Island Universes

  Sep 30, 2013 Galactic magnetic fields were discovered more than 50 years ago. Astronomers continue to ask basic questions about galaxies: what generates their magnetic fields? What gives those fields their shape and their strength? Researchers using the latest computer simulations think they have found the answers. Cool gas…

Double Rainbow

Sep 26, 2013 External electric flux influences Earth’s climate According to a recent press release, ten years of data analysis has revealed that cloud height changes over time in response to an electric field generated by “global thunderstorms”. Although Earth’s electric field is brought into the discussion, and the electric charge…

Blast of Gas

  Sep 20, 2013 The large ALMA radio telescope in Chile has discovered that “billowing columns” of “gas” are “fleeing” from gravitational forces that would snare them into new stars. The size of the Sculptor Galaxy depends on the outcome. Unless, of course, star formation is not so much a…

The Hairy Universe

Sep 18, 2013 Popular accounts of nebulas usually omit mention of their “hairy” structure. Because gravity can’t produce long, evenly spaced filaments of matter, astronomers don’t talk about them. Perhaps they don’t even see them. This double nebula is located in the Large Magellanic Cloud, a small, irregular galaxy that’s considered to…

Orbital diagram of comet 2012 S1

  Sep 17, 2013 Are comets “dirty snowballs”? (This TPOD originally ran on Apr 01, 2013) Comet 2012 S1, an object approximately three kilometers in diameter, is presently inside the orbit of Jupiter. It is “remarkably bright” according to astronomers, although it is still millions of kilometers from the Sun….
