So it stands to reason that of the billions of Earth-like planets in our galaxy alone, there might be another that hosts life.
It’s a thought that is gaining more credence all the time, and now Nasa has released a fascinating book detailing how, or if, we might communicate with some of these worlds.
A new book made for Nasa called Archaeology, Anthropology and Interstellar Communication details the methods through which we might communicate with aliens. Although this artist's illustration is a bit fanciful, the authors suggest that Earth may already have been visited.
Some of the most interesting chapters tackle the issue of alien communication in the past, present and future.
In one section, for example, William Edmondson from the University of Birmingham considers the possibility that rock art on Earth is of extraterrestrial origin.

Vakoch explains how the methods via which aliens communicate might be vastly different from our own, making contact difficult. He says that messaging through sound, as we are used to on Earth, might not be possible.
‘On the other hand, vision and the use of images would appear to be at least plausible,’ he writes.
Jesus Diaz wrote for Gizmodo said that ”it’s comforting that NASA is thinking about human-alien communication under a new focus, one that is not purely based on the physical sciences of planetary research or exobiology, but that ties it with our current experience in trying to decipher our own archaeological and anthropological past.”
The book is titled Archaeology, Anthropology and Interstellar Communication.
It was edited for Nasa by Douglas Vakoch, Director of Interstellar Message Composition at the Seti Institute. Read full article here
It seems NASA has removed the page.
This is dummy text. It is not meant to be read. Accordingly, it is difficult to figure out when to end it. But then, this is dummy text. It is not meant to be read. Period.
