactic nuclei. The latter moved around their sources and so on. Everybody moves around the source of the universe, which spawn smaller sources of interaction from its structure. They did the same and so on the interaction unfolded to smaller scales. Hence the galaxies, stars, planets and the planetary like moons are like very "huge atoms" [2]. The insides of the "huge atoms" are seen as visible matter because the found 3D-spiral sources of unifying interaction move faster inward and so become dense enough to reflect or emit light [2]. The HUDF discovery is just another proof of the "firework universe", made of unfolding huge atoms, i.e. 3D-spiral sources of unifying interaction that are the building blocks of matter. The code of the universe is a 3D-spiral and it is in each of its bits [2]. Matter is not made of elementary particles but of unfolding to smaller scales 3D-spiral sources of all-building interaction [2].

Thanks!!!

I have some queries:

If the galaxies observed are 13 billion light years or more away from us, does this mean that the particles in our galaxy and those close by have been moving away from these young galaxies at a speed close to the speed of light for the age of thwe universe - assuming the age of the universe is approx 13.7 billion years.

There must be other galaxies further away from these young galaxies than ourselves - such that the distance would exceed that possible in 13.7 billion years assuming the speed of light as upper boundary.

Is the density of these young galaxies significantly greater - bearing in mind the smaller universe at that age?

Are the shapes observed affected by speeds close to light - if this is the case.

Can anyone help me?

I was wondering... If the universe is about 13.7 billion years old.. and Hubble sees upto 13 billion years away... Cant it see farther?? What will we see?? Sorry if this sounds amateur.. I'm into astronomy but the physics just gets my mind all wobbly. And Frasier.. Thank you for Universe Today!

You do not need to assume constant speed of light to understand
the universe. Assumptions drive you away from the core of the matter.
Why do you expect God to care about our assumptions?

Ishtaar, light moves at the speed of... well, light. Since the Universe is only 13.7 billion years old, that means we can only see objects which are up to 13.7 billion light-years away. Remember that anything we see in space is actually being seen how it looked in the past, when the light was generated. There are probably galaxies 30 billion light-years away, but we can't see them because it would take longer than the Universe has been around for the light to reach us.

Oh, and thanks for the kind words. :-)

More importantly, the age we determine for an object is some percentage of the age of the universe. To keep articles short and on-topic, writers translate this percentage to an age in years using the presumed age of 13.7 billion years. Most scientists agree that this age is probably pretty close to the actual age, but if it suddenly were discovered to be ten times that old [not likely], things seen at z=7 would be called 8 billion years old, not 800 million years old.

Does that make sense to anyone? I'm afraid you completely lost me here Fraser.

Cheers.

I think he means that if during the big bang, the universe was created in a spherical shape- exploding in all directions- then there would be galaxies beyond the center "big bang" point. Or maybe theres galixies in the "other direction" (because the universe is still expanding) and we cant see them yet, I'm not sure. This is very confusing...

[Guest_guest]

The HUDF findings suggest lumpy universe beginning.

How can you push the Big Bang in lumpy structure build-up so soon???

It seems you may better consider some alternatives.
