We listen, but we don't send. Why do we expect aliens to transmit if we don't? Many have voiced concerns about any programs designed to broadcast our presence - afterall, they may not be friendly. Although it may be a popular idea in science fiction, what do scientists say about this scenario? Today we explore the arguments for and against messaging, and what it might imply about the type of civilization that chooses to engage in messaging...Written and presented by Prof David Kipping.

Could we avert climate change by pulling carbon dioxide out of the atmosphere? Could we not just stop, but actually *reverse* the damage done? Unfortunately, most don't fully appreciate just quite how much CO2 we've emitted and the outrageous scale of the problem facing us. Today, we apply the fundamental principles of thermodynamics to question whether this is even feasible.Written & presented by Prof. David Kipping. Edited by Jorge Casas.

In 1994, Miguel Alcubierre gave all of us hope as he found a solution within general relativity that would cause the necessary warping of space. But after nearly 30 years of further study, what does our current understanding of physics say about the feasibility of a warp drive?Written & presented by Prof. David Kipping.

The Cool Worlds Lab is trying to find the first exomoon, a moon around a planet outside the Solar System. But, exomoons have been eluding us for a few years now. So why are they so hard to find and what do we know so far? Get up to date with the latest limits and prospects for detection. You can find the latest paper on constraints on exomoons at ::More about this Video::► Hunt for Exomoons with Kepler (HEK) Project website: www.exomoon.org► HEK Project Twitter feed https://twitter.com/hek_project► Kipping et al.
