365 Days of Astronomy 26 Aug 2009, 06:34 UTC Description: In August 1989, the Voyager 2 spacecraft performed the first reconnaissance with the solar system’s outermost major planet, Neptune. Now, 20 years later, the Voyager mission Project Scientist, Dr Ed Stone, joined me for an interview reliving some of those momentous events of that remarkable week of discovery in August 1989, and we hear about the impact Voyager had on future planetary missions. Voyager 2’s final encounter was a remarkable moment in history, marking the end of humanity’s first survey of the solar system. Mission control at the Jet Propulsion Laboratory in Pasadena, California, was packed by the world’s press and the world’s top planetary scientists. The exciting results from that mission, including Neptune’s large dark spot, fast moving white clouds, and a remarkably active surface of Neptune’s moon, Triton, are now well known. Voyager’s mission helped define future orbital missions to the outer planets.Bio: Martin Ratcliffe is Director of Professional Development for Sky-Skan, a leading digital planetarium manufacturer.

365 Days of Astronomy 25 Aug 2009, 00:00 UTC Today is the 92nd Birthday of the US National Park Service (NPS). The U.S. National Park Service was established in 1916 "to conserve the scenery, the natural and historic objects and the wild life therein, and to provide for the enjoyment of the same in such manner and by such means as will leave them unimpaired for the enjoyment of future generations..." Ranger Chad Moore will lead you on a search for dark skies through the 9-class Bortle Scale. This is the third in a series of IYA podcasts from the National Park Service. National Park Service's Night Sky Program www.nature.nps.gov/air/lightscapes Chad Moore is a National Park Service scientist and the manager of the Night Sky Program. He has a master’s degree in earth science, but has spent the last 10 years looking beyond our planet. His team developed a method for measuring light pollution and, thereby allowing precise tracking of sky quality. Chad was also instrumental in the development of the International Dark-sky Association’s Dark Sky Park program and is involved in several outreach efforts. ---------------------------------------------------------------------------------------------------------- SPONSOR: Anonymous The 365 Days of Astronomy Podcast is a project that is publishing one podcast per day, 5 to 10 minutes in ...
IRrelevant Astronomy 24 Aug 2009, 20:30 UTC Linda Hamilton attempts to foil the robots' plans of Universal conquest; meanwhile, Dean Stockwell explains the concept of ''looking back in time'' at objects in space, and how it helps astronomers understand how the Universe has evolved.
Are We Alone? 24 Aug 2009, 07:00 UTC Humans have not gone unnoticed on this planet. We’ve left our mark with technology, agriculture, architecture, and a growing carbon footprint. But where is this trajectory headed?
