Radio-quiet neutron star ten bodies have been proposed as rotation-powered neutron stars that are not visible as radio sources, but are visible as x–ray and gamma ray sources. Indicators that they are indeed neutron stars include them having a high x-ray to lower frequencies emission ratio, a constant x-ray emission profile, and coincidence with a gamma ray source. Quark stars, theoretical neutron star-like objects composed of quark matter, may be radio quiet, according to some theories. More plausibly, however, radio-quiet neutron stars may simply be pulsars which do not pulse in our direction. As pulsars spin, it is theorized they emit radiation from
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
