NASA’s Cassini Spacecraft discovers Plasma changes at Saturn

Pasadena, CA – Researchers working with data from NASA’s Cassini spacecraft have discovered one way the bubble of charged particles around Saturn — known as the magnetosphere — changes with the planet’s seasons.

The finding provides an important clue for solving a riddle about the planet’s naturally occurring radio signal. The results might also help scientists better understand variations in Earth’s magnetosphere and Van Allen radiation belts, which affect a variety of activities at Earth, ranging from space flight safety to satellite and cell phone communications.

Laurel, MD – Just 96 days since their launch, NASA’s twin Van Allen Probes have already provided new insights into the structure and behavior of the radiation belts that surround Earth, giving scientists a clearer understanding about the fundamental physical properties of these regions more than half a century after their discovery.

In a press conference at the American Geophysical Union’s 2012 Fall Meeting in San Francisco, members of the Van Allen Probes science team discussed current findings made in unlocking the mysteries of the radiation belts.

Washington, D.C. – In space, they say, no one can hear you scream.

Nobody ever said anything about singing, though. A NASA spacecraft has just beamed back a beautiful song sung by our own planet.

“It’s called chorus,” explains Craig Kletzing of the University of Iowa. “This is one of the clearest examples we’ve ever heard.”

NASA’s Polar spacecraft data helps researcher find Hidden Portals in Earth’s Magnetic Field

Written by Dr. Tony Phillips
Science at NASA

Washington, D.C. – A favorite theme of science fiction is “the portal”–an extraordinary opening in space or time that connects travelers to distant realms. A good portal is a shortcut, a guide, a door into the unknown. If only they actually existed….

It turns out that they do, sort of, and a NASA-funded researcher at the University of Iowa has figured out how to find them.

Essayist Ashley Butler to give nonfiction reading at APSU on November 7th

November 2, 2011 |

Clarksville, TN – In her new collection of essays, “Dear Sound of Footstep,” author Ashley Butler tackles such strange subjects as the fastest man on earth and the bizarre, echo-free chamber at Harvard University. But if you were to ask someone who read this compelling work what it was about, they might give simple one-word answers, such as “mortality” or “existence.”

More specifically, the essays in this book use their subjects to explore the death of Butler’s mother from cancer, and the author’s estranged relationship with her father.
