New Class of Pulsars Discovered

xyz writes "NASA's Fermi Gamma-ray Space Telescope has discovered a new class of pulsars which emit purely in gamma rays. A pulsar is a rapidly spinning neutron star, and of the nearly 1,800 cataloged so far, only a small fraction emit at frequencies higher than radio waves. The gamma-ray-only pulsar, which lies within a supernova remnant known as CTA 1, is silent across parts of the electromagnetic spectrum where pulsars are normally found, indicating a new class of pulsars. It is located 'about 4,600 light-years away in the constellation Cepheus. Its lighthouse-like beam sweeps Earth's way every 316.86 milliseconds. The pulsar, which formed in a supernova explosion about 10,000 years ago, emits 1,000 times the energy of our sun.'"

    Odd thing is that the signal seems to be carrying a message. We have decoded it, and it seems to read: F-I-R-S-T---P-O-S-T-.

    No natural object is spinning that fast.

    You are obviously not aware about the United States forefathers in their graves, knowing what is going on in that nation.

    3 busses will come within 316.86 milliseconds of each other,
    then you'll wait 10,000 years for the next one.

    You obviously do not smoke. A surefire way to make that next bus come is to light one up.

    Quantum mechanics you insensitive prick!

    If only you hadn't looked at the report card. Then, your grade could've been an A or an F, and you wouldn't have known until you looked at the report card, thus collapsing the waveform.

    And now you know why you only got a C.
