Monday, December 2, 2013- No evidence for extraterrestrial civilizations in infrared astronomy survey

4Dec

A serious scientific constraint on extraterrestrial civilizations.  Regular cohost DJ Gigayear (aka gully) reports on current research showing no evidence for extraterrestrial civilizations.  Over 1 million galaxies were surveyed with the Widefield Infrared Survey Explorer (WISE), an infrared space telescope.  None of these galaxies show infrared radiation levels consistent with more than 15% of their stars being surrounded by solar panels- so called "Dyson Spheres".  The cohosts discuss the meaning of this result, and why we might expect to see Dyson spheres in the first place.  The story was inspired by ongoing research supported by the Templeton Foundation, and performed by Professor Jason Wright and collaborators at Penn State University's Center for Exoplanets and Habitable Worlds.

Director of the Texas Memorial Museum, Ed Theriot describes some of the treasures of the Texas Memorial Museum on the University of Texas at Austin Campus.  The museum has lost 90% of its funding, which will cut virtually all museum activities.  Though the Italian marble walls of the building will stay open for museum guests, it will no longer update exhibits or host special events.  Ed Theriot describes the giant Texas Pterosaur, the largest flying animal ever found- one of Time Life's top 100 scientific discoveries in the 20th century.  We learn about diatoms, which are tiny 20-50 micrometer sized living creatures, helpful for studying water quality and other changes in environmental phenomena like oil exploration.  Diatoms make about half the oxygen we breathe!
