Conspicuous Absence

  Nov 11, 2015 Astronomers see magnetism but not electricity. According to a recent press release from Princeton University’s Plasma Physics Laboratory (PPL), scientists working with dynamos (an abbreviation of the nineteenth century term, electric-dynamo) think they found clues to “an enduring mystery…how stars and galaxies acquire their magnetic fields.”…

Spacequakes

  Nov 10, 2015 The Sun triggers magnetospheric oscillations on Earth. It has become more apparent to conventional scientists that Earth’s ionosphere is connected to the Sun by filaments of electric charge, so the upper levels of the atmosphere experience the Sun’s influence. This idea has long been a tenet…

No Dynamo Hum

  Nov 9, 2015 Was Mars once warm and lush? NASA launched the Mars Atmosphere and Volatile Evolution Mission (MAVEN) on November 18, 2014 on a year-long investigation of Mars’ upper atmosphere, its ionosphere, and how it interacts with the solar wind. The spacecraft is fitted with instruments that are…

Flash in the Pan

  Nov 6, 2015 Black hole physics in the news again. NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) was launched aboard a Pegasus rocket on June 13, 2012 from a NASA L1011 aircraft. According to a recent press release, NuSTAR captured images of a so-called “supermassive black hole” (SMBH) erupting with…

Plasma Contortions

  Nov 5, 2015 Rather than black holes, electricity should be considered. Electric Universe advocates propose that electric currents in plasma generate magnetic fields that constrict the current flow. As previous Picture of the Day articles point out, the constricted channel is known as a “Bennett pinch,” or “z-pinch.” Pinched…

Tempestuous Ariel

  Nov 3, 2015 Another moon with unmistakable signs of electric discharge impacts. The moon Ariel is pockmarked with craters ranging from five to ten kilometers across—almost undetectable in the image above—however, a few craters measuring 20-30 kilometers across are visible. The crater dimensions might seem small, but considering Ariel’s equatorial…

Super Spot

  Nov 2, 2015 A star with a spot out of proportion to its size. According to a recent publication, “starspots” are seen on the surface of XX Trianguli, otherwise known as HD 12545. The puzzling aspect is that there is only one spot visible and it covers almost one-third…
