Hubble vs. Webb - How Far Back Will They See?

Roland Piquepaille writes "According to Forbes, reporting in "Peering Back At The Universe's Past," space telescopes are really acting as time machines. They can watch objects which are so far from us that light has taken billions of years before reaching their mirrors. The Hubble telescope is able to look at events that took place 13.3 billion light-years ago. But the James E. Webb space telescope, currently under construction, and scheduled to be launched in 2011, will be able to see even further and catch phenomena which happened 13.5 billion light-years ago. The astronomers think the Webb telescope might even be able to see up to 13.7 billion light-years ago, when our universe was just 200 or 300 million years old. We are used to see fantastic images from Hubble, without paying too much attention to the characteristics of the telescope itself. So here is a thorough comparison between the two space telescopes."

    13.7 / 13.3 = 1,030075188 => 0.03 % performance increase with the new, latest, more expensive system.

    Nahh, I'll maybe void my warranty, but I'll just increase the fsb of my old Hubble...

    Anyone has tips on deep space overclocking ?

    As I'm sure everyone will be quick to point out, lightyears isn't a measure of time, rather of distance.

    Dear Sir,

    Some of us prefer the universe the way it is, more mature and filled out. I think its disgusting that these perverts want to spend so much money to ogle at the universe when it was a young hottie.
    No doubt they are also hoping to get a glimpse of some of the banging the universe got up to in the exuberance of youth.

    Shame on you all I say.

    Yours etc.

    maybe this will help:

    it takes light from the sun about 8 minutes to reach our planet.

    this means that the sun could have blown up 7 minutes ago, but it will still appear normal for about another minute or so.

    then you will be toast.
