The x-ray source at the core of NGC 300 is designated NGC 300 X-1. Astronomers speculate that NGC 300 X-1 is a new kind of Wolf-Rayet black hole binary system similar to the confirmed such system IC 10 X-1. Their shared properties include an orbital period of ~30 hours and x-ray brightness of ~1×1038 ergs.

Famous quotes containing the words black, hole and/or system:

    A major problem for Black women, and all people of color, when we are challenged to oppose anti-Semitism, is our profound skepticism that white people can actually be oppressed.
    Barbara Smith (b. 1946)

    Wondrous hole! Magical hole! Dazzlingly influential hole! Noble and effulgent hole! From this hole everything follows logically: first the baby, then the placenta, then, for years and years and years until death, a way of life. It is all logic, and she who lives by the hole will live also by its logic. It is, appropriately, logic with a hole in it.
    Cynthia Ozick (b. 1928)

    How natural that the errors of the ancient should be handed down and, mixing with the principles and system which Christ taught, give to us an adulterated Christianity.
    Olympia Brown (1835–1900)
