If there was life on other planets, what might it look like, and would they even bother coming to Earth? 

Lisa Kaltenegger is the Director of the Carl Sagan Institute to Search for Life in the Cosmos at Cornell and Associate Professor in Astronomy.  

She is a pioneer and world-leading expert in modelling potential habitable worlds and their detectable spectral fingerprint. Her research focuses on rocky planets circling other stars, looking at potentially Earth-like exoplanets in the Habitable Zone.

These micro-organisms may form life on other planets if there are suitable conditions. The panspermia theory suggests the idea that life on Earth originated in this manner.

9:00 Mediawatch 

Mediawatch looks at how Winston Peters' grievances against the media made headlines this week  - as soon as the new government took power. 

Also: reports that have put Wellington's mayor under pressure - and why are all the weekly TV politics shows going off the air now, just as the new government gets going.

10:10 Sebastian Faulks: On being Homo sapiens  

Sebastian Faulks, worldwide bestselling author of Birdsong, is back with a new thriller, inspired, he tells us by a tweet from Richard Dawkins. 

The Seventh Son tells the story of a young American academic Talissa Adam who offers to carry another woman's child, with no idea of the life-changing consequences. 

Sweeping between New York, London, and the Scottish Highlands, it is a novel about unrequited love, unearned power and what it means to be human.
