Cosmic eXploration: Hubble eXtreme Deep Field

In 2004, the Hubble Ultra Deep Field (HUDF) provided a ground-breaking view of distant galaxies. In 2009, those data were augmented with new infrared observations to create the HUDF-IR. In 2012, the Hubble eXtreme Deep Field (HXDF) combined those images along with a complete census of archival datasets to see yet farther into the universe. The HXDF contains roughly 5,500 galaxies stretching over 13 billion light-years of space, and represents astronomy’s deepest view into the cosmos.

This scientific visualization depicts a flight through the HXDF galaxies. Using measured and estimated distances for approximately 3,000 galaxies, astronomers and visualizers constructed a three-dimensional model of the galaxy distribution. The camera traverses through the thirteen-billion-light-year dataset and ends in blackness, not because more distant galaxies do not exist, but because such galaxies have not yet been observed. For cinematic reasons, the exceedingly vast distances in the 3D model have been significantly compressed.

    When one considers the miniscule FOV of the Ultra Deep Field shots and realizes that those are not stars, but instead galaxies, the thought that our small blue ball is the only place where life started and learned how to self-replicate becomes silly.

    Still worried about the Fermi Paradox, though.

      Unless that’s just fancy “wallpaper”. (Kidding. . . for the most part.)

    Galaxies, not just stars…. Our Milky Way is just one.

    What I found irritating is, they managed to slip in a cute swipe at the “young earth” creationists (which is fine – and a graphic demo of why we’re living in “Jehovah’s matrix” if true).
    But how can they can go all these episodes without a poke at the astrology nuts – is telling.
    The Fermi Paradox worries me too.
    I figure Sally will show up any day now, certainly before we attain the singularity and produce a real threat to the galactic mech civilization.

      Ooops, sorry got this mixed up with a comment on “Cosmos”.

        Actually, going after creationists and not astrologers makes sense. In the late 70’s/early 80’s, newage like astrology was a lot more troublesome than it is today, while today creationism and related religi-woo are the biggest immediate dangers to an educated public.

          Now there, I profoundly disagree.
          I’m probably influenced by where I live in “The People’s Republic of Boulder”, but I could go the rest of my life and never encounter or have to deal with creationists.
          But when I go to the supermarket, there’s 4 isle’s of homeopathic crap for sale, my horoscope is on my Direct TV guide, the local paper, and every check-out line and there’s a newage “healing” center on every corner. I’m forced to pay for all sorts of quack medical stuff (one more hidden side of ‘O care) and the scientifically illiterates have banned fracking around here. Not to mention, the anti nuclear power hysteria eco-religion that’s profoundly affecting our future.
          In the 70s/early 80s new age religi-woo was somewhat novel. Now you don’t notice it because it’s gone mainstream. It’s ubiquitous.
          It is, in fact, possible to be a Christian fundamentalist AND also be a good engineer (exactlty how – I’m not sure) because I’ve worked with many over my carrier. But I’ve NEVER met an engineer who was into Crystal astrology.
          In the 1950s & 60s, America was a MUCH more religious nation than it is today. I’ll wager 1/4 or better of the engineers working on Apollo (remember it was Johnson’s WPA project for the South) were church-going Christians who professed fundamentalism.
          We still somehow managed to beat those godless commies to the moon.
          I can only offer anecdotes, but in my experience most fundamentalist types make sure their kids have a MORE rigorous STEM education (except certain parts of biology of course) than the average regular secular American.
          The new age lefties wear science on their sleeve and wrap themselves in self rigorousness about it, but the neo-Luddites and anti-modernity crowed are firmly ensconced on the left coast and they Always get a pass. If you’re all worried about Global Warming, then there’s THE big dilemma, because at its core the eco religion has no real solutions except make pretend windmills to charge the Prius while all the people in dirt world should just live in abject poverty and die.
