    Hubble scientists have released the most detailed picture of the universe to date, containing 265,000 galaxies.

    This Hubble Space Telescope image represents the largest, most comprehensive "history book" of galaxies in the universe.

    The image, a combination of nearly 7,500 separate Hubble exposures, represents 16 years' worth of observations.

    The ambitious endeavor, called the Hubble Legacy Field, includes several Hubble deep-field surveys, including the eXtreme Deep Field (XDF), the deepest view of the universe. The wavelength range stretches from ultraviolet to near-infrared light, capturing all the features of galaxy assembly over time.

    The image mosaic presents a wide portrait of the distant universe and contains roughly 265,000 galaxies. They stretch back through 13.3 billion years of time to just 500 million years after the universe's birth in the big bang. The tiny, faint, most distant galaxies in the image are similar to the seedling villages from which today's great galaxy star-cities grew. The faintest and farthest galaxies are just one ten-billionth the brightness of what the human eye can see.

    The wider view contains about 30 times as many galaxies as in the Hubble Ultra Deep Field, taken in 2004. The new portrait, a mosaic of multiple snapshots, covers almost the width of the full Moon. Lying in this region is the XDF, which penetrated deeper into space than this legacy field view. However, the XDF field covers less than one-tenth of the full Moon's diameter.

    Looks like a paper on the sidewalk. Links did not open. I was expecting a picture along these lines. . thsaturn.jpg

    This is the image (not the highest rez version, that takes a while to load). Each point of light is a galaxy, not a star.

    So what are the rough edges? Areas that.m couldn't be mapped or nonexistent space?

    Thats impressive considering each one is a galaxy.

    Just the limits of the mapping data. What's represented in that image is an absolutely unfathomable amount of area.

    nitpicking, but wouldn't it be "volume"? ;)

    and to get all metaphysical and shit, at some point wouldn't there be time shift as well? What's volume x time?

    Both fair points. I was using "area" in the colloquial sense, not the mathematical sense. ;) As for the time shift--that's certainly a way to look at this data. I'd say we're still just looking at a physical area (or volume!) of the universe, but what we see when we look there tells us something about the past. Philosophically, though, it's a good question as to whether there's any distinction. Whenever we look at anything, even just the sandwich we're eating, we're technically looking back in time.

    And volume x time is spacetime.

    I thought Hubble was being retired.

    Yes, but this keeps him busy. Mrs. Hubble doesn't want him just sitting around the house all day.

    Every speck of light in that picture has traveled for millions or billions of years longer or shorter than the speck next to it, in order to make it’s appearance at the lens of our telescope. We’re seeing many different eras in time, separated by eons, all at once in a single 2D image. It’s actually a lot to take in for appearing to be just a bunch of dots and smudges on a flat surface.

    If you really squint your eyes you can see Jack Benny as a young boy on one of those distant planets revolving around one of those stars in one of those distant galaxies.
