Solar Corona Preview of Today's Total Eclipse --"What the Sun's Aura of Plasma Will Look Like as It Extends Millions of Kilometers Into Outer Space"  

Today, August 21, 2017, a total eclipse of the Sun will be visible across the U.S. tracing out a 70-mile-wide band across 14 states. Beyond their rarity and otherworldly nature, solar eclipses help astronomers better understand the Sun - its structure, inner workings and the space weather it generates. They also provide an opportunity for researchers who study solar science to forecast in advance how the Sun will look during the eclipse - proving their predictive chops, so to speak. A team

Gigantic Bubbles at Center of Milky Way Reaching Out 50,000 Light Years Discovered to be Source of Mysterious Cosmic Rays  

    A team of scientists from Russia and China has developed a model which explains the nature of high-energy cosmic rays (CRs) in our Galaxy. These CRs have energies exceeding those produced by supernova explosions by one or two orders of magnitude. The model focuses mainly on the recent discovery of giant structures called Fermi bubbles. Hints of the Fermi bubbles' edges shown above were first observed in X-rays (blue) by ROSAT, which operated in the 1990s. The gamma rays mapp

"Not Alien Signals" --FRB's are Pulses from Dark-Matter Stars Captured by Supermassive Black Holes of Early Universe  

  New research seems to suggest that mysterious fast radio bursts might be stars made of dark matter crashing into black holes, according to Aiichi Iwazaki, an astronomer at Nishogakusha University in Tokyo, who  subscribes to the theory that dark matter is made of theoretical particles called axions, very light and long-lived particles that only interact with matter in very weak ways, such as through gravity, the weakest force in the universe. Scientists know dark matter exists b
