Many of you wanted me to talk about the different interstellar propulsion ideas out there so we figured a fun way to compare them all would be in a tier list! Today we take a look at 14 different methods proposed to explore the stars. Let us know your rankings down below in the comments.

Written & presented by Prof. David Kipping. Edited by Jorge Casas.

Astrobiology an exciting new field studying how life begins and the conditions needed both on Earth and elsewhere in the cosmos. Columbia's Director of Astrobiology, Dr Caleb Scharf, dropped into the Cool Worlds Lab to tell us about his new paper which created a "Drake Equation" for abiogenesis. Whilst we can only guess at many of the factors in the equation right now, it provides a framework for tackling this problem going forward.

What kind of evidence would be needed to convince the world of alien life? Sagan said that "extraordinary claims require extraordinary evidence", but what exactly is "extraordinary"? Today we explore the difficult problem of dealing with potentially ambiguous evidence and how it might affect our search for life.

Many exoplanets, including hot-Jupiters, have been observed to orbit the star the wrong way round, in retrograde orbits relative to the star's rotation. Prof. Smadar Naoz from UCLA visited the Cool Worlds Lab and explained why this is so odd and how we might explain these bizarre observation.
