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."

    It is official; Netcraft confirms: CSLib is dying

    One more crippling bombshell hit the already beleaguered CSLib community when Fnord confirmed that CSLib sourcing has dropped yet again, now down to less than a fraction of 1 percent of all logins. Coming on the heels of a recent Netcraft survey which plainly states that CSLib has lost more sourcers, this news serves to reinforce what we've known all along. CSLib is collapsing in complete disarray, as fittingly exemplified by falling dead during recent SEG projects.

    You don't need to be in helpdesk to predict CSLib's future. The hand writing is on the wall: CSLib faces a bleak future. In fact there won't be any future at all for CSLib because CSLib is dying. Things are looking very bad for CSLib. As many of us are already aware, CSLib continues to lose market share. Red ink flows like a river of blood.

    CSLMan is the most endangered of them all, having lost 100% of its core developers. The sudden and unpleasant departures of long time CSLib developers Alan Fnord and Andrew Fnordells only serve to underscore the point more clearly. There can no longer be any doubt: CSLib is dying.

    Let's keep to the facts and look at the numbers.

    CSLib leader Goldsmith states that there are 2 users of CSLib. How many users of Windows are there? Let's see. The number of CSLib versus Windows posts on the Wiki is roughly in ratio of 1 to 5. Therefore there are about 2*5 = 10 Windows users.

    Due to the troubles of Liberator, Deletion of /usr/cslib/bin and so on, CSLib went out of service and was taken over by a small Perl script. Now Perl is also dead, its corpse turned over to yet another charnel house.

    All major surveys show that CSLib has steadily declined in market share. CSLib is very sick and its long term survival prospects are very dim. If CSLib is to survive at all it will be among Geeky dilettante dabblers. CSLib continues to decay. Nothing short of a miracle could save it at this point in time. For all practical purposes, CSLib is dead.

    Fact: CSLib is dying
