We’ve reached Neptune, the final planet in our tour through the solar system – but don’t worry! The tour’s not over, but after this week we’ll be all out of planets. Neptune has a controversial story about its discovery, some of the strongest winds in the solar system and some weird moons.

This week, we’re on to the next planet in the solar system. Having only visited it up close once with Voyager 1, we don’t know much about this sideways-spinning ice giant. But today we’ll cover what we do know, including its faint rings, sideways axis of rotation and rocky core – a first in the gas planets we’ve encountered so far in our tour.

Podcast: Inflation

We interrupt this tour through the Solar System to bring you a special show to deal with one of our most complicated subjects: the Big Bang. Specifically, how it’s possible that the universe could have expanded faster than the speed of light. The theory is called the inflationary theory, and the evidence is mounting to support it. Einstein said that nothing can move faster than the speed of light, and yet astronomers think the universe expanded from a microscopic spec to become larger than the solar system, in a fraction of a second.

Last week we talked about rubble, this week we’re going to dig into the largest planet in the Solar System: Jupiter, but will it all just be hot gas? There’s so much to talk about, we’ve decided to break this up into two shows. This week we’re going to just talk about Jupiter, and then next week, we’re going to cover its moons.
