Stellar Mass

January 17, 2020 High-velocity particles in orbit around some stars seem to indicate relativistic effects. Part of what physicists are trying to understand is the observation of spectral lines from “hot iron atoms” that appear to orbit close-in to the surfaces of neutron stars. As interpreted by conventional theory, the…

Moving Charges

January 16, 2020 Astronomers see magnetism but not electricity. Scientists working with dynamos (an abbreviation of the nineteenth century term, electric-dynamo) think they found clues to how stars and galaxies acquire their magnetism. Turbulence in plasmas forms small magnetic fields, but scientists struggle to understand how those small fields coalesce…

Ionization

January 15, 2020 Charge separation drives galactic formation. As written many times in the past, galaxies travel within a circuit of electricity flowing through the cosmos. Electricity organizes itself within masses of plasma that can be larger than galaxy clusters. Since plasma is primarily composed of neutral atoms, but with…

Electric Furrows

January 14, 2020 Images of Saturn’s moon, Dione reveal trenches and cliffs. The Cassini-Huygens mission was launched from Cape Canaveral on October 15, 1997. Few now remember the public outcry against the mission. There were several attempts by citizens groups and the ACLU to stop the launch, because 33 kilograms…

Stellar Vibrations

January 13, 2020 When asking, “what are stars?”, the question might seem self-evident, since they are almost always described as intensely bright, burning balls of hydrogen gas. Any particular star’s size, therefore its gravitational attraction, is what conventional astronomers say holds the planets in their orbits. Stellar fusion fire is…

As Above So Below

January 8, 2020 What happens in space affects Earth. NASA launched the Advanced Composition Explorer (ACE) spacecraft on August 25, 1997. From its location at LaGrange point L1, ACE analyzes the solar wind, providing real-time “space weather” reports about geomagnetic storms. ACE should be able to continue its mission until…

Not a Crater?

January 7, 2020 The terrain found in Australia is not easy to explain using conventional theories. Many previous Picture of the Day articles discuss the continent of Australia. Wilpena Pound, Uluru, the Olgas, and the coastal topography seem to disprove gradual processes of sedimentation and erosion over millions of years….

Slow Down!

January 6, 2020 Is dark energy speeding everything up? Dark energy is considered a necessary adjunct to the Big Bang theory, because distant galaxies appear to be accelerating as they recede from Earth-based observatories. Recessional velocity is something that astronomers believe contributes to the redshift of those objects. Redshift is…
