In March 2015 there will be an eclipse of the Sun. From the UK (apart from a couple of very tiny northern parts) it will be visible as a partial eclipse. In this month’s episode Edward Gomez and I chatted about eclipses and their historical significance.

February 2015 also saw the release of new data from the Planck Satellite. I spoke to Hiranya Peiris, from University College London, about what the results are telling us.

Originally broadcast (in edited form) on 26th February 2015 as part of Pythagoras’ Trousers on Radio Cardiff.

For those only after the discussion of the Planck results, you can listen to the version below.
