There was likely a time where the waters of earth where purple. In this episode we explore why. And what that means for our search for life outside earth.

Ever since mankind learned that there are other worlds besides earth out there in the cosmos we have been wondering:

What is going on on those worlds?

Is there anything alive out there?

Maybe even intelligent civilizations?

In this episode we don't answer those questions, because nobody knows the answer - yet. What we will do is to discuss a few ways of how these questions could be answered. And you will get to hear my own personal predictions of when I will have an answer for you.

In this episode we go for the big picture. Where does the gold in your wedding ring and the platinum in the catalytic converter in your car your come from? And why do we have so much of it?

In this episode we are exploring some of the astronomical background of Matariki the new year festival of the Maori from New Zealand.

This episode is all about constellations. What are constellations? Where do they come from? What can they tell you? And how can you use them to your own benefit?

To help you spot constellations in our night skies you can use a free software called Stellarium.
