From NPR News, this is ALL THINGS CONSIDERED. I'm Melissa Block. And we begin this hour with Isaac. After pounding the Gulf Coast with high winds, nonstop rain and a powerful storm surge, Isaac is now churning through northern Louisiana. There, heavy rainfall brings a new threat, inland river flooding. Some of that flooding has strained a dam in Mississippi; 60,000 people downriver have been ordered to evacuate.
JazzSet returns to the 2011 Newport Jazz Festival for performances from two complementary bandleaders on the main Fort Adams stage: violinist Regina Carter and trumpeter Wynton Marsalis.
Regina Carter started playing violin as a 4-year-old Suzuki method student in Detroit, and later played in school and community orchestras. After attending the New England Conservatory of Music, she chose jazz as her primary direction. JazzSet first presented her from the 1995 Telluride Jazz Festival — on a stage in the mountains, playing into the open air.
With its all-sky infrared survey, NASA's Wide-field Infrared Survey Explorer, or WISE, has identified millions of quasar candidates. This image zooms in on one small region of the WISE sky, covering an area about three times larger than the moon. The WISE quasar candidates are highlighted with yellow circles.
"In one study, astronomers used WISE to identify about 2.5 million actively feeding supermassive black holes across the full sky, stretching back to distances more than 10 billion light-years away. About two-thirds of these objects never had been detected before because dust blocks their visible light. WISE easily sees these monsters because their powerful, accreting black holes warm the dust, causing it to glow in infrared light."
