Electric Aurorae

Feb 26, 2019 There is an electrical structure called a magnetotail extending away from Earth for millions of kilometers. In 1966, the U.S. Navy satellite, TRIAD, recorded electromagnetic disturbances as it passed over Earth’s poles and through the Van Allen Radiation Belts. Those vertical electric currents that flow to Earth from the…

Fusion Confusion

Feb 25, 2019 Coronal holes are the source of fast solar winds that can produce geomagnetic storms on Earth. The thermonuclear model of the Sun proposes that the temperature in its core is more than 15 million Celsius, with compressive strain greater than 340 billion times Earth’s atmospheric pressure. 700…

Cut the Dust

Feb 22, 2019 Stars are formed from charged particles. “Men think highly of those who rise rapidly in the world; whereas nothing rises quicker than dust, straw, and feathers.”— Lord Byron Immanuel Kant, the 18th Century philosopher, suggested that stars, in general, as well as the Solar System, in particular,…

How’s the Weather?

Feb 21, 2019 Neptune’s clouds contradict consensus viewpoints. On July 12, 2011 Neptune completed its first orbit around the Sun since it was discovered on September 23, 1846. This means that observations are limited, since great distance strains technology’s ability. Spectrographic data about Neptune, for instance, is limited to the…

Ice Moon

Feb 20, 2019 A new mission to Europa. The Galileo spacecraft entered orbit around Jupiter in December 1995. When it ran out of maneuvering fuel, the 320 kilogram probe was incinerated by the Jovian atmosphere, so that it would not crash into one of Jupiter’s moons, particularly Europa. Planetary scientists were surprised…

Forbidden Doughnut

Feb 19, 2019 A ring of galactic plasma. There is a twisted ring of material surrounding the nucleus of Galaxy Centaurus A; an “active galaxy” that exhibits axial jets and a doughnut-shaped plasma discharge. Active galaxies are brighter than other galaxies of the same type, since they radiate excess energy…

Eternal Winter

Feb 15, 2019 This small moon is said to be covered with powdery snow. The Cassini mission is now over. However, more data continues to be analyzed, particularly those observations of various moons, including Enceladus. Enceladus was named after one of the Gigantes, or Titans, in Greek mythology. Its name…

Cassini’s Legacy

Feb 14, 2019 Data from the now defunct Cassini mission provides more clues to Saturn’s environment. Cassini-Huygens was launched from Cape Canaveral on October 15, 1997. Its primary mission was to explore the Saturnian system, including the atmosphere, rings, magnetosphere and a number of its moons. As Cassini made its final weekly…
