    The Problem With "The Rare Earth Hypothesis"

    The Rare Earth Hypothesis suggests that our planet may the product of an incredibly improbable sequence of events, and thus perhaps intelligent life is extremely rare in the cosmos. Here we tackle this highly influential idea and the arguments behind it. But, digging deeper, we'll uncover some problems with the Rare Earth idea - some of which strike to the very core of our scientific quest.Written & presented by Prof David Kipping→ Support our research program: https://www.coolworldslab.com/support→ Get Stash here! https://teespring.com/stores/cool-worlds-storeTHANK-YOU to our supporters D.

    Eyeball Earths

    Earth-sized planets found in the habitable-zones of low-mass stars are likely to become tidally locked to the star, with one side baked in perpetual sunlight and other trapped in an eternal night. These so-called "Eyeball Earths" turn out to be extremely common and some famous examples include Proxima b and the planets around TRAPPIST-1. Here, we explain why this tidal locking happens and what it means for the potential habitability of these alien worlds.::More about this Video::► "Discovery of a Planet around our Nearest Star: Proxima b" Cool Worlds video by Dr Guillem Anglada: https://youtu.be/59ClESB1AqA► "Proxima b: Transits, Habitability & How to Get There!"

    Discovery of a Jupiter Twin!

    The Cool Worlds Lab just announced the discovery of the first transiting Jupiter-analog outside the Solar System, named "Kepler-167e". The transit method has been incredibly successful at finding exoplanets, with thousands now known thanks to NASA's Kepler Mission. But, planets on wide orbits, like Jupiter, are very tricky to find with this technique. Prof Kipping explains how his team overcame these obstacles to make this important discovery, opening the door to learning about alien Jupiters in much more detail.::More about this Video::► Kipping et al.
