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

Classifying Worlds

Cool Worlds ·

2026/09/10

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

A Machine That Can Predict Exoplanets

Cool Worlds ·

2026/09/10

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

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.

Bayesian Worlds

One branch of statistics, called Bayesian statistics, is becoming increasingly important in detecting new planets. Emily Sandford, a second-year graduate student with the Cool Worlds Lab at Columbia, explains our new paper and the concept of Bayesian priors, hopefully providing astronomers the tools we need to analyze new discoveries!::More about this Video::► Kipping & Sandford (2016), "Observational biases for transiting planets": http://arxiv.org/abs/1603.05662► Outro music by Taylor Davis:

How to Characterize Proxima b's Atmosphere

2026/09/09

As regular watchers of the channel may remember, this summer astronomers announced the discovery of a potentially Earth-like planet orbiting our nearest star, Proxima Centauri. Sadly, research at the Cool Worlds Lab was unable to find any evidence that Proxima b transits its star, which is a blow for those hoping for near-term characterization of its atmosphere. But! Dr Jayne Birkby comes to the rescue and explains here how an alternative technique should work if we can wait a few years! Thanks to

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.
