Hubble Goes to the eXtreme to Assemble Farthest-Ever View of the Universe
NASA ^ | September 26, 2012 | Staff

Posted on 09/26/2012 7:22:19 PM PDT by lbryce

Like photographers assembling a portfolio of best shots, astronomers have assembled a new, improved portrait of mankind's deepest-ever view of the universe.

Called the eXtreme Deep Field, or XDF, the photo was assembled by combining 10 years of NASA Hubble Space Telescope photographs taken of a patch of sky at the center of the original Hubble Ultra Deep Field. The XDF is a small fraction of the angular diameter of the full moon.

The Hubble Ultra Deep Field is an image of a small area of space in the constellation Fornax, created using Hubble Space Telescope data from 2003 and 2004. By collecting faint light over many hours of observation, it revealed thousands of galaxies, both nearby and very distant, making it the deepest image of the universe ever taken at that time.

The new full-color XDF image is even more sensitive, and contains about 5,500 galaxies even within its smaller field of view. The faintest galaxies are one ten-billionth the brightness of what the human eye can see.

I believe you to be correct. There undoubtedly are countless objects or particles and our knowledge is infinitely incomplete. If we still had a manned space program a good place to gain knowledge would be in our own or God’s solar system of which all of us are a part. Smokin’ Joe was correct ... Mars ... we should have been there, done that and gone on to the next task (imho). Most everything learned or discovered was during the race to the moon. To open up new avenues of learning and discovery one must reach for the stars. I truly believe this. No wonder zer0 shut most of the learning and discovery down. zer0 is quite successful in creating a return of zer0.

If it were infinite, it would seem to imply it’s always been there. That there was no beginning.

As in the infinity of God. No beginning, no end. The thing is mankind is limited to what the Will of God is. Though make no mistake the Will of God is good and may good come to mankind is God's desire. That Will of God thing makes one humble when viewing the vastness of creation where mankind (the mankind we know) sits on one lone planet, only to have mankind's search for God's Will be unknown, yet knowing it is good and God's love is infinite because of the written word. Have gone off on a tangent. Loved all your contributions to this conversation. They were good.

Of course we have been there with numerous *unmanned* spacecraft.

Launches to Mars:

1960s, 13 [launches]
1970s, 11
1980s, 2
1990s, 8
2000s, 8
2010s, 2

Six trillion miles *shakes head* it is hard to get your head around that distance..!

Imagine Obama laying two dollars and 66 cents of our nation's debt on each mile...

Problem is mankind can only truly discover if there. Robots are good but insufficient with the calculation compiled by a human. Lenses and robots sometimes go right by an object and that object may hold a key. Mankind is guilty of doing the same, but not to degree mankind is limited by counting on a robot to do the job, when mankind may see or sense something (if there) the human on Earth may tell the robot to miss because back here on Earth the object appears uninteresting. Too many variables relating to being there verses being here.

It would be an extremely dangerous and complex mission...

There are several key challenges that a human mission to Mars must overcome:

  1. physical effects of Health threat from exposure to high-energy cosmic rays and other ionizing radiation.[3][4]
  2. physical effects of a prolonged low-gravity environment, including eyesight loss.[5][6][7]
  3. psychological effects of isolation from Earth.
  4. psychological effects of lack of community due to lack of real-time connections with Earth.
  5. social effects of several humans living under crowded conditions for over one Earth year.
  6. inaccessibility of terrestrial medical facilities.

Some of these issues were estimated statistically in the HUMEX study.[8] Ehlmann and others have reviewed political and economic concerns, as well as technological and biological feasibility aspects.[9]

While fuel for roundtrip travel could be a challenge, methane and oxygen can be produced utilizing Martian H2O (preferably as water ice instead of chemically bound water) and atmospheric CO2 with mature technology.[10]

Yes, but isn’t that like an Amoeba taking a look at us and saying we reminded it of a proton? LOL

We sure are insignificant in the overall scheme of things.

Thankfully, God doesn’t see it that way.

you are correct. There are many challenges to overcome. Once mankind shies away from a challenge, mankind ceases being productive. To learn one must be productive and be there. Our leadership in D.C. has forgotten about productivity and instead is relying on robots to explore. Heck, D.C. probably would be happier if there were only robots, no humans. Though sometimes robots revolt also, or so a movie once said. Thinking of the Terminator series makes me smile.

Very interesting observation. Thanks.

The mind boggles even more...

I agree. The creator of all that, sent His son to die for you, I, and anyone else who accepts the sacrifice, and does what God asks.

It boggles the mind.

Is that a photograph of how the universe looks now, at this time, or is it a photograph of how the universe looked millions of years ago?

The Obumanists in DC are deliberately falling back on various NASA projects because they're trying to help our enemies in Russia and China catch up or surpass us. There are lots of military implications involved in these projects. Obama is the Saboteur-in-Chief on national defense.

Hey, look at that. Every time they say they've found "The End of Everything"... It turns out there is more "there" out there.

Humans suffer from a kind of delusion when you start scaling up that magnitude. This is evident in both cosmology and in discussing our National debt...

Very interesting observation.

I should have stressed that everything else in that eXtreme Deep Field image is a galaxy or proto-galaxy (over 5,000 of them within a patch of sky that can be blocked out by a grain of sand held at arm's length).

Dittos ... the liberal mind is the mind of a robot, completely and absolutely programed with no common sense whatsoever. D.C. leadership likes that type of person, while spitting on the individual. Strange. It is almost like the Borg invaded.

If it were infinite,

In thinking about that, infinite would only apply if we were to never die. Have you ever had surgery where you were anesthetized? It was like they turned your switch off then on again with you never being aware of that time in between. No dreaming, no nothing, your brain was just turned off.

I'm thinking that time is finite and the world and everything I've seen heard and learned is just part of my own organic virtual reality and you and everyone here is just part of it.

Had you never woke up from the surgery, I would still be here because you were just a character in my virtual reality. However, if I had never woke up from my surgery, you and everything else would cease to exist as far as my own consciousness is concerned and time would stop.

I'd better stop, this is getting confusing.......

LOL ... and the matrix? If one considers the matrix, as a possibility, then what the heck? Perhaps there are many thinking there is a matrix. Insanity ... Insanity ... Insanity verses Location ... Location ... Location.
