Jul 6, 2018 What energizes this nebula to such extremes? Picture of the Day articles note that many structures in the galaxy are active energy sources, ejecting charged matter from their poles, leaving long braided tails, or revealing formations of tightly bunched filaments. A detailed image of Eta Carinae reveals a…

Truth or Fashion

  Jul 5, 2018 If currently fashionable theories are Ultimate Truth (or at least smart ideas) and myth was stupid superstition, where is the dividing line? Was Ptolemy stupid and Newton smart? But General Relativity is not just an improved version of Newton’s theory, it’s different: Einstein’s stretchable space-time is…

Reconnoitering Ryugu

Jul 4, 2018 Most asteroids are presumed to be loosely compacted “rubble piles”. On December 3, 2014 the Japan Aerospace Exploration Agency (JAXA) launched Hyabusa 2 from the Tanegashima Space Centre in Japan, on a sample return mission to the near Earth asteroid (NEA), Ryugu. Hyabusa 2 follows on the…

Electric Light

Jul 2, 2018 How does the Sun produce heat and light enough to sustain life on Earth? Spectrograms of the Sun reveal that it is made-up almost entirely of hydrogen (71%), helium (27%) and some minute percentages of oxygen, nitrogen, sulfur, carbon, and six other elements. Every element is present…

  Jun 28, 2018 Is the Universe expanding? “As a general scientific principle, it is undesirable to depend crucially on what is unobservable to explain what is observable, as happens frequently in Big Bang cosmology.” — Halton Arp Electric Universe theory states that stars are born where regions of space…

Different Eyes

Jun 27, 2018 Why are stars so unalike? “If everyone is thinking alike, then somebody isn’t thinking.” — George S. Patton It is a mystery to astronomers why stars exhibit such distinctive characteristics, because the stars, including the Sun, are thought to form from the same mix of elements in…

Gigantic Jets

  Jun 26, 2018 Lightning-like electric discharges occur above the clouds. Capacitors accumulate and store electric charge in two conductive plates separated by a dielectric insulator. Charge on one plate attracts opposite charge to the other, creating an electric field that forms an electrical energy reserve. The electric field between…

Tracks in the Dust

Jun 25, 2018 Dust storms occasionally engulf Mars. On Mars, dust storms are not diffuse and separated like those on Earth, they are caused by tornado-like whirlwinds whose tops reach higher than Mt. Everest. They appear to draw surface dust up through thousands of sky-high funnels and carry it for…

Against the Wind

  Jun 21, 2018 Electricity moves the Universe. “To try to write a grand cosmical drama leads necessarily to myth. To try to let knowledge substitute ignorance in increasingly larger regions of space and time is science.” — Hannes Alfvén The movement of electric charge through plasma-state material generates electromagnetic…
