    Supposedly this molecular cloud is responsible for producing 50% of the
    new stars near the glactic center.

    The molecules that this molecular cloud is composed of have been created
    by astrochemistry for the last 13 billion years. It took around 8
    billion years for the elements making up our solar system to be created,
    but in the star rich galactic core it would not have taken that long.
    The problem is that no life could have time to evolve when so many stars
    are forming and dying in such a limited volume of space.

    Sagittarius B2 is composed of hydrogen and carbon monoxide, but it is particularly noted for containing a wide variety of complex organic
    molecules, including alcohols like ethanol and methanol, and even sugar molecules like glycolaldehyde, as well as branched molecules like
    isopropanol and isopropyl cyanide. These molecules, detected via radio astronomy, are found in the densely packed regions of the cloud where
    new stars are forming, indicating its importance as a nursery for astrochemistry and star birth.

    Saw this report. Also have to wonder about radiation levels (of
    various types) in the galactic center.

    So

    What is the distribution of these? Observations towards the
    center may be more difficult?

    I considered the radiation. We might not survive the cosmic rays from
    our own sun if we did not have a magnetic field. The solar cosmic rays
    are supposed to penetrate 25 meters into the earth's crust.

    Just imagine what type of sunblock we would need when you lived in
    perpetual daylight due to all the neighboring stars filling the sky, and sunblock won't protect you against the charged particle bombardment.

    My guess is that most of the small single stars, about the size of our,
    have planets around them. There was not enough mass to generate a
    larger star or a binary system, and their smaller size would allow more
    of the mass in the dust cloud that they formed in to produce planets
    instead of being sucked into the center of the solar system.

    I googled the subject and even though Sagittarius B2 is responsible for producing 50% of the new stars within 100 light years of the center of
    our galaxy it is relatively poor in stars (about 1/10) compared to the
    rest of the galaxy around 100 light years from the galactic center. It
    still has around 1 million stars per cubic parsec while the rest of the
    area around it has around 10 million stars per cubic parsec. Around our
    solar system there are only 0.14 stars per cubic parsec. Proxima
    Centari is over a parsec away. It is hard to imagine having over a
    million stars filling the volume of space around us and between us and
    our nearest stellar neighbor.

    Life as we know it likely could not survive that close to the galactic
    center.
