  Mar 19, 2015 Electric Universe theory assumes Earth and the Sun are electrically connected. Previous Picture of the Day articles discuss the linkages between the flow of electric charge through the galaxy, solar electric currents, and terrestrial electric currents. Earth’s environment is also driven by those cosmic electrical circuits, but…

Fixing a Hole

  Mar 18, 2015 “It really doesn’t matter if I’m wrong, I’m right…” The Max Planck Institute added more fuel to the black hole physics fire: the ejection of a “supermassive black hole” (SMBH) from its parent galaxy. Researchers in the department of Extraterrestrial Physics measured what appear to be…

Plasma Star

Mar 16, 2015 Recent images of the star CH Cygni reveal the electrical circuitry that drives it. Radiation in radio (blue), optical (green), and X-ray (red) highlight the several inner components of the plasma discharge. The outer red circle (large optical image) is composed of radial filaments. This is a…

Titanic Sculpture

  Mar 13, 2015 The features on Saturn’s moon Titan are not caused by flowing liquids. The Cassini-Solstice spacecraft has been analyzing information from the planet Saturn and its family of moons for more than eleven years, now. Its primary mission target continues to be Titan, the largest moon in…

Unfaithful Geysers

  Mar 12, 2015 Previously detected “plumes” on Europa are no longer visible. When Voyager 1 flew by Europa on March 1979, planetary scientists were surprised to see that the moon seemed to be completely encased in water ice. Another surprise was that Europa exhibited few craters. Instead, its surface is…
