◊ Waking the Intonarumori

If we have a SETI program, then they probably do, too.

Each episode of Waking the Intonarumori is dedicated to the aliens of one of our neighboring exoplanets, who (if they're listening) will have to wait some time to hear us. How long? Here's a list of known habitable exoplanets* and how long until they receive our signal:

Transmissions on this date will reach the aliens:
