Grateful Dead Percussionist Makes Music From Supernovas 57

At the "Cosmology At the Beach" conference earlier this month, Grammy-award winning percussionist Mickey Hart performed a composition inspired by the eruptions of supernovae. "Keith Jackson, a Berkeley Lab computer scientist who is also a musician, lent his talents to the project, starting with gathering data from astrophysicists like those at the Berkeley Lab’s Nearby Supernova Factory, which collects data from telescopes in space and on earth to quickly detect and analyze short-lived supernovas. 'If you think about it, it's all electromagnetic data — but with a very high frequency,' Jackson said of the raw data. "What we did is turn it into sound by slowing down the frequency and "stretching" it into an audio form. Both light and sound are all wave forms — just at different frequencies. Our goal was to turn the electromagnetic data into audio data while still preserving the science.'"

NASA To Cryogenically Freeze Satellite Mirrors 47

coondoggie writes "NASA said it will soon move some of the larger (46 lb) mirror segments of its future James Webb Space Telescope into a cryogenic test facility that will freeze the mirrors to -414 degrees Fahrenheit (~25 K). Specifically, NASA will freeze six of the 18 Webb telescope mirror segments at the X-ray and Cryogenic Facility, or XRCF, at NASA's Marshall Space Flight Center in Huntsville, Alabama, in a test to ensure the critical mirrors can withstand the extreme space environments. All 18 segments will eventually be tested at the site. The test chamber takes approximately five days to cool a mirror segment to cryogenic temperatures."

Apple Orders 10 Million Tablets? 221

Arvisp writes "According to a blog post by former Google China president Kai-Fu Lee, Apple plans to produce nearly 10 million tablets in the still-unannounced product's first year. If Lee's blog post is to be believed, Apple plans to sell nearly twice as many tablets as it did iPhones in the product's first year."
