Cygnus X-1

  Nov 08, 2012 Without a theory of electricity in space, astronomers must explain cosmic lightning with theories of falling gas. To get x-rays from falling gas, the gas must be attracted to a source of gravity with orders-of-magnitude more force than any known density of matter. Nevertheless, with suitable…

Cluster Wires

  Nov 06, 2012 A galaxy-wide filament connects two galactic clusters. The Herschel Space Observatory possesses the largest mirror ever launched into space: 3.5 meters in diameter. Herschel entered orbit around LaGrange point L2 (behind Earth in relation to the Sun) in July 2009, so that its extremely sensitive, supercooled infrared detectors…

Frozen Fires

  Nov 02, 2012 The Chandra X-ray Telescope has puzzled astronomers with the discovery of abnormally high temperatures at the core of the Milky Way. A news release announcing this image of the center of the Milky Way stated that the X-ray spectrum of the gases is consistent with a…

Daughter of Heaven

  Oct 30, 2012 Recent analyses suggest that Saturn’s moon Phoebe resembles a planet. Saturn’s moon Phoebe is comparatively small, roughly 220 kilometers in diameter. Its surface gravity is 0.224m/s^2, compared to the 9m/s^2 on Earth. Phoebe is also as black as night, making it one of the darkest objects in the Solar System….

Troubles With Bubbles

  Oct 26, 2012 Both nuclear powered stars and electrically powered stars produce bubbles in the plasma surrounding them. From that common observational beginning, the theoretical explanations diverge. Nuclear generated bubbles come in two types: planetary nebulae (PNs) and supernova (SN) remnants. The PNs are bubbles that are produced during…
