Astronomy Fun Fact:A pulsar's magnetic field is so strong that it causes most of the light and radiation that the neutron star emits to be concentrated into cones of emission, like beams from a lighthouse. In fact, the key to a pulsar is the combination of the extraordinary magnetic field and the rotation of a neutron star. If the neutron star is spinning, like the Earth rotates on its axis, and if the Earth happens to lie in the path of the beams, we see a pulse of light each time a beam sweeps across the earth.
Get on the APOD PING list!

APOD PING!

Here's the Chandra x-ray image of the central part of the Crab.
Chandra's X-ray image of the Crab Nebula directly traces the most energetic particles being produced by the pulsar. This amazing image reveals an unprecedented level of detail about the highly energetic particle winds and will allow scientists to probe deep into the dynamics of this cosmic powerhouse.

The Crab has always been my favorite; seeing it through the eyes of Hubble was interesting, to say the least.

Wow! Thanks for the link. This is one of the nicest on that link!
To: MeeknMing
Yepp, that's also one of my favorite, though I like the Sombrero galaxy better:
But that's just my opinion (I'm going to order all of them anyway
)
