    SUMMARY: Astronomers using the Australia Telescope Compact Array have found a rapidly spinning neutron star which is spitting out jets of material at nearly the speed of light. Jets like this have only been seen previously coming out of black holes, and this discovery challenges the theory that only the environment around a black hole can be so energetic. The astronomers studied Circinus X-1, an object located about 20,000 light years away, which is a bright source of X-rays. They know it's a neutron star, but it also has these unusual characteristics.

    What do you think about this story? Post your comments below.

    Wonderful! Is this a life cycle of Black Hole emissions seen for the first time?

    XTE J1550-564 which is about 17,000 light years, similiar?

    Whatever process accelerates jets to near the speed of light, it does not rely on the special properties of a black hole.
    "The key process must be one common to both black holes and neutron stars, such as accretion flow," says Dr. Kinwah Wu of Unversity College London, UK.
    This is a case of an unproven assumption, we have never seen any material going in towards a neutron star/black hole yet is is always invoked to explain the X-ray production. The most efficient way of generating X-rays is not heat, but particle acceleration (that's how our dentist can make an X-ray photograph). And what is needed to accelerate particles? Right, an electric/magnetic field.
    Neutron stars and black holes are just stars under extreme electrical conditions.
    Cheers.

    So this is what they mention before, the plasma?

    Yes, plasma is the result whenever electric currents are available, and to become a plasma (in space) only very small amounts of charge are necessary.

    I found a article which is about Matter convert to Plasma, and they do have a little information about this topic
    Take a look ^^

    Thanks, this is what happens at small scales, but large scale events like the jets formed by black holes, only need more current to be produced (electrical phenomena can be scaled up easily). Here http://www.electric-cosmos.org/galaxies.htm more jets and how they form are discussed.
    Cheers.

    The electric universe doesn't believe there are black holes or neutron stars.
