In the eleventh episode, Exocast-11b:
- Hannah covers all the incredible news about the Trappist-1 system, talking us through the discovery of seven new earth-sized worlds around this nearby ultra-cool dwarf.
- Andrew talks about the philosophy of exoplanets, from the ancients, through the dark ages, and into the modern era.
- And Hugh sits in at the exocast newsdesk to cover the release of 60,000 HIRES RVs, new transit-hunting surveys MASCARA and BRing, the star HAT-P-2 beating to the rhythm of its planet, and more controversy over how to define a planet.
- And Andrew choose the elusive TRAPPIST-1 h, the coldest of the seven dwarfs, as our adopted planet of the week.

In Exocast-9b we take a special look at SETI and the Search for Extra Terrestrial Intelligence with expert guest Dr Duncan Forgan from the University of St Andrews.
- Hugh takes a VOXBOX of students at the University of Warwick looking at the Drake Equation which was the progenitor to SETI.
- Hannah dives into the science fiction realm to look at SETI’s influence in pop culture.
- Andrew has a look to the future of SETI and “intelligent” life on Earth and Exoplanets.
