Podcasts:
Opening the door to the paying public means that less healthy individuals will soon have access to space--if their doctors approve. John Matson reports
The Cassini orbiter spotted a river system on Titan that NASA likens to a miniature version of the Nile River, but flowing with liquid ethane and methane. John Matson reports
NASA has plans for another Mars rover, but no trips scheduled for exotic places like Titan or Europa. John Matson reports
A proof-of-concept 3-D printing job using lunarlike material shows that quick-and-dirty tools or spare parts could be manufactured on the moon. John Matson reports
Global 3-D climate simulations for plausible Martian atmospheres show that even with a much thicker CO2 layer, the greenhouse effect could not have warmed Mars above freezing. John Matson reports.
Thanks to gravitational lensing by a cluster of galaxies, the light emitted by a small galaxy 13.3 billion years ago has reached Earth. John Matson reports
A planet at least seven times as massive as Earth orbits comfortably in the habitable zone of the star HD 40307. John Matson reports
Fomalhaut b looked like an exoplanet to some astronomers and like dust to others. But new analyses strengthen the planet view. John Matson reports
A chemical analysis of lunar samples now points to the solar wind being behind the ultrathin dusting of water molecules first detected in 2009 from spacecraft measurements. John Matson reports
An analysis of the Huygens probe's sensor data has reconstructed bouncing and skidding, moments before it came to rest on Titan. John Matson reports
A star orbiting the galactic center's black hole in just 11.5 Earth years should provide data for studying how gravity works near an extremely massive object. John Matson reports
Smaller ground-based telescopes produce research results that get more citations per dollar spent than the big guys. John Matson reports
UV light, which radiates from stars and galaxies, can induce rapid changes in icy hydrocarbon molecules cooled to 5 kelvins, as on a comet. John Matson reports
In the J0651 binary system two white dwarf stars orbit each other in less than 13 minutes--and it's getting a little faster all the time. John Matson reports
On September 5th NASA's Dawn spacecraft left the asteroid Vesta and set sail for the dwarf planet Ceres, where it will arrive in 2015. John Matson reports
