NASA's Fermi Gamma-ray Space Telescope discovered the first pulsar that beams only in gamma rays. A pulsar is a rapidly spinning neutron star, the crushed core left behind when a massive sun explodes. Astronomers have cataloged nearly 1,800 pulsars. Although most were found through their pulses at radio wavelengths, some of these objects also beam [...]

Fraser. I think we can probably expect to see an asymmetry in the pulse/interpulse/pulse data from this new subset of pulsars, as was shown by Rudak, et al here:http://www.aanda.org/index.php?option=article&access=standard&Itemid=129&url=/articles/aa/full/2002/38/aa2183/aa2183.right.html pete

Sounds like a place the Hulk might want to visit.

The gamma-ray-only pulsar lies within a supernova remnant known as CTA 1, which 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 about 10,000 years ago, emits 1,000 times the energy of our sun. Should this be expressed as energy density within the beam as opposed to energy? Is the true total energy from this object a 1000 times greater than that produced by the sun or is this what it would be if the object radiated uniformly at this intensity?

In the USA we speak and write without sufficient care for detailed accuracy thus training our minds to be willing subjects for scams of all scales.

Is it possible that this odd Pulsar might be a rapidly spining Magnatar?
