|Life imitates art ... sorta|
|The darker, the better|
Years ago, a large expanse encompassing parts of Virginia, West Virginia, and Maryland was set aside as the National Radio Quiet Zone. Now "Chilean astronomical site becomes world’s first international dark sky sanctuary."
An emerging form of astronomy uses neutrinos. Those are electrically neutral, elementary subatomic particles that interact so weakly with other matter that if you shoot a stream of them at a light-year-thick wall of lead, half of them will pass through! Neutrinos, of course, were recently in the news, as "Neutrino scientists win Nobel Prize for Physics."
Fusion in the heart of the Sun is understood to produce an outpouring of neutrinos -- only when physicists looked for them, they found only 1/3 the quantity they expected. Solving that puzzle involved the discovery that neutrinos spontaneously change among their three types, and that property, in turn, required that neutrinos -- contrary to theory -- have nonzero (though very small) mass. Neat stuff!
What could be more star-oriented than the Museum of Science Fiction? Not much! So: I'll wrap up for today with a link to the 3Q15 report on progress getting the museum established. It can't hurt to have a new NASA grant.
