Cool Worlds

Cool Worlds

Space, astronomy, exoplanets, astroengineering and the search for extraterrestrial life & intelligence.

The Cool Worlds Lab (http://coolworldslab.com), based at the Department of Astronomy, Columbia University, is a team of astronomers seeking to discover and understand alien worlds, particularly those where temperatures are cool enough for life, led by Professor David Kipping.

    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?

    The First Exoplanet Claim: Captain William S Jacob

    In 1855, Captain William Stephen Jacob authored a paper in the Monthly Notices of the Royal Astronomical Society claiming that a planet likely existed in the binary star system 70 Ophiuchi. Although his claim ended being wrong, it's pretty remarkable that someone was even thinking about doing this with scientific methods at the time! Here we get into Jacob's claim, what went wrong, and what legacy this has left us with. ::More about this Video:: ► Captain William S Jacob, "On Certain Anomalies Presented by the Binary Star 70 Ophiuchi": http://adsabs.harvard.edu/abs/1855MNRAS..15..228J ► Information compiled about Captain William Stephen Jacob and family by his living descendant, Kenneth Jacob: http://www.myjacobfamily.com/favershamjacobs/williamstephenjacob.htm ► Thomas See, "Researches on the orbit of 70 Ophiuchi, and on a periodic perturbation in the motion of the system arising from the action of an unseen body": http://adsabs.harvard.edu/abs/1896AJ.....16...17S ► Forest Ray Moulton, "The limits of temporary stability of satellite motion, with an application to the question of the existence of an unseen body in the binary system 70 Ophiuchi": http://adsabs.harvard.edu/abs/1899AJ.....20...33M ► Outro music by Taylor Davis: https://www.youtube.com/watch?v=dl9kI1yQKZk ::Playlists For Channel:: Latest Cool Worlds Videos ► http://bit.ly/NewCoolWorlds Cool Worlds Research ► http://bit.ly/CoolWorldsResearch Guest Videos ► http://bit.ly/CoolWorldsGuests Q&A Videos ► http://bit.ly/CoolWorldsQA Science of TV/Film ► http://bit.ly/ScienceMovies ::Follow us:: SUBSCRIBE to the channel http://bit.ly/CoolWorldsSubscribe Cool Worlds Lab http://coolworlds.astro.columbia.edu Twitter https://twitter.com/david_kipping Instagram https://www.instagram.com/cool.worlds THANKS FOR WATCHING!!

    Is Time an Illusion? | Prof Sean Carroll

    We caught up with Prof Sean Carroll at a recent astronomy conference and got his thoughts about time. Time may seem like a fundamental property of the Universe, but actually there's nothing in quantum theory which requires this to be so. Prof Carroll explains how time being merely an illusion, an emergent property rather than a fundamental one, is actually compatible with our best understanding of nature. This is one of two videos we shot with Sean so look out for the second video later in the year! ::More about this Video:: ► Sean Carroll: "From Eternity to Here" book available on Amazon: https://www.amazon.com/Eternity-Here-Quest-Ultimate-Theory/dp/0452296544 ► Sean Carroll's blog "Preposterous Universe" at https://www.preposterousuniverse.com/blog/ ► 229th Meeting of the American Astronomical Society: https://aas.org/meetings/aas229 ► Background music by Hans Zimmer, Interstellar OST ::Playlists For Channel:: Latest Cool Worlds Videos ► http://bit.ly/NewCoolWorlds Cool Worlds Research ► http://bit.ly/CoolWorldsResearch Guest Videos ► http://bit.ly/CoolWorldsGuests Q&A Videos ► http://bit.ly/CoolWorldsQA Science of TV/Film ► http://bit.ly/ScienceMovies ::Follow us:: SUBSCRIBE to the channel http://bit.ly/CoolWorldsSubscribe Cool Worlds Lab http://coolworlds.astro.columbia.edu Twitter https://twitter.com/david_kipping Instagram https://www.instagram.com/cool.worlds THANKS FOR WATCHING!!

    Why We Might Live in a "Barely Habitable" Universe

    Use code coolworlds at https://incogni.com/coolworlds to get an exclusive 60% off an annual Incogni plan. Intelligent design purports that the Universe was made by a creator - God. One of the arguments often invoked to make this case is that the physical constants of the Universe are (apparently) finely tuned to permit life. But cosmologist Denis Sciama presented a thought-provoking analysis of this line of thought and suggested it might be possible to even test intelligent design. Join us today as we explore this fascinating concept.

    Classifying Worlds

    Is there a way to naturally classify the different types of planets in the Universe? Two of the most fundamental properties of any object are its mass and size and generally one expects size to increase as we add more mass. The relationship between size and mass itself changes though at certain points, and this offers a clear way to classify worlds. Graduate student Jingjing Chen of the Cool Worlds Lab discusses one component of her new paper which does just this, classifying planets based off their mass and size and concluding that just four broad categories of planets explain the data. ::More about this Video:: ► Chen & Kipping (2016), "Probabilistic Forecasting of the Masses and Radii of Other Worlds": http://arxiv.org/abs/1603.08614 ► "Forecaster" open-source software package: https://github.com/chenjj2/forecaster ► Outro music by Taylor Davis: https://www.youtube.com/watch?v=dl9kI1yQKZk ::Playlists For Channel:: Latest Cool Worlds Videos ► http://bit.ly/NewCoolWorlds Cool Worlds Research ► http://bit.ly/CoolWorldsResearch Guest Videos ► http://bit.ly/CoolWorldsGuests Q&A Videos ► http://bit.ly/CoolWorldsQA Science of TV/Film ► http://bit.ly/ScienceMovies ::Follow us:: SUBSCRIBE to the channel http://bit.ly/CoolWorldsSubscribe Cool Worlds Lab http://coolworlds.astro.columbia.edu Twitter https://twitter.com/david_kipping Instagram https://www.instagram.com/cool.worlds THANKS 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.

    A Machine That Can Predict Exoplanets

    Exciting new research from the Cool Worlds Lab has delved into the use of machine learning and artificial neural networks for astronomy. In new work from David Kipping & Chris Lam here at Columbia, we've shown how a machine can predict the presence of extra planets in known planetary systems using just a few pieces of information about the system. Chris Lam gives a neural network 101 and explains our implementation works. ::More about this Video:: ► Kipping & Lam 2016, "Transit Clairvoyance: Enhancing TESS follow-up using artificial neural networks": https://arxiv.org/abs/1611.04904 ► Tamayo et al.

    A Cloaking Device for Planets

    NSF Graduate Fellow Alex Teachey of the Cool Worlds Lab explains our new paper which devises a method to cloak entire planets from extraterrestrial civilizations! This was a really fun little paper which started out from the idea of how to broadcast or signal our presence, but as we worked on it we realized it could also be used a cloaking device too.
