If you haven't already found this then check out this weeks Planetary Radio. The topic this week is not surprisingly the debate of planetary definition. The special guest is author Dava Sobel, author of the excellent books 'Planets'.
At the end of the programme you'll here the poem "Solar System 2.0" by our friend Stuart Atkinson. It's great to hear Stuart getting some real recognition for his excellent poems, and Dava Sobel is complementary as well.
You can check out the radio show here and more of Stu's poems on The 'Verse.
