The Hubble Space Telescope has separated from the shuttle Atlantis

Around 16:00 Israel time, the astronauts on the Atlantis shuttle released the Hubble Space Telescope and performed an evasive maneuver. Now they will check the heat shield again before returning to Earth

STS-125 crew members said goodbye to the Hubble Space Telescope today. After the repair service was completed, the telescope was released from the shuttle's robotic arm at 08:57 EST (15:57 EDT).

Astronaut Megan MacArthur released the holding device, and Commander Scott Altman along with pilot Gregory Johnson instructed Atlantis to carefully move away from the scene. Gentle throbs of the engines moved the shuttle away from the gloom.

Later in the day, the team will devote time to a thorough inspection of the shuttle's heat protection system, including the panels at the front edges of the wings, the bow dome and the tiles on the bottom of the shuttle. Photographic experts will evaluate the data to determine the condition of the heat protection system. As mentioned on Friday, Atlantis is supposed to land at the Kennedy Space Center in Florida.

The fifth and final spacewalk to upgrade the Hubble Space Telescope has ended

  1. This is an interesting piece.
    On a similar topic - I personally claim that the speed of expansion of the universe is slowing down, not accelerating - contrary to the conventional opinion. Details about this can be found on my blog - http://josh.site90.com/wordpress/?p=67

    In any case, if we look at a distance of more than 13 billion light years, what we see is the fog that prevailed after the big bang, and nothing more. We will not be able to see further because the light has not reached us yet.

  2. The question is, will we also be able to see galaxies whose escape velocity exceeds the speed of light?

  3. N. Zemach:
    A more powerful telescope allows us to see things in greater detail (higher resolution that allows us to distinguish more easily between the different stars of a distant galaxy) and also to notice the faint glow of very distant stars that the previous telescope did not allow for its discovery.
    In any case, it is only a matter of better utilization of radiation that has already arrived.

  4. Michael, thank you for your answer, this matter that all the matter in the universe was concentrated in one small point - the mind simply cannot understand (after all, even if you completely eliminate the spaces between the atom and its particles, a simple calculation will show that this concentrated "matter" should occupy a large volume in trillions times trillions
    times than just a small dot)

    The matter of the strength of the telescope did not occur to me. After all, before the Hubble was placed in its place, we also saw at a distance of about 14 m light years? What, a more powerful telescope won't "see" to a greater distance?

  5. N. plant:
    The more powerful a telescope is, the better it is to absorb the light and improve the sharpness of the image, but all the telescopes in the world will not be able to show you objects whose light (or other electromagnetic radiation) coming out of them has not yet had time to reach us.
    Therefore no telescope will allow you to see beyond the limits of the so-called "visible universe" even though there may certainly be stars far beyond those limits.

    To see the light of the big bang there is no need for a far-seeing telescope.
    We perceive this "light" all the time and call it "background radiation". These are the remnants of the radiation of the big bang which, due to the expansion of space, "cooled down" a lot.
    This radiation washes over the entire universe and has no particular source and this is because the big bang happened everywhere in the universe! Yes, here too - where I sit and write and where you sit and read. The space is the one that spread and the same point where the whole universe was concentrated at the time of the big bang is today "spread" over the whole universe.

  6. The most distant galaxies observed from Earth are at a distance of about 13.7
    A billion light years. And those galaxies are (according to what we know today) from the initial period after the big bang.
    My questions are: Suppose (just suppose) that a 100 times stronger telescope is placed in space
    (or a thousand) from the Hubble telescope:

    A. Is it possible for us to see galaxies even at a distance of 20 or 100 billion light years?

    B. Is it possible that we will "see" the bang itself? And if not, why not?
    We looked even further than 13.7 billion light years. What is the chance that we would have discovered hundreds and billions of other universes? After all, until a few decades ago we didn't even know that there were other galaxies besides "ours"?

    C. And if we see the big bang does that mean it happened "there"? And if we were to look in exactly the opposite direction, we would see something else, or even "there"
    We would see the bang.

    I happen a lot on this site which is a very interesting site, but most of the comments
    And arguments revolving around matters with 3 and 4 disappear, while questions of multiplication and division (like my questions) do not receive answers.

    I will thank whoever takes the challenge and tries to answer me at the required level.
