Episode19:Astronomy Online

By Leave a Comment

There are many ways to participate in and learn about astronomy online.

In today’s episode, three examples of how the web is being used to share resources and build communities around Science http://www.sciencefile.org Space http://www.space.co.uk and Astronomy http://www.fedastro.org.uk .

Many astronomical societies are preparing or have already completed a program of speakers for the 2008/9 season. If you are a member I would encourage you exploit one or better still all three resources featured in today’s episode to advertise you societies events. You will be surprised at the visitors who may turn up.

Episode16:Astronomy – A cultural perspective

By Leave a Comment

You can’t think of Darwin without Wallace, Laurel without Hardy. In UK astronomy there is no more an enduring and familiar partnership than Henbest and Couper. Nigel and Heather have been writing, broadcasting, supporting and publicising astronomy for decades.

Their most recent project is a series of daily radio programs for BBC Radio4 called Cosmic Quest and an associated book History of Astronomy which together chart the story of how human societies through history and around the globe have attempted to understand the universe and their place within it.

Episode14:Titan

By 2 Comments

After a 7 year journey, Cassini/ Huygens arrived at Saturn in 2004 and Huygens landed on the surface of Titan on January 14th 2005. The only moon within the solar system known to have a substantial atmosphere.

On Monday 3rd of July 1989 it was possible to study the atmosphere of Titan from here on Earth when it occulted a 5.8mag star 28 Sagittarius. Ken Irving from Salford Astronomical Society describes the observation he made and video recording of the unexpected central flash. Available below.

Using data from the onboard Acoustic Sensor Unit, the Planetary Society compressed Huygens two and half hour descent into a 10 second audio clip.

After landing, Huygens continued to transmit data including those incredible pictures of the surface for another 70 minutes until the communication link to Earth – Cassini disappeared over the horizon. It would not come in range again for 40 days by when Huygens’ batteries were dead. There in its dark cold -180C deep freeze it remains. Probably intact. Professor John Zarnecki from the Open University who lead the Surface Science Package team talk a little about the achievements f the Cassini/Huygens mission.
