So, on the one hand we have Nasa and the Hubble telescope extreme make-over, promising images as far as 500 years after the Big Bang. Sorry, link in french.

On the other hand, we have the ESA and Planck & Herschel program, promising images down to 380 000 years after the Big Bang. Sorry, link in french......again

While I rejoice upon Hubble's newfound life span, I kinda wonder about the real limits of our "vision". Can we really go back farther than the 380 000 limit? It seems (although I might be mistaken) that this particular time would be the moment when light "separated" from the gooey mumbo-jumbo and thus is the limit to what we can "see".

But Nasa claims to scope down to 500 years Post Big Bang.

Utopia? Mistake from the reporter? Blatant propaganda?

A better way to think of it is this.  Things were so energetic, noisy, close together, etc. that light could not travel very far.  Physicists consider the universe pre~380,000 years old to be opaque.  The reporter discussing how far back the Hubble could look must have heard wrong.

Oh.  That wasn't what you meant?

Ok, thanks, that's what I was hoping for.

Carlson: yeah, kinda...:D

Sorry. The headline to your 2nd link reads:

How disappointing.  When I saw the title "Hubble vs. Planck & Herschel", I thought you were talking about a cage fight.

By the way, Fritz Zwicky could have kicked all of their asses.
