    Default Neutron Stars

    Neutron stars
    These stars are bigger several times than that of sun. They are formed as a result of a supernova. Supernova is an explosion of stars, when these stars have running out their nuclear fuel, they explode. When they explode their materials, electrons and protons, squeeze together to become neutrons so that why we call them neutron stars. A neutron star is very heavy because the neutrons are tightly crammed together into a super dense object that one sugar cube of its material weighs about 100 million tons, which is about as much as a mountain. Therefore as a star gets smaller, its mass gets heavier.
    A Neutron star has a very high rotation speed. It can spin several hundred times per second. That creates intense magnetic fields around it and when it rotates, it produces a sound similar to a hammer, So that why the astronomers call it 'a gigantic hammer'.
    Some people ask how could we hear neutron stars' sounds while the closet one is hundreds of light years from earth? Well, neutron stars produce regular beams of radio waves, these beams are received by radio telescopes then converted into sounds. And here I want to indicate that some astronomers entitle these stars as pulsars but that naming isn't perfect because in the beginning astronomers thought that their sounds are similar to pulses but later they discerned that the proper name would be hammer so they gave them the name of gigantic hammers. Definitely, the sounds that they produced are akin to the hammer's sound.

    Thanks alot

    Hi Soup. Thanks again
    what about these changes?

    These stars are several times bigger than the sun. They are formed as a result of a supernova. A Supernova is an explosion of stars, when these stars run out of their nuclear fuel, they explode. When they explode their materials, electrons and protons squeeze together to become neutrons which is why they are called neutron stars. A neutron star is very heavy because the neutrons are tightly crammed together into a super dense object that means one sugar cube of its material weighs 100 million tons, which is about as much as a mountain. Therefore as a star gets smaller, its mass gets heavier.


    A Neutron star has a very high rotation speed. It can spin several hundred times per second to create intense magnetic fields around it and when it rotates, it produces a sound similar to a hammer and that's why astronomers call it 'a gigantic hammer'.

    That's better.

    Here are a few more to work on:


    1. capitalization error
    A Supernova is an explosion of stars ...

    2. comma splice error
    ... , when these stars run out of their nuclear fuel, they explode.

    3. punctuation help
    When they explode, their materials, electrons and protons squeeze together to become neutrons. Which is why they are called neutron stars.

    4. Meaning is awkward; needs to be reworded
    ... crammed together into a super dense object that means one sugar cube of its material weighs 100 million tons, ...

    ... crammed together into a super dense object with _____ of its material weighing 100 million tons, ...
    -------------------------
    A Neutron star has a very high rotation speed. It can spin several hundred times per second to create intense magnetic fields around ...

    A supernova is a star in the process of explosion. A neutron star is a neutron star because of implosion, not explosion. It is called a neutron star because it is composed of neutrons. It is very dense.

    Neutron stars have the strongest magnetic fields in the known universe.

    The stars that eventually become neutron stars are thought to start out with about 8 to 20-30 times the mass of our sun.

    A neutron star is about 20 km in diameter and has the mass of about 1.4 times that of our Sun. This means that a neutron star is so dense that on Earth, one teaspoonful would weigh a billion tons! Because of its small size and high density, a neutron star possesses a surface gravitational field about 2 x 1011 times that of Earth. Neutron stars can also have magnetic fields a million times stronger than the strongest magnetic fields produced on Earth.

    Simply put, pulsars are rotating neutron stars. And pulsars pulse because they rotate!
