    If you hold a pin at arm’s length up in the air, the head of the pin covers approximately the amount of sky that appears in the Hubble Deep Field. The iconic 1995 image is crowded, not because it’s a broad swath of sky but because it’s a broad swath of time. The Hubble Deep Field is more than 12 billion light-years deep.

    Robert Williams was the director of the Hubble’s science institute back in 1995, and it was his decision to attempt a deep field observation with the telescope. Previous calculations had indicated that Hubble would not be able to detect very distant galaxies, but Williams figured they’d never know unless they tried.

    His team chose a completely dark part of the sky, in order to see beyond the stars of the Milky Way, and programmed Hubble to stare at that spot for 10 days. It was unusual to use precious observing time to point the telescope at nothing in particular, but that’s what they did.

    "We didn’t know what was there, and that was the whole purpose of the observation, basically — to get a core sample of the universe," Williams said, borrowing the concept of the "core sample" from the earth sciences.

    "You do the same thing if you're trying to understand the geology of the Earth: Pick some typical spot to drill down to try to understand exactly what the various layers of the Earth are and what they mean in terms of its geologic history."

    What makes the Hubble Deep Field an atypical core sample is that rather than observing the material as it is now, the telescope collected images of galaxies as they appeared millions and billions of years ago. Since light can only travel so fast, the telescope is a peephole into the history of the universe.

    Still blurry, just wait for the Webb telescope

    I hope the day comes or is here we place telescopes on stationary locations. IE the far side of the moon. Or find a way to "park" them in a segment of space.

    they usually spend OUR taxes on their projects and keep it to themselves until they get bored with it, then release it

    A CAMERA TRAVELING AT 17000MPH TAKING CRYSTAL CLEAR PICTURES OF PITCH BLACK SPOTS. LUCKY THAT EVERYONE IS NOT A PHOTOGRAPHER TO UNDERSTAND HOW SHUTTER SPEED AND MOVEMENT WORKS.

    Actually, the Hubble doesn't take photos

    I disagree with the personal belief of astronomers of the past that astronomy is intellectual property. It is knowledge that should be shared universally. And luckily that sentiment is true with NASA...well, as far as we know anyway.

    Ha Sido un telescopio muy importante estos años pronto llegará el James wedd telecopio ampliando NUESTRO CONOCIMIENTO.

    Are photos weighed ? A ton is a lot huh.
    I love how it didn't work but the fix that costs as much ...cough. worked and we all danced.
    Cause it worked.. lol thx for the money sucka.
    Like public schools we all scream spend more money .. better believe it.
    Like buying a Harley Davidson then spending as much to make it work.
    We Americans are doopid

    If space is a vacuum, then there is nothing between the galaxies but... NOTHING.... so... If NOTHING separates two galaxies from each other, then they must be... very CLOSE! 😜

    The Hubble "telescope" does not take photos people. It transmits data such as numerical information not photos!!! Search it up for yourself it's not difficult. Unbelievable!!!
