Cheap Astronomy - Dear CA Ep. 126: Going Deeper

Hosted by Steve Nerlich.


Dear Cheap Astronomy – What is the right message to send to the
aliens?


Keen listeners may be familiar with Cheap Astronomy’s ongoing
despair at Earth’s lacklustre


attempts at communication with the wider Universe. A few episodes
back we ran through a


history of deliberate communications to date, about 90 per cent
of which have been music – well


mostly digitized and some analog radio transmissions of music.


 


Dear Cheap Astronomy – Can we drill through the ice and find life
on Europa?


Firstly, there are quite a few moons out there with suspected
subsurface oceans – Ganymede


and Calisto around Jupiter, Enceladus and Dione around Saturn –
there’s even a suspicion that


Ceres, an asteroid rather than a moon, may have one.


Everyone gets excited about Europa, because it’s hot.
