Description

The Discussion: Beginning the show droning on about us for bit, we cover Jen presenting her latest paper at the dust conference (yes, there is such a thing) in Marseilles, and filming in the wilds of Wales at night for the BBC's Weatherman Walking TV programme.

The News: Rounding up the astronomy news this month we have:

Main News story: Did humanity narrowly escape extinction in 1908?

The Sky Guide: This month we're taking a look at the constellation of Cassiopeia with a guide to its history, how to find it, a couple of deep sky objects and a round-up of the solar system views on offer in November.

Guide to the Electromagnetic Spectrum: In November we conclude our look at the electromagnetic spectrum, what, it is, what is shows us and why it's so important to astronomers. This month we explain the gamma-ray part of the spectrum and its relevance to astronomy.

Q&A: How do you tell the difference between a star that is nearer to the end of its lifecycle, and a younger star that is actually travelling away from us at a faster speed? From Tony Horton in Herefordshire, England.
