A JuMBO Mystery - This Shouldn't Happen!
Some startling discoveries from JWST and now Euclid and shaking up our ideas of planet formation and evolution - free floating worlds that really tax our current theories and could be just the tip of the iceberg. Join us today as we explore a "jumbo" mystery that's recently emerged in astronomy...

The Great American Eclipse 2017
Get ready! On August 21st 2017, Americans will be treated to a rare total Solar eclipse. From coast to coast, everyone in the US should be able to see at least a partial eclipse and be within a day's drive of catching the total eclipse. Here's a quick rundown of what to expect, where to go and how to plan your trip. ::More about this Video:: ► The web app you can use to plan your trip (as shown in the video) is available at www.GreatAmericanEclipse.com ► NASA's page on the upcoming eclipse: http://eclipse.gsfc.nasa.gov/SEgoogle/SEgoogle2001/SE2017Aug21Tgoogle.html ► Where to buy your glasses from: https://www.greatamericaneclipse.com/store/ and http://www.eclipse2017.org/glasses_order.htm ► 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!!

Are Dyson Spheres Physically Possible?
Use code coolworlds at https://incogni.com/coolworlds to get an exclusive 60% off an annual Incogni plan. The idea of Dyson Spheres was a radical proposal by the physicist Freeman Dyson, an enormous shell of material enveloping a star. Dyson's idea may be over half a century old, but interest in looking for such objects has only grown in the decades since. But how would such structures work? Are they physically even possible? And what might someone use them for? Today, we dive into the physics of Dyson spheres. Written & presented by Prof. David Kipping. Edited by Jorge Casas.

Alien signal received from HD 164595?
Dr Seth Shostak, Senior Astronomer of the SETI Institute, was at the New England Fall Astronomy Festival with me last week and I took the opportunity to ask him about the news reports of a SETI signal detected in Russia from the star HD 164595. Dr Shostak explains why he's not convinced that we've just heard from another civilization.

Do "Grabby Aliens" Solve The Fermi Paradox?
Thanks to Storyblocks for sponsoring this video! Download unlimited stock media at one set price with Storyblocks: https://www.storyblocks.com/CoolWorlds There are many possible solutions to the Fermi Paradox but a few have risen to particular prominence - including the "Grabby Aliens" hypothesis. Today, we'll explore what this solution proposes, what it assumes, and ultimately three reasons why I personally don't think it's right. Written & presented by Prof. David Kipping.

Climate Emergency? Global Sea Ice at Anomalously Low Levels
This week a plot showing the global sea ice over time went viral due to shockingly low levels, smashing previous records. The plot was so weird that we decided to check out the data for ourselves and see if it was legit. Indeed, we can reproduce this alarming plot and provide some links and scripts for any of you who want to go ahead and try yourselves. Here we get into why we think these kinds of weird observations may become more common in the future. ::More about this Video:: ► National Sea and Ice Data Center archive of sea ice extent data: https://nsidc.org/data/docs/noaa/g02135_seaice_index/ ► My Mathematica script used to generate a confirming plot: https://github.com/davidkipping/seaiceextent ► Two of the first tweets publicizing the viral plot, Zach Labe (https://twitter.com/ZLabe/status/798913080168095744) and Eric Holthaus (https://twitter.com/EricHolthaus/status/800067428419940352). ► Wipneus archive of plots: https://sites.google.com/site/arctischepinguin/home/sea-ice-extent-area/grf ► Eric Holthaus blog article about the viral plot: http://tinyletter.com/sciencebyericholthaus/letters/today-in-weather-climate-sea-ice-tipping-point-edition-monday-november-21th ► Guardian article on record Arctic temperatures: https://www.theguardian.com/environment/2016/nov/22/extraordinarily-hot-arctic-temperatures-alarm-scientists ► CNN article on record Arctic temperatures: http://www.cnn.com/2016/11/18/world/sea-ice-arctic-antarctic-lows/ ► Conrath at al.

How often does life start on other worlds?
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. ::More about this Video:: ► The paper by Scharf & Cronin (2016), "Quantifying the Origins of Life on a Planetary Scale": https://arxiv.org/abs/1511.02549 ► Drake Equation explained on the SETI website: http://www.seti.org/drakeequation ► 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!!

From Wobbles to Worlds - Discovery of The Exoplanet Edge!
Thanks to Incogni for sponsoring us. Use the code coolworlds at https://incogni.com/coolworlds to get an exclusive 60% off an annual Incogni plan. Today we explore what could be considered a classic problem in exoplanetary science, yet one which has eluded astronomers for decades. Transit timing variations (TTVs) are seen in thousands in systems, literally wobbling worlds. Yet for the vast majority of cases, we have no solution for the culprit. Today, we present new research from our team that finds analytic expressions for the allowed solution space and reveals the startling existence of an "exoplanet edge". Written & presented by Prof. David Kipping & Daniel Yahalomi. Edited by Jorge Casas & David Kipping.

Could A.I. Replace Scientists?
It's getting harder to harder to ignore the potential disruptive power of AI in research. Scientists are already using AI tools but could the future lead to complete replacement of humans? How will our scientific institutions transform? These are difficult questions but ones we have to talk about in today's episode.

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.
