Pulsar star. The neutron star retains most of its angular momentum, and since it has only a tiny fraction of its progenitor's radius (and therefore its moment of inertia is sharply reduced), it is formed with very high rotation speed. A beam of radiation is emitted along the magnetic axis of the pulsar, which spins along with the rotation of the neutron star. The magnetic axis of the pulsar determines the direction of the electromagnetic beam, with the magnetic axis not necessarily being the same as its rotational axis. This misalignment causes the beam to be seen once for every rotation
A Beam of Sun to Shake the Sky A Beam of Sun to Shake the Sky A Beam of Sun to Shake the Sky is a public art work by American artist Richard Taylor, located in downtown Milwaukee, Wisconsin. The sculpture was created for the Central Milwaukee Public Library as part of the remodeling of the Wells Street entrance. "A Beam of Sun to Shake the Sky" consists of two vertically oriented sculptures set upon massive granite pedestals in front of the library's glass facade. The sculptures appear made of bright red ribbon-like strips of painted aluminum that snake skyward. The individual strips each contain cut-out letters in
