Hubble Snaps Farthest / Oldest Galaxy
starannihilator writes "Astronomers use gravitational lensing, a magnifying effect caused by the gravity / mass of galaxies, to capture images of the farthest / oldest galaxy known - from when the universe was just 750 million years old. Stories from the BBC,

Hubble needs this sort of thing to keep it serviced. This is very interesting and in my mind at least partially justifies Hubble.
vampirical
I can't recall how many hundreds of times I have seen Hubble in the headlines over the last few years. The waiting list for Hubble time is insane, and the science has been among the best that NASA has ever done.
It's amazing to me that this "it's too risky" reasoning for the cancellation of the repair missions to Hubble is still being floated.
It's franky disappointing to me as American that we are such a nation of wimps now. I personally think it's more of a risk to send people to the space station in regards to the scientific return.
While I have seen hundreds of "discovered by Hubble this week" I have not seen one discovery in the news come from the station. It's usually fighting with the Russians or announcing it's going to cost ten times more than we thought to do one twentieth the science.
Yes, I am off-topic. But I'm mad as hell and not going to take it anymore!
WHY are we just letting the Hubble die again?
.. lets study it to learn more about the origins of the galaxy! Oh, we can't lease any more time on the Hubble because we're junking it remember?.
Oh yeah, thats right, NASA says that it costs too much to maintain, and it's getting close to its estimated end of life date.
Guess we better junk it because it seems we aren't getting any good science out of it. Whats that? oldest known galaxy huh? Cool!
Once again, I think NASA really needs to learn a very old saying that you don't junk something until you have a replacement. When the JWT is operational and snug in its lagrange point, then we can talk about whether or not to scrap the Hubble. Until then, I think its worth perhaps *outsourcing* a maintinence mission to another country (or private company) who thinks they can get the job done.
Who says we *have* to use the shuttle? Or is there something I am missing about the shuttle being the only craft that can work on the Hubble?
Then again, I can't think of anyone else that can get there at the moment either. And if they can, I suppose they would probably be more apt to put their own agenda's ahead of a NASA maintinence mission.
Oh well.

So, we can apparently see [the light from] something 13 billion light years away, and find something 750 million years old, meaning we can see about 95% of the life of the universe.
How long will it be before we can get to the point where the whole universe was invisible?
Ask me about repetitive DNA
Don't the astronauts have to do EVA anyway while doing the Hubble service ? I mean, they should be able to spare 10mins for checking the shuttle... No reason for a second EVA.
In typical cya fashion, O'Keefe called on Harold Gehman, who led the Columbia accident inquiry, to review the decision. It's a bit of neener neener on O'Keefe's part because Gehman's commission nailed NASA for sloppy safety management policies.
What O'Keefe is saying to Gehman is "Look you SOB - you try running an agency that's being pulled 20 different ways and see if you don't start cutting corners."
Problem for O'Keefe is that there are plenty of ideas on how to both service Hubble and adhere to the Gehman's commission's advice. Not surprisingly, NASA management choses to ignore its engineers instead of listen.
Nasa will be well rid of Mr. O'Keefe when he leaves. Next time, maybe the powers that be will appoint someone with an engineering background to run the agency.
