    Could We Detect the Death Star?

    To celebrate the release of Star Wars Rogue One this weekend, let's ask the question - could we detect the Death Star with our current telescopes? Remarkably astronomers have been thinking about the detectability of alien megastructures, such as the Death Star, for many years and we can apply some scientific thinking to get to the answer.::More about this Video::► Companion video on Martin Archer's channel, "Is the Death Star a Star?": https://youtu.be/Q4CKSekJzxk► Kipping & Teachey 2016, "A Cloaking Device for Transiting Planets": https://arxiv.org/abs/1603.08928► Cool Worlds video by Alex Teachey about our laser cloaking system: https://www.youtube.com/watch?v=z1Pqqf_6J9w► Most recent results from exomoon hunting, Kipping et al. 2015, "The Hunt for Exomoons with Kepler (HEK): V.

    An Event So Deadly it Makes Parts of the Galaxy Inhospitable

    Space is a bleak, hostile environment. Asteroid strikes, supernovae and gamma ray bursts could wipe us out at any moment. But could certain parts of the galaxy be more dangerous than others?

    What is an Alien Megastructure?

    Alien megastructures are back in the headlines after some new research published last week. It has been claimed that Tabby's Star is confirmed to be steadily dimming, which is completely unexpected behavior for a star. Prof Kipping explains what we know (and don't know) about this mysterious star and what astronomers really mean by "alien megastructures".::More about this Video::► Montet & Simon (2016), "KIC 8462852 Faded Throughout the Kepler Mission": http://arxiv.org/abs/1608.01316► Schaefer (2016), "KIC 8462852 Faded at an Average Rate of 0.165+-0.013 Magnitudes Per Century From 1890 To 1989": http://arxiv.org/abs/1601.03256► Boyajian et al.

    Why Finding Earth-Sized Planets is Hard

    The transit method of finding exoplanets is easier for big planets than small planets. But new work from the Cool Worlds Lab shows that transits disfavor the detection of small, Earth-sized planets even more than previously realized. Emily Sandford, a third-year graduate student with the Cool Worlds Lab at Columbia, explains our new paper which derives these biases, allowing astronomers to correct for these effects when figuring out how many Earths there really are.::More about this Video::► Kipping & Sandford (2016), "Observational biases for transiting planets": http://arxiv.org/abs/1603.05662► Outro music by Taylor Davis: https://www.youtube.com/watch?v=dl9kI1yQKZk::Playlists For Channel::Latest Cool Worlds Videos ► http://bit.ly/NewCoolWorldsCool Worlds Research ► http://bit.ly/CoolWorldsResearchGuest Videos ► http://bit.ly/CoolWorldsGuestsQ&A Videos ► http://bit.ly/CoolWorldsQAScience of TV/Film ► http://bit.ly/ScienceMovies::Follow us::SUBSCRIBE to the channel http://bit.ly/CoolWorldsSubscribeCool Worlds Lab http://coolworlds.astro.columbia.eduTwitter https://twitter.com/david_kippingInstagram https://www.instagram.com/cool.worldsTHANKS FOR WATCHING!!

    How Many Planets in the Universe? | Part 1: Our Galaxy

    Have you ever wondered just how many planets there are in the Universe? So have we! We haven't surveyed the entire Universe (!) but based of the occurrence rate of planets in our local part of the cosmos, we can try to carefully extrapolate the total. In Part 1 of this mini-series, we focus on our galaxy, the Milky Way and explain why even here there is a great deal of uncertainty.::More about this Video::► Cassan et al.

    How Game Theory Can Help Us Find Aliens

    Could it be that aliens are trying to communicate with us right now, but we're just not listening in the right way? They might have chosen a specific frequency, time or method of communication that we just never thought to try. In game theory, two players can co-operate towards a common goal even without communication. The idea is called a Schelling point - today we'll explore what this is and how it affects our search for life in the Universe.Written & presented by Prof David Kipping.
